35 Case Interviews Examples from MBB / Big Four Firms

Studying case interview examples is one of the first steps in preparing for the  management consulting  recruitment process. If you don’t want to spend hours searching the web, this article presents a comprehensive and convenient list for you – with 35 example cases, 16 case books, along with a case video accompanied by detailed feedback on tips and techniques.

A clear understanding of “what is a case interview” is essential for effective use of these examples. I suggest reading our  Case Interview 101  guide, if you haven’t done so.

McKinsey case interview examples

What should I know about McKinsey Case interviews?

At McKinsey, case interviews often follow the interviewer-led format , where the interviewer asks you multiple questions for you to answer with short pitches.

How do you nail these cases? Since the questions can be grouped into predictable types, an efficient approach is to master each question type. However, do that after you’ve mastered the case interview fundamentals!

For a detailed guide on interviewer-led cases, check out our article on McKinsey Case Interview .

BCG & Bain case interview examples

Bcg practice cases.

• BCG – Written Case – Chateau Boomerang

Bain practice cases

• Bain – Coffee Shop Co.
• Bain – Fashion Co.
• Bain – Mock Interview – Associate Consultant
• Bain – Mock Interview – Consultant

What should I know about BCG & Bain case interviews?

Unlike McKinsey, BCG and Bain case interviews typically follow the candidate-led format – which is the opposite of interviewer-led, with the candidate driving the case progress by actively breaking down problems in their own way.

The key to acing candidate-led cases is to master the case interview fundamental concepts as well as the frameworks.

Some BCG and Bain offices also utilize written case interviews – you have to go through a pile of data slides, select the most relevant ones to answer a set of interviewer questions, then deliver those answers in a presentation.

What should I know about Deloitte case interviews?

Case interviews at Deloitte also lean towards the candidate-led format like BCG and Bain.

The Deloitte consultant recruitment process also features group case interviews , which not only test analytical skills but also place a great deal on interpersonal handling.

Accenture case interview examples

Accenture divides its cases into three types with very cool-sounding names.

Sorted in descending order of popularity, they are:

These are similar to candidate-led cases at Bain and BCG. albeit shorter – the key is to develop a suitable framework and ask the right questions to extract data from the interviewer.

These are similar to the market-sizing and guesstimate questions asked in interviewer-led cases – demonstrate your calculations in structured, clear-cut, logical steps and you’ll nail the case.

These cases have you sort through a deluge of data to draw solutions; however, this type of case is rare.

Capital One case interview examples

Capital One is the odd one on this list – it is a bank-holding company. Nonetheless, this being one of the biggest banks in America, it’s interesting to see how its cases differ from the consulting ones.

Having gone through Capital One’s guide to its cases, I can’t help but notice the less-MECE structure of the sample answers. Additionally, there seems to be a greater focus on the numbers.

Nonetheless, having a solid knowledge of the basics of case interviews will not hurt you – if anything, your presentation will be much more in-depth, comprehensive, and understandable!

Case interview example – Case video

The limitation of most official case interview examples is that they are either too short and vague, or in text format, or both.

To solve that problem for you, we’ve extracted a 30-minute-long, feedback-rich case sample from our Case Interview End-to-End Secrets Program .

This is a candidate-led, profitability case on an internet music broadcasting company called Pandora.

In 30 minutes, this candidate demonstrates the exact kind of shortcoming that most candidates suffer during real case interviews – they come in with sharp business senses, then hurt their own chances with inadequate techniques.

Here are seven notable areas where the candidate (and you) can improve:

Thanking Throughout the case, as especially in the opening, he should have shown more appreciation for the time the interviewer spent with him.

Structured opening The candidate’s opening of the case feels unstructured. He could have improved it by not mixing the playback and clarification parts. You can learn to nail the case in a 3-minute start through this video on How to Open Any Case Perfectly .

Explicitness A lot of the candidate’s thought process remains in his head; in a case interview, it’s better to be as explicit as possible – draw your issue tree out and point to it as you speak; state your hypothesis when you move into a branch; when you receive data, acknowledge it out loud.

Avoiding silence The silence in his case performance is too long, including his timeout and various gaps in his speech; either ask for timeout (and keep it as short as possible) or think out loud to fill those gaps.

Proactivity The candidate relies too much on the interviewer (e.g: asking for data when it can easily be calculated); you don’t want to appear lazy before your interviewer, so avoid this.

Avoiding repeating mistakes Making one mistake twice is a big no-no in consulting interviews; one key part of the consulting skill set is the ability to learn, and repeating your mistakes (especially if the interviewer has pointed it out) makes you look like someone who doesn’t learn.

Note-taking Given the mistakes this candidate makes, he’s probably not taking his notes well. I can show you how to get it right if you watch this video on Case Interview Note-Taking .

Nonetheless, there are three good points you can learn from the candidate:

The candidate sums up what he’s covered and announces his upcoming approach at the start and at key points in the case – this is a very good habit that gives you a sense of direction and shows that you’re an organized person.

The candidate performs a “reality check” on whether his actions match the issue tree; in a case interview it’s easy to lose track of what you’re doing, so remember to do this every once in a while.

The candidate prompts the interviewer to give out more data than he asked for; if anything, this actually matches a habit of real consultants, and if you’re lucky, your interviewer may actually give out important pieces you haven’t thought of.

These are only part of the “ninja tips” taught In our Case Interview E2E Secrets Program – besides the math and business intuition for long-term development, a key feature is the instant-result tips and techniques for case interviews.

Once you’ve mastered them, you can nail any case they throw at you!

For more “quality” practice, let’s have a mock case interview with former consultants from McKinsey, BCG, Bain, Oliver Wyman, Strategy& and many other consulting firms. They will help you identify your problem areas and give you actionable feedback, making your preparation much easier and faster.

Hi! This is Kim and welcome to another performance in the Tips & Techniques part of our amazing End-to-end program. You are about to hear a really interesting performance.

There is a common Myth that Profitability cases are easier. Well, for beginners, that’s may make sense, but I would argue that Profitability cases can be really tricky and candidates without good foundation will make about the same level of mistakes regardless of type of cases given.

The profitability case we are about to watch will show that. It’s a very unconventional

Profitability. It started out like a typical one but getting more and more tricky toward the end.

The candidate is fairly good in term of business intuition, but the Tips & Techniques aspect needs a lot of fine tune! Now let’s go ahead and get started! 

It’s actually a little better to playback the case information and ask clarifications. The candidate does not distinguish between the two and do both at a same time. Also, the candidate was asking these clarifications in an unorganized and unstructured fashion. This is not something terrible, but could have been better, especially when this is the very first part of the case, where the crucial first impression is being formed.

My pitch would sound like this:

“That’s a very interesting problem and I am happy to get the chance to solve it. First of all let me tell you my understanding of the case context and key objectives. Then I would like to ask a few clarifying questions regarding a few terminology and concepts. Both of these are to make sure that I will be solving the right problem.

So here is my understanding of the case: The client is ABC. Here are some DEF facts about the situation we just talked about. And the key case question is XYZ.

Does that correctly and adequately summarize the case?”

Once the interviewer confirms, I would move to the clarification part as follows: “Now I would like to ask a few clarification questions. There are three of them: No 1, … No 2, … and No 3, …”

You may see above pitch as obvious but that’s a perfect example of how you should open any cases. Every details matters. We will point out those details in just a second. But before we do that, it’s actually very helpful if you can go back, listen carefully to the above pitch, and try to point out the great components yourselves. Only after that, go back to this point and learn it all together.

Alright, let’s break down the perfect opening.

First of all, you hear me say: “That’s a very interesting problem and I am happy to get a chance to solve it”. This seems trivial but very beneficial in multiple ways:

1. I bought myself a couple of seconds to calm down and get focused. 2. By nature, we as human unconsciously like those who give us compliments. Nothing better than opening the case with a modest compliment to the interviewer.

And (c) I showed my great attitude towards the case, which the interviewer would assume is the same for real future consulting business problems.

You should do that in your interviews too. Say it and accompany it with the best smile you can give. It shows that you are not afraid of any problems. In fact, you love them and you are always ready for them.

Secondly, I did what I refer to as the “map habit”, which is to always say what you are about to do and then do it. Just like somebody in the car showing the drivers the route before cruising on the road. The driver would love it. This is where I said: “Let me tell you my understanding of the case context and key objectives. Then ABC…”.

Third, right at the beginning of the case, I try to be crystal clear and easy to follow. I don’t let the interviewer confused between playing the case vs. asking clarification questions. I distinguish between the two really carefully. This habit probably doesn’t change the outcome of how the case goes that much, but it certainly significantly changes the impression the interviewer has of me.

Fourth, in playing back the case, each person would have a different way to re-phrase. But there are three buckets to always include:

1. Who is the client 2. The facts regarding the client and the situation and (c) The key question and the objective of the case.

Fifth, after playing the case context and objectives, I pause for a second and ALIGN with the interviewer: “Does it correctly and adequately summarize the case?”. This is a habit that every consulting manager loves for young consultants to do. Nobody wants first-year folks to spend weeks of passion and hard-work building an excel model that the team can’t use. This habit is extensively taught at McKinsey, Bain and BCG, so therefore interviewers would love somebody that exhibits this habit often in case interview.

Lastly, when asking clarification questions, you hear me number them very carefully to create the strong impression that I am very organized and structured. I said I have three clarifying questions. Then I number them as I go through each. No.1, No.2, and No.3.

Sometimes, during interviews it’s hard to know exactly how many items you are going to get. One way is to take timeout often to carefully plan your pitch. If this is not possible in certain situations, you may skip telling how many items you have; but you should definitely still number your question: No.1, No.2; and so on. 

Just a moment ago, the candidate actually exhibited a good habit. After going through his clarification questions, the candidate ended by asking the “is there anything else” question. In this case, I actually give out an important piece of data.

Though this is not very common as not every interviewer is that generous in giving out data. But this is a habit management consultants have to have every day when talking to experts, clients, or key stakeholders. The key is to get the most data and insights out of every interview and this is the type of open-ended question every consultant asks several times a day.

To show of this habit in a case interview is very good!

There are three things I would like you to pay attention to:

First, it took the candidate up to 72 seconds to “gather his thoughts”. This is a little too long in a case interview. I intentionally leave the 72 seconds of silence in the recording so you get an idea of how long that is in real situations. But it’s worth-noting here is not only that. While in some very complicated and weird cases, it’s ok to take that long to really think and gather ideas. In this case, the approach as proposed by the candidate is very simple. For this very approach, I think no more than 15 to 20 seconds should be used.

No.2, with that said, I have told I really like the fact that this candidate exhibits the “map” habit. Before going straight to the approach he draws the overall approach first.

No.3. You also see here that the candidate tried to align the approach with me by asking my thoughts on it. As I just said on the previous comment, this is a great habit to have. Not only does it help reduce chance of going into the wrong direction in case interviews, but it also creates a good impression. Consulting interviewers love people doing it often!

Here we see a not-really-bad response that for sure could be much better. The candidate was going into the first branch of the analysis which is Revenue. I would fix this in 3 aspects:

First, even though we just talked about the overall approach, it’s still better to briefly set up the issue tree first then clearly note that you are going into one branch.

Second, this is not a must, but I always try to make my hypothesis as explicitly clear as possible. Here the candidate just implicitly made a hypothesis that the problem is on the revenue side. The best way to show our hypothesis-driven mindset is to explicitly say it.

Third, you hear this a ton of times in our End-to-End program but I am going to repeat it again and again. It is better to show the habit of aligning here too. Don’t just go into revenue, before doing that, give the interviewer a chance to agree or to actually guide you to Cost.

So, summarizing the above insights, my pitch would sound something like this:

“So as we just discussed, a profit problem is either caused by revenue or by cost. Unless you would like to go into cost first, let’s hypothesize that the problem is on revenue side. I would like to look deeper into Revenue. Do we have any data on the revenue?”

And while saying this, you should literally draw an issue tree and point to each as you speak.

There is an interesting case interview tip I want to point out here. Notice how the candidate responds after receiving two data points from me. He went straight into the next question without at least acknowledging the data received and also without briefly analyzing it.

I am glad that the candidate makes this mistakes… well, not glad for him but for the greater audience of this program. I would like to introduce to you the perfect habit of what you should react and do every time you have any piece of data during case interviews. So three things you need to do:

Step 1: Say … that’s an interesting piece of data. This helps the interviewer acknowledge that you have received and understand the data. This also buys you a little time. And furthermore, it’s always a good thing to give out modest compliments to the interviewer.

Step 2: Describe the data, how it looks, is there any special noteworthy trend? In this case, we should point out that revenue actually grew by more than 50%.

Also notice here that I immediately quantified the difference in specific quantitative measurement (in this case, percentage). Saying revenue went up is good, but it’s great to be able to say revenue went up by more than 50%.

Step 3: Link the trend identified back to the original case question and the hypothesis you have. Does it prove, disprove, or open up new investigation to really test the hypothesis? In this case, this data piece actually opened up new investigating areas to test the hypothesis that the bottleneck is within revenue.

My sample pitch for this step 3 would sound like this: “It’s interesting that revenue went up quite a bit. However, to be able to fully reject our hypothesis on the revenue, I would like to compare our revenue to that of the competitors as well.”

Then only at this point, after going through 3 steps above, I ask for the competitors’ revenue like the candidate did.

Notice here that I ended up asking the same question the candidate did. This shows that the candidate does have a good intuition and thought process. It’s just that he did all of these implicitly on his head.

In consulting case interview, it’s always good to do everything as explicitly as possible. Not only is it easier to follow but it helps show your great thought process.

Understanding Business Analyst Case Interviews

What is a business analyst case interview.

A business analyst case interview is a specialized interview used by companies to evaluate a candidate's ability to analyze and solve business problems. It involves presenting the candidate with a business scenario or problem and asking them to work through the issue to arrive at a logical solution.

This type of interview assesses a range of skills critical to the role of a business analyst, such as analytical thinking, problem solving, and effective communication.

Types of Business Analyst Case Interviews

The most common types of business analyst case interviews include: market sizing, profitability, market entry, mergers & acquisitions, and operations improvement.

1. Market sizing

Market sizing questions require candidates to estimate the size of a particular market. This type of case tests the candidate’s ability to make logical assumptions and perform basic calculations to arrive at a reasonable estimate.

2. Profitability

Profitability cases involve identifying and analyzing the drivers of a company’s profits. Candidates are expected to examine both revenue and cost components and identify potential issues affecting profitability.

3. Market entry

Market entry cases ask candidates to evaluate whether a company should enter a new market. This involves analyzing market potential, competitive landscape, and strategic fit with the company’s existing operations.

4. Mergers & acquisitions

Merger and acquisition cases focus on the evaluation of potential deals between companies. Candidates need to assess the strategic rationale, financial implications, and potential synergies of the merger or acquisition.

5. Operations improvement

Operations improvement cases require candidates to identify inefficiencies in a company’s operations and propose solutions to improve productivity and reduce costs. This involves a deep dive into processes and workflows.

Skills Assessed in a Business Analyst Case Interview

The major skills assessed in a business analyst case interview include: problem solving, analytical thinking, business acumen, and communication.

1. Problem solving

Problem-solving skills are crucial in a business analyst role. Candidates need to demonstrate their ability to identify key issues, break down complex problems, and develop practical solutions.

2. Analytical thinking

Analytical thinking involves the ability to interpret data, identify patterns, and make data-driven decisions. Candidates must show they can analyze information logically and methodically.

3. Business acumen

Business acumen refers to understanding business operations, market dynamics, and strategic considerations. Candidates should display a good grasp of how businesses function and what drives success.

4. Communication

Effective communication is essential for a business analyst. Candidates must articulate their thoughts clearly, present their findings convincingly, and interact professionally with stakeholders.

Preparing for Business Analyst Case Interviews

How to solve business analyst case interviews.

To solve business analyst case interviews, you’ll need to understand the problem, create a framework to break down the problem, develop hypotheses, gather and analyze data, and synthesize findings into a recommendation.

1. Understand the problem

The first step in solving business analyst case interviews is to thoroughly understand the problem. Pay close attention to the problem statement provided by the interviewer and ensure you fully grasp the context and objectives of the case.

If anything is unclear, ask clarifying questions to gather all necessary information and eliminate ambiguities.

2. Create a framework to break down the problem

Next, create a case interview framework to structure your approach. Choose a relevant business framework, such as SWOT analysis, the 4 C’s framework, or Porter’s Five Forces, to organize your analysis. We’ll cover these frameworks later on in this article.

Outline how you will address the problem using the chosen framework, providing a clear roadmap for your analysis.

Breaking down the problem into smaller, manageable components is crucial. Segment the problem and identify key areas that will have the most impact on solving the issue. This systematic approach ensures that you address each part of the problem comprehensively.

3. Develop hypotheses

Developing a case interview hypothesis is the next step. Formulate potential explanations or solutions based on your initial understanding and the available data. Prioritize these hypotheses by determining which to test first based on their likelihood and potential impact.

4. Gather and analyze data

Gather and analyze data methodically. Request any additional data or information you need from the interviewer to test your hypotheses. Perform a detailed analysis, looking for patterns, trends, and insights that support or reject your hypotheses.

5. Synthesize findings into a recommendation

Once you have gathered and analyzed the data, synthesize your findings into a coherent narrative. Summarize the critical insights that will guide your recommendations. Based on your analysis, propose actionable solutions to address the problem, ensuring your recommendations are practical and feasible.

Clear communication is essential. Present your findings articulately, using structured reasoning and a logical flow to make your case. Engage with the interviewer by discussing and defending your recommendations, answering any questions confidently and thoughtfully.

Finally, wrap up your analysis by summarizing your approach, main findings, and recommendations. Highlight the potential impact and benefits of your proposed solutions.

Business Analyst Case Interview Frameworks

Common business analyst case interview frameworks that you should be familiar with include: SWOT analysis, 4 C’s framework, and Porter’s Five Forces.

1. SWOT analysis

SWOT analysis is a strategic planning tool used to evaluate the Strengths, Weaknesses, Opportunities, and Threats related to a business or project. This framework helps you systematically assess both internal and external factors that can impact the success of the business.

• Strengths : These are the internal positive attributes and resources that give the business a competitive advantage. Examples include strong brand reputation, proprietary technology, skilled workforce, and robust financial resources
• Weaknesses : These are the internal negative attributes and limitations that could hinder the business's performance. Examples include poor brand recognition, outdated technology, limited financial resources, and gaps in expertise or capabilities
• Opportunities : These are external factors that the business could exploit to its advantage. They might include market expansion, technological advancements, favorable regulatory changes, or shifts in consumer behavior
• Threats : These are external factors that could pose challenges or risks to the business. Examples include new competitors entering the market, changes in regulations, economic downturns, and shifts in consumer preferences

Using SWOT analysis in a case interview helps you develop a comprehensive understanding of the business’s current position and strategic direction.

2. 4 C’s Framework

The 4 C’s framework is a strategic tool used to analyze a business’s environment and strategic positioning. Each “C” represents a critical area of focus: Customer, Cost, Competition, and Company.

• Customer : This involves understanding the target customer’s needs, preferences, and behaviors. Key aspects include customer demographics, purchasing habits, customer satisfaction, and loyalty. Understanding the customer helps tailor products and services to meet their needs effectively
• Cost : This involves assessing both fixed and variable costs associated with the business. Key aspects include cost structures, cost drivers, economies of scale, and opportunities for cost reduction. Effective cost management is crucial for maintaining profitability and competitiveness
• Competition : This involves analyzing the competitive landscape, including key competitors, their strengths and weaknesses, market share, and competitive strategies. Understanding the competition helps identify market opportunities and threats
• Company : This involves evaluating the internal capabilities, resources, and overall strategy of the company. Key aspects include organizational structure, core competencies, financial health, and strategic objectives. Understanding the company’s internal environment helps in leveraging its strengths and addressing its weaknesses

Using the 4 C’s framework provides a holistic view of the business environment and helps identify key factors that influence business success.

3. Porter’s Five Forces

Porter’s Five Forces is a framework used to analyze the competitive forces within an industry. It helps you understand the dynamics that shape competition and industry profitability. The five forces include:

• Threat of New Entrants : This refers to the potential for new companies to enter the industry and increase competition. Factors to consider include barriers to entry, capital requirements, access to distribution channels, and brand loyalty
• Bargaining Power of Suppliers : This assesses how much power suppliers have to influence prices and terms. Factors to consider include the number of suppliers, availability of substitute inputs, and the importance of the supplier’s product to the industry
• Bargaining Power of Buyers : This evaluates how much power customers have to influence prices and terms. Factors to consider include the number of buyers, availability of substitute products, price sensitivity, and the importance of each buyer to the business
• Threat of Substitute Products or Services : This assesses the likelihood of customers switching to alternative products or services. Factors to consider include the availability of substitutes, their relative price and performance, and the switching costs for customers
• Intensity of Competitive Rivalry : This examines the degree of competition among existing firms in the industry. Factors to consider include the number of competitors, industry growth rate, product differentiation, and exit barriers

Using Porter’s Five Forces provides a comprehensive view of the industry landscape, helping you identify strategic opportunities and threats.

Business Analyst Case Interview Problem Solving Techniques

The major business analyst case interview problem solving techniques you should be familiar with include: breaking down the problem, hypothesis-driven approach, and root cause analysis.

Breaking down the problem

Breaking down a complex problem into smaller, manageable parts is a fundamental problem-solving technique. Start by carefully listening to the problem statement and identifying the main components of the issue. Segment the problem into distinct areas or factors that need to be analyzed.

This approach allows you to tackle each part systematically, ensuring that you don't overlook any critical details. By breaking the problem down, you can also prioritize which areas to focus on first, making your analysis more efficient and thorough.

Hypothesis-driven approach

A hypothesis-driven approach involves formulating potential explanations or solutions based on your initial understanding of the problem. Begin by developing hypotheses that could explain the root cause or potential solution to the issue at hand. Prioritize these hypotheses based on their likelihood and impact.

This method helps you structure your analysis by guiding your data collection and evaluation efforts towards testing these hypotheses. As you gather data, confirm or reject each hypothesis systematically, refining your understanding of the problem and narrowing down the possible solutions.

Root cause analysis

Root cause analysis is a technique used to identify the underlying reasons for a problem rather than just addressing its symptoms. Start by examining the problem in detail and asking questions to uncover the fundamental issues.

Tools such as the "5 Whys" technique, where you repeatedly ask "why" to drill down to the root cause, can be very effective.

Another method is the Fishbone Diagram, or cause-and-effect diagram, which helps visualize the various factors contributing to the problem. Relevant factors may include:

• People : Factors related to human resources or personnel
• Processes : Methods or procedures involved
• Equipment : Tools, machinery, or technology used
• Materials : Raw materials or components involved in production
• Environment : External factors, such as the physical or regulatory environment
• Management : Organizational policies, management practices, or decision-making

By identifying the root cause, you can develop solutions that address the core issue.

Business Analyst Case Interview Tips

1. Practice Regularly

Regular practice with different types of business analyst case interviews is crucial. This helps you become familiar with various business problems and develop your analytical and problem solving skills.

Utilize online resources, case interview books , and mock interviews to expose yourself to a wide range of scenarios. Consistent practice will build your confidence and improve your ability to think on your feet during the actual interview.

2. Develop Critical Thinking Skills

Business analysts are expected to analyze complex problems and propose effective solutions. Develop your critical thinking skills by questioning assumptions, evaluating evidence objectively, and considering alternative perspectives.

Practice thinking strategically and anticipating potential outcomes of different decisions. This skill will help you approach case interviews with a well-rounded and insightful perspective.

3. Understand the Basics

Ensure you have a strong grasp of fundamental business concepts and frameworks. Familiarize yourself with key business analyst frameworks such as SWOT analysis, the 4 C’s framework, and Porter’s Five Forces.

Understanding these basics will help you apply the appropriate framework to structure your analysis effectively. Additionally, stay updated on industry trends and business news to have a broader context for your discussions.

4. Stay Organized

Structure your approach to each case logically and clearly. Begin by outlining your framework and breaking down the problem into manageable components. Use a systematic approach to analyze each part of the problem, ensuring that your analysis is thorough and coherent.

Staying organized not only helps you manage your time effectively but also makes it easier for the interviewer to follow your thought process.

5. Communicate Clearly

Effective communication is essential in case interviews. Articulate your thoughts and solutions clearly and concisely. Avoid jargon and overly complex language. Instead, use simple, straightforward explanations. Engage with the interviewer by asking clarifying questions and summarizing your findings at key points.

Clear communication demonstrates your ability to convey complex ideas in an understandable manner, a critical skill for a business analyst.

6. Seek Feedback

Continuously seek feedback on your performance from peers, mentors, or professional coaches. Constructive feedback helps identify areas for improvement and provides insights into how you can refine your approach. After practicing mock interviews, ask for detailed feedback on your analysis, communication, and overall performance.

Use this feedback to make iterative improvements, focusing on your weak points and honing your strengths.

Mastering Case Study Interview Questions for Business Analysts: Strategies for Success

Case study interview questions are a type of job interview where candidates are presented with a real or simulated business scenario or problem and are asked to analyze, assess, and propose solutions to the situation. These interviews are commonly used to evaluate a candidate’s problem-solving skills, critical thinking abilities, domain knowledge, communication skills, and how well they can apply their skills to real-world business challenges.

Case study interviews are a common component of the hiring process for business analysts. They aim to assess a candidate’s analytical thinking, problem-solving abilities, and decision-making skills in a real-world context.

Case studies for business analysts are scenarios or real-world problems that candidates are presented with during interviews to assess their analytical thinking, problem-solving skills, and ability to make informed decisions. These case studies are designed to simulate the types of challenges and situations that business analysts may encounter in their roles. Case study interviews are important for business analysts for several reasons:

1. Realistic Simulation: Case study interviews provide a realistic simulation of the kind of complex and multifaceted problems that business analysts encounter in their roles. They offer candidates a chance to demonstrate their ability to analyse, think critically, and make informed decisions based on incomplete or ambiguous information.

2. Problem-Solving Skills: Case studies test a candidate’s problem-solving skills. Business analysts often need to analyse various aspects of a problem, break it down into manageable components, identify root causes, and propose effective solutions. Case study interviews assess a candidate’s approach to tackling such challenges.

3. Analytical Thinking: Business analysts need strong analytical thinking skills to dissect problems, gather relevant information, and draw logical conclusions. Case study interviews assess a candidate’s ability to analyse data, identify trends, and make data-driven decisions.

4. Decision-Making: Business analysts often need to make decisions that impact an organization’s strategies, operations, and outcomes. Case study interviews evaluate a candidate’s decision-making skills under pressure and their ability to make well-reasoned choices.

5. Domain Knowledge: Case studies allow candidates to apply their domain knowledge to practical scenarios. This is particularly important for business analysts who work in specialized industries where understanding industry-specific nuances is critical.

6. Prioritization and Time Management: Business analysts  must manage multiple tasks and prioritize their workload. Case study interviews can assess a candidate’s ability to manage time effectively and prioritize tasks based on their significance and urgency.

Overall, case study interviews provide a comprehensive and practical assessment of a candidate’s capabilities as a business analyst, offering valuable insights into their analytical thinking, problem-solving skills, domain expertise, and ability to thrive in challenging work environments.

Sample Case Study Interview Questions

Candidates must use their creativity, analytical thinking, data interpretation, and industry expertise in order to succeed in these interviews. It is crucial for candidates to explain the rationale behind their decisions in addition to how they arrived at their recommendations. Success in case study interviews for business analysts depends on thorough understanding of business principles, effective communication, and structured problem-solving. Following are few sample case studies to help candidates understand the nature of these interviews as well as how to approach such questions.

BCG: Tips And Case Interview Examples

The Boston Consulting Group website  states something very important: the goal of the hiring process is to get to know you better, which means, in the context of Consulting interviews, understanding how you solve problems .

Remember this: in case interviews,  to show how you think is MUCH MORE IMPORTANT than to find an answer to the case .

As a result, you will have case study questions to showcase your problem-solving skills. Likewise, fit interviews have the same purpose: to show what problems you faced and how you resolved them.

253 Case Studies From Business School Case Books

Most of these 253 case study examples are based on case interviews used by consulting firms in real job interviews .

As a result, you can have a good idea of the case study questions you can have when interviewing at these firms .

The Full List Of 253 Free Case Study Examples

• Chicago business school
• Australian Graduate School of Management
• Columbia business school
• Harvard business school
• Wharton business school (2009)
• Wharton busines school (2017)
• Darden business school

Do you want to practice a specific type of case study? Now you can…

I have sorted this list of 253 case studies by type:  profitability, market expansion, industry analysis, pricing, investment or acquisition,  and guesstimates (also known as market sizing questions).

Bonus #1: Know The Types Of Cases You Are Likely To have During Your Interviews

• Profitability cases (29% of cases from that list)
• Investment cases (19% of cases from that list)
• Market sizing questions (15% of cases from that list)

As a result, assuming you’ll have 6 interviews (and therefore 6 case interviews) during the recruitment process:

• “Profitability cases are 29%”  means that chances to have 2 profitability case studies during your recruitment process are very high
• “Investment cases are 19%”  means that chances to have 1 investment case study during your recruitment process are very high.
• “ Guesstimates are 15%”  means that chances of having  1 market sizing question during your recruitment process are high.

Bonus #2: The 10 Cases I Recommend You Doing Now

Over 250 examples of case interviews are a great list, and you may not know where to start.

So, I’ve compiled a list of my 10 favorite case studies.

The 5 case studies I recommend doing if you are a BEGINNER

1. stern case book: drinks gone flat (starting at page 24).

This is a good introduction to a common type of case (declining sales here). I liked the solution presented for this case, particularly how it started by isolating declining sales (what range of products? Volumes or prices, or both?).

2. Stern case book: Sport bar (starting at page 46)

This is an investment case (should you invest in a new bar). Even if the solution presented in this case book is not MECE , it covers the most common quantitative questions you might have in such a case. I recommend doing this case.

3. Stern case book: MJ Wineries (starting at page 85)

This is a profitability case. I liked the solution presented in this case because it illustrates how specific good candidates should be. The case concerns wine, so a good candidate should mention the quality of lands and grapes as important factors.

4. AGSM case book: Piano tuners (starting at page 57)

This is a typical market sizing question. How to answer this type of question is a must-know before going to your interviews.

5. Darden case book: National Logistics (starting at page 49)

Again, this is a very common case (how to reduce costs). I liked the broad range of questions asked in this case, covering key skills assessed by consulting firms during case interviews: brainstorming skills (or creativity), quantitative skills, and business sense.

The 5 case studies I recommend if you are more ADVANCED in your preparation

1. stern: the pricing games (starting at page 55).

This case study asks you to help your client assess different business models. I liked this case because the range of issues to tackle is quite broad.

2. Wharton 2017: Engineer attrition at SLS Oil & Gas Services (starting at page 55)

I liked this case study because the case prompt is uncommon: your client has been facing a very high attrition rate among its population of Engineers. As a result, it’s very unlikely that your solution fits a well-known framework, and you’ll have to demonstrate your problem-solving skills by developing a specific solution.

3. Wharton 2017: Pharma Company Goes International, Outsources Benefits, Integrates New Technology (starting at page 95)

This case is about a client considering outsourcing a part of their activity. Even though I don’t know if this type of case study is very common, I had many case studies like this when I passed my interviews a few years ago. And I always found them difficult!

4. Insead: Gas retail case (starting at page 73)

The question in the problem statement is very broad, making this case difficult. So, only good candidates can have a structured case discussion here.

5. Darden: Fire Proof (starting at page 84)

This is a market entry case. Try to solve it by developing a structure as MECE as possible.

1. The key to landing your consulting job.

A case interview is a core element of the consulting recruitment process at top firms like McKinsey, Bain, and BCG (the “MBB” firms). During a case interview, you will be asked to solve a business case study , which challenges you to think critically and strategically, just like a real consultant. Beyond MBB, firms like LEK, Kearney, Oliver Wyman, and the Big Four (PwC, Deloitte, EY, KPMG) also use case study interviews as a major component of their hiring process.

Why Case Interviews Are Essential

If your goal is to land a role at one of these prestigious consulting firms, you’ll need to master multiple case interviews . These interviews test your ability to think on your feet, structure complex problems, and provide actionable business solutions. Successfully cracking a consulting case interview is a critical step in consulting interview preparation .

The Rise of Online Case Interviews

In addition to traditional face-to-face case interviews , firms are increasingly adopting online case interview formats . Many candidates now face AI-driven case studies or cases delivered by chatbots. These assessments might occur before the actual interview or in tandem with first-round consulting interviews . Knowing how to approach these online assessments is key to staying competitive in today’s consulting interview process .

Why You Need to Prepare Thoroughly for Case Interviews

It’s important to note that case interviews are not something you can approach casually or "wing." Consulting firms explicitly expect candidates to be well-prepared , and many of your competitors will have been practicing for months. Lack of preparation is a major reason why candidates fail. That’s where MCC is here to guide you every step of the way !

What This Guide Will Cover

This guide provides a comprehensive overview of consulting case interviews . You’ll learn everything from how to approach case studies like a consultant to mastering the emerging online case formats .

2. What is a Case Interview?

A case interview simulates real consulting work by having you solve a business case study in conversation with your interviewer. You’ll be tasked with advising a client (an imaginary business or organization) on how to solve a problem or make a decision. Your job is to analyze the provided information and make a final recommendation.

While some business problems may seem straightforward, consulting firms focus on solving complex, unique issues that require creative, non-standard solutions.

Examples of case questions include:

• How much would you pay for a banking license in Ghana?
• Estimate the potential value of the electric vehicle market in Germany.
• How much gas storage capacity should a UK domestic energy supplier build?

Consulting firms seek bright minds to work on these challenging, real-world problems. You’ll need to think outside the box and be prepared for novel solutions during your interview.

2.1. Where Are Case Interviews in the Consulting Selection Process?

Not everyone who applies to a consulting firm will make it to a case interview. In fact, firms eliminate up to 80% of candidates before the interview stage. This is because case interviews are expensive and time-consuming, requiring firms to pull consultants from active projects.

Most candidates are cut based on their resumes and performance in aptitude tests. For example, McKinsey uses its Solve assessment and resumes to eliminate over 70% of applicants before interviews.

Getting to a case interview with a top firm is already an achievement. You’ll need to get through the resume screen, aptitude tests, and possibly other assessments to reach the interview stage.

Let’s take a closer look at the selection process, including application screens, aptitude tests, and interview rounds.

2.1.1. Application Screen

A large portion of candidates are eliminated at the application stage. Resumes and cover letters are often reviewed by a combination of AI tools, recruitment staff, and consulting staff.

To improve your chances, make sure your resume and cover letter are top-notch. Check out our free resume guide and cover letter guide , or consider getting help with editing .

2.1.2. Aptitude Tests and Online Cases

The selection process has been evolving quickly, with firms increasingly using sophisticated online case studies in addition to traditional aptitude tests.

McKinsey now uses an online case as part of its Solve assessment, while BCG’s Casey chatbot directly replaces a live first-round interview. We expect these online cases to become more prevalent in the future, but they are still just simulations of live case interviews.

Whether you’re dealing with an online case or a live interview, your preparation will remain the same. You’ll still need to learn how to solve cases effectively.

2.1.3. Rounds of Interviews

Despite the rise of AI and online cases, live case interviews are still central to consulting selection. Firms will always require live interviews due to the client-facing nature of consulting.

To secure an offer from McKinsey, Bain, BCG, or a similar firm, you’ll need to complete four to six case interviews , typically split across two rounds. Each interview will last approximately 50-60 minutes.

First-round interviews usually consist of two or three case interviews, sometimes accompanied by an online case. If you perform well in the first round, you’ll be invited to a second, more challenging round. After successfully completing up to six case interviews, you may receive an offer.

2.2. Differences between first and second round interviews

Despite case interviews in the first and second round following the same format, second/final round interviews will be significantly more intense . The seniority of the interviewer, time pressure (with up to three interviews back-to-back), and the sheer value of the job at stake will likely make a second round consulting case interview one of the most challenging moments of your professional life.

There are three key differences between the two rounds:

• Time Pressure : Final round case interviews test your ability to perform under pressure, with as many as three interviews in a row and often only very small breaks between them.
• Focus : Since second round interviewers tend to be more senior (usually partners with 12+ years experience) and will be more interested in your personality and ability to handle challenges independently. Some partners will drill down into your experiences and achievements to the extreme. They want to understand how you react to challenges and your ability to identify and learn from past mistakes.
• Psychological Pressure: While case interviews in the first round are usually more focused on you simply cracking the case, second round interviewers often employ a "bad cop" strategy to test the way you react to challenges and uncertainty.

2.3. What skills do case interviews assess?

Reliably impressing your interviewers means knowing what they are looking for. This means understanding the skills you are being assessed against in some detail.

Overall, it’s important always to remember that, with case studies, there are no strict right or wrong answers. What really matters is how you think problems through, how confident you are with your conclusions and how quick you are with the back of the envelope arithmetic.

The objective of this kind of interview isn’t to get to one particular solution, but to assess your skillset. This is even true of modern online cases, where sophisticated AI algorithms score how you work as well as the solutions you generate.

If you visit McKinsey , Bain and BCG web pages on case interviews, you will find that the three firms look for very similar traits, and the same will be true of other top consultancies.

Broadly speaking, your interviewer will be evaluating you across five key areas:

2.1.1.One: Probing mind

Showing intellectual curiosity by asking relevant and insightful questions that demonstrate critical thinking and a proactive nature. For instance, if we are told that revenues for a leading supermarket chain have been declining over the last ten years, a successful candidate would ask:

“ We know revenues have declined. This could be due to price or volume. Do we know how they changed over the same period? ”

This is as opposed to a laundry list of questions like:

• Did customers change their preferences?
• Which segment has shown the decline in volume?
• Is there a price war in the industry?

2.1.2. Structure

Structure in this context means structuring a problem. This, in turn, means creating a framework - that is, a series of clear, sequential steps in order to get to a solution.

As with the case interview in general, the focus with case study structures isn’t on reaching a solution, but on how you get there.

This is the trickiest part of the case interview and the single most common reason candidates fail.

We discuss how to properly structure a case in more detail in section three. In terms of what your interviewer is looking for at high level, though, key pieces of your structure should be:

• Proper understanding of the objective of the case - Ask yourself: "What is the single crucial piece of advice that the client absolutely needs?"
• Identification of the drivers - Ask yourself: "What are the key forces that play a role in defining the outcome?"

Our Problem Driven Structure method, discussed in section three, bakes this approach in at a fundamental level. This is as opposed to the framework-based approach you will find in older case-solving

Focus on going through memorised sequences of steps too-often means failing to develop a full understanding of the case and the real key drivers.

At this link, we run through a case to illustrate the difference between a standard framework-based approach and our Problem Driven Structure method.

2.1.3. Problem Solving

You’ll be tested on your ability to identify problems and drivers, isolate causes and effects, demonstrate creativity and prioritise issues. In particular, the interviewer will look for the following skills:

• Prioritisation - Can you distinguish relevant and irrelevant facts?
• Connecting the dots - Can you connect new facts and evidence to the big picture?
• Establishing conclusions - Can you establish correct conclusions without rushing to inferences not supported by evidence?

2.1.4. Numerical Agility

In case interviews, you are expected to be quick and confident with both precise and approximated numbers. This translates to:

• Performing simple calculations quickly - Essential to solve cases quickly and impress clients with quick estimates and preliminary conclusions.
• Analysing data - Extract data from graphs and charts, elaborate and draw insightful conclusions.
• Solving business problems - Translate a real world case to a mathematical problem and solve it.

Our article on consulting math is a great resource here, though the extensive math content in our MCC Academy is the best and most comprehensive material available.

2.1.5. Communication

Real consulting work isn’t just about the raw analysis to come up with a recommendation - this then needs to be sold to the client as the right course of action.

Similarly, in a case interview, you must be able to turn your answer into a compelling recommendation. This is just as essential to impressing your interviewer as your structure and analysis.

Consultants already comment on how difficult it is to find candidates with the right communication skills. Add to this the current direction of travel, where AI will be able to automate more and more of the routine analytic side of consulting, and communication becomes a bigger and bigger part of what consultants are being paid for.

So, how do you make sure that your recommendations are relevant, smart, and engaging? The answer is to master what is known as CEO-level communication .

This art of speaking like a CEO can be quite challenging, as it often involves presenting information in effectively the opposite way to how you might normally.

To get it right, there are three key areas to focus on in your communications:

• Top down : A CEO wants to hear the key message first. They will only ask for more details if they think that will actually be useful. Always consider what is absolutely critical for the CEO to know, and start with that. You can read more in our article on the Pyramid Principle .
• Concise : This is not the time for "boiling the ocean" or listing an endless number possible solutions. CEOs, and thus consultants, want a structured, quick and concise recommendation for their business problem, that they can implement immediately.
• Fact-based : Consultants share CEOs' hatred of opinions based on gut feel rather than facts. They want recommendations based on facts to make sure they are actually in control. Always go on to back up your conclusions with the relevant facts.

Being concise and to the point is key in many areas, networking being one for them. For more detail on all this, check out our full article on delivering recommendations .

Prep the right way

3. types of case interview.

While most case interviews share a similar structure, firms will have some differences in the particular ways they like to do things in terms of both the case study and the fit component.

As we’ll see, these differences aren’t hugely impactful in terms of how you prepare. That said, it's always good to know as much as possible about what you will be going up against.

3.1. Different case objectives

A guiding thread throughout this article and our approach in general will be to treat each case as a self-contained problem and not try to pigeonhole it into a certain category. Having said that, there are of course similarities between cases and we can identify certain parameters and objectives.

Broadly speaking, cases can be divided into issue-based cases and strategic decision cases. In the former you will be asked to solve a certain issue, such as declining profits, or low productivity whereas in the latter you will be ask whether your client should or should not do something, such as enter a specific market or acquire another company. The chart below is a good breakdown of these different objectives:

3.2. How do interviewers craft cases

While interviewers will very likely be given a case bank to choose from by their company, a good number of them will also choose to adapt the cases they would currently be working on to a case interview setting. The difference is that the latter cases will be harder to pigeonhole and apply standard frameworks to, so a tailored approach will be paramount.

If you’ve applied for a specific practice or type of consulting - such as operational consulting, for example - it’s very likely that you will receive a case geared towards that particular area alongside a ‘generalist’ consulting case (however, if that’s the case, you will generally be notified). The other main distinction when it comes to case interviews is between interviewer-led and candidate-led.

3.3. Candidate-led cases

Most consulting case interview questions test your ability to crack a broad problem, with a case prompt often going something like:

" How much would you pay to secure the rights to run a restaurant in the British Museum? "

You, as a candidate, are then expected to identify your path to solve the case (that is, provide a structure), leveraging your interviewer to collect the data and test your assumptions.

This is known as a “candidate-led” case interview and is used by Bain, BCG and other firms. From a structuring perspective, it’s easier to lose direction in a candidate-led case as there are no sign-posts along the way. As such, you need to come up with an approach that is both broad enough to cover all of the potential drivers in a case but also tailored enough to the problem you are asked to solve. It’s also up to you to figure out when you need to delve deeper into a certain branch of the case, brainstorm or ask for data. The following case from Bain is an excellent example on how to navigate a candidate-led case.

3.4. Interviewer-led cases

This type of case - employed most famously by McKinsey - is slightly different, with the interviewer controlling the pace and direction of the conversation much more than with other case interviews.

At McKinsey, your interviewer will ask you a set of pre-determined questions, regardless of your initial structure. For each question, you will have to understand the problem, come up with a mini structure, ask for additional data (if necessary) and come to the conclusion that answers the question. This more structured format of case also shows up in online cases by other firms - notably including BCG’s Casey chatbot (with the amusing result that practising McKinsey-style cases can be a great addition when prepping for BCG).

Essentially, these interviewer-led case studies are large cases made up of lots of mini-cases. You still use basically the same method as you would for standard (or candidate-led) cases - the main difference is simply that, instead of using that method to solve one big case, you are solving several mini-cases sequentially. These cases are easier to follow as the interviewer will guide you in the right direction. However, this doesn’t mean you should pay less attention to structure and deliver a generic framework! Also, usually (but not always!) the first question will ask you to map your approach and is the equivalent of the structuring question in candidate-led cases. Sometimes, if you’re missing key elements, the interviewer might prompt you in the right direction - so make sure to take those prompts seriously as they are there to help you get back on track (ask for 30 seconds to think on the prompt and structure your approach). Other times - and this is a less fortunate scenario - the interviewer might say nothing and simply move on to the next question. This is why you should put just as much thought (if not more) into the framework you build for interviewer-led cases , as you may be penalized if you produce something too generic or that doesn’t encompass all the issues of the case.

3.5. Case and fit

The standard case interview can be thought of as splitting into two standalone sub-interviews. Thus “case interviews” can be divided into the case study itself and a “fit interview” section, where culture fit questions are asked.

This can lead to a bit of confusion, as the actual case interview component might take up as little as half of your scheduled “case interview”. You need to make sure you are ready for both aspects.

To illustrate, here is the typical case interview timeline:

• First 15-30 minutes: Fit Interview - with questions assessing your motivation to be a consultant in that specific firm and your traits around leadership and teamwork. Learn more about the fit interview in our in-depth article here .
• Next 30-40 minutes: Case Interview - solving a case study
• Last 5 minutes: Fit Interview again - this time focussing on your questions for your interviewer.

Both the Case and Fit interviews play crucial roles in the finial hiring decision. There is no “average” taken between case and fit interviews: if your performance is not up to scratch in either of the two, you will not be able to move on to the next interview round or get an offer.

NB: No case without fit

Note that, even if you have only been told you are having a case interview or otherwise are just doing a case study, always be prepared to answer fit questions. At most firms, it is standard practice to include some fit questions in all case interviews, even if there are also separate explicit fit interviews, and interviewers will almost invariably include some of these questions around your case. This is perfectly natural - imagine how odd and artificial it would be to show up to an interview, simply do a case and leave again, without talking about anything else with the interviewer before or after.

3.5.2. The McKinsey PEI

McKinsey brands its fit aspect of interviews as the Personal Experience Interview or PEI. Despite the different name, this is really much the same interview you will be going up against in Bain, BCG and any similar firms.

McKinsey does have a reputation for pushing candidates a little harder with fit or PEI questions , focusing on one story per interview and drilling down further into the specific details each time. We discuss this tendency more in our fit interview article . However, no top end firm is going to go easy on you and you should absolutely be ready for the same level of grilling at Bain, BCG and others. Thus any difference isn’t hugely salient in terms of prep.

3.6. What is different in 2024?

For the foreseeable future, you are going to have to go through multiple live case interviews to secure any decent consulting job. These might increasingly happen via Zoom rather than in person, but they should remain largely the same otherwise.

However, things are changing and the rise of AI in recent months seems pretty much guaranteed to accelerate existing trends.

Even before the explosive development of AI chatbots like ChatGPT we have seen in recent months, automation was already starting to change the recruitment process.

As we mentioned, case interviews are expensive and inconvenient for firms to run . Ideally, then, firms will try to reduce the number of interviews required for recruitment as far as possible. For many years, tests of various kinds served to cut down the applicant pool and thus the number of interviews. However, these tests had a limited capacity to assess candidates against the full consulting skillset in the way that case interviews do so well.

More recently, though, the development of online testing has allowed for more and more advanced assessments. Top consulting firms have been leveraging screening tests that better and better capture the same skillset as case interviews. Eventually this is converging on automated case studies. We see this very clearly with the addition of the Redrock case to McKinsey’s Solve assessment.

As these digital cases become closer to the real thing, the line between test and case interview blurs. Online cases don’t just reduce the number of candidates to case interview, but start directly replacing them.

Case in point here is BCG’s Casey chatbot . Previously, BCG had deployed less advanced online cases and similar tests to weed out some candidates before live case interviews began. Now, though, Casey actually replaces one first round case interview .

Casey, at time of writing, is still a relatively “basic” chatbot, basically running through a pre-set script. The Whatsapp-like interface does a lot of work to make it feel like one is chatting to a “real person” - the chatbot itself, though, cannot provide feedback or nudges to candidates as would a human interviewer.

We fully expect that, as soon as BCG and other firms can train a truer AI, these online cases will become more widespread and start replacing more live interviews.

We discuss the likely impacts of advanced AI on consulting recruitment and the industry more broadly in our blog.

Here, though, the real message is that you should expect to run into digital cases as well as traditional case interviews .

Luckily, despite any changes in specific case interview format, you will still need to master the same fundamental skills and prepare in much the same way.

We’ll cover a few ways to help prepare for chatbot cases in section four. Ultimately, though, firms are looking for the same problem solving ability and mindset as a real interviewer. Especially as chatbots get better at mimicking a real interviewer, candidates who are well prepared for case cracking in general should have no problem with AI-administered cases.

3.6.1. Automated fit interviews

Analogous to online cases, in recent years there has been a trend towards automated, “one way” fit interviews, with these typically being administered for consultancies by specialist contractors like HireVue or SparkHire.

These are kind of like Zoom interviews, but if the interviewer didn’t show up. Instead you will be given fit questions to answer and must record your answer in your computer webcam. Your response will then go on to be assessed by an algorithm, scoring both what you say and how you say it.

Again, with advances in AI, it is easy to imagine these automated case interviews going from fully scripted interactions, where all candidates are asked the same list of questions, to a more interactive experience. Thus, we might soon arrive at a point where you are being grilled on the details of your stories - McKinsey PEI style - but by a bot rather than a human.

We include some tips on this kind of “one way” fit interview in section six here.

4. How to solve cases with the Problem-Driven Structure?

If you look around online for material on how to solve case studies, a lot of what you find will set out framework-based approaches. However, as we have mentioned, these frameworks tend to break down with more complex, unique cases - with these being exactly the kind of tough case studies you can expect to be given in your case interviews.

To address this problem, the MyConsultingCoach team has synthesized a new approach to case cracking that replicates how top management consultants approach actual engagements.

MyConsultingCoach’s Problem Driven Structure approach is a universal problem solving method that can be applied to any business problem , irrespective of its nature.

As opposed to just selecting a generic framework for each case interview, the Problem Driven Structure approach works by generating a bespoke structure for each individual question and is a simplified version of the roadmap McKinsey consultants use when working on engagements.

The canonical seven steps from McKinsey on real projects are simplified to four for case interview questions, as the analysis required for a six-month engagement is somewhat less than that needed for a 45-minute case study. However, the underlying flow is the same (see the method in action in the video below)

Let's zoom in to see how our method actually works in more detail:

4.1. Identify the problem

Identifying the problem means properly understanding the prompt/question you are given, so you get to the actual point of the case.

This might sound simple, but cases are often very tricky, and many candidates irretrievably mess things up within the first few minutes of starting. Often, they won’t notice this has happened until they are getting to the end of their analysis. Then, they suddenly realise that they have misunderstood the case prompt - and have effectively been answering the wrong question all along!

With no time to go back and start again, there is nothing to do. Even if there were time, making such a silly mistake early on will make a terrible impression on their interviewer, who might well have written them off already. The interview is scuppered and all the candidate’s preparation has been for nothing.

This error is so galling as it is so readily avoidable.

Our method prevents this problem by placing huge emphasis on a full understanding of the case prompt. This lays the foundations for success as, once we have identified the fundamental, underlying problem our client is facing, we focus our whole analysis around finding solutions to this specific issue.

Now, some case interview prompts are easy to digest. For example, “Our client, a supermarket, has seen a decline in profits. How can we bring them up?”. However, many of the prompts given in interviews for top firms are much more difficult and might refer to unfamiliar business areas or industries. For example, “How much would you pay for a banking license in Ghana?” or “What would be your key areas of concern be when setting up an NGO?”

Don’t worry if you have no idea how you might go about tackling some of these prompts!

In our article on identifying the problem and in our full lesson on the subject in our MCC Academy course, we teach a systematic, four step approach to identifying the problem , as well as running through common errors to ensure you start off on the right foot every time!

This is summarised here:

Following this method lets you excel where your competitors mess up and get off to a great start in impressing your interviewer!

4.2. Build your problem driven structure

After you have properly understood the problem, the next step is to successfully crack a case is to draw up a bespoke structure that captures all the unique features of the case.

This is what will guide your analysis through the rest of the case study and is precisely the same method used by real consultants working on real engagements.

Of course, it might be easier here to simply roll out one an old-fashioned framework, and a lot of candidates will do so. This is likely to be faster at this stage and requires a lot less thought than our problem-driven structure approach.

However, whilst our problem driven structure approach requires more work from you, our method has the advantage of actually working in the kind of complex case studies where generic frameworks fail - that is exactly the kind of cases you can expect at an MBB interview .

Since we effectively start from first principles every time, we can tackle any case with the same overarching method. Simple or complex, every case is the same to you and you don’t have to gamble a job on whether a framework will actually work

4.2.1 Issue trees

Issue trees break down the overall problem into a set of smaller problems that you can then solve individually. Representing this on a diagram also makes it easy for both you and your interviewer to keep track of your analysis.

To see how this is done, let’s look at the issue tree below breaking down the revenues of an airline:

These revenues can be segmented as the number of customers multiplied by the average ticket price. The number of customers can be further broken down into a number of flights multiplied by the number of seats, times average occupancy rate. The node corresponding to the average ticket price can then be segmented further.

4.2.2 Hypothesis trees

Hypothesis trees are similar, the only difference being that rather than just trying to break up the issue into smaller issues you are assuming that the problem can be solved and you are formulating solutions.

In the example above, you would assume revenues can be increased by either increasing the average ticket price or the number of customers . You can then hypothesize that you can increase the average occupancy rate in three ways: align the schedule of short and long haul flights, run a promotion to boost occupancy in off-peak times, or offer early bird discounts.

4.2.3 Other structures:structured lists

Structured lists are simply subcategories of a problem into which you can fit similar elements. This McKinsey case answer starts off by identifying several buckets such as retailer response, competitor response, current capabilities and brand image and then proceeds to consider what could fit into these categories.

Buckets can be a good way to start the structure of a complex case but when using them it can be very difficult to be MECE and consistent, so you should always aim to then re-organize them into either an issue or a hypothesis tree.

It is worth noting that the same problem can be structured in multiple valid ways by choosing different means to segment the key issues. Ultimately all these lists are methods to set out a logical hierachy among elements.

4.2.4 Structures in practice

That said, not all valid structures are equally useful in solving the underlying problem. A good structure fulfils several requirements - including MECE-ness , level consistency, materiality, simplicity, and actionability. It’s important to put in the time to master segmentation, so you can choose a scheme isn’t only valid, but actually useful in addressing the problem.

After taking the effort to identify the problem properly, an advantage of our method is that it will help ensure you stay focused on that same fundamental problem throughout. This might not sound like much, but many candidates end up getting lost in their own analysis, veering off on huge tangents and returning with an answer to a question they weren’t asked.

Another frequent issue - particularly with certain frameworks - is that candidates finish their analysis and, even if they have successfully stuck to the initial question, they have not actually reached a definite solution. Instead, they might simply have generated a laundry list of pros and cons, with no clear single recommendation for action.

Clients employ consultants for actionable answers, and this is what is expected in the case interview. The problem driven structure excels in ensuring that everything you do is clearly related back to the key question in a way that will generate a definitive answer. Thus, the problem driven structure builds in the hypothesis driven approach so characteristic of real consulting practice.

You can learn how to set out your own problem driven structures in our article here and in our full lesson in the MCC Academy course.

4.2. Lead the analysis

A problem driven structure might ensure we reach a proper solution eventually, but how do we actually get there?

We call this step " leading the analysis ", and it is the process whereby you systematically navigate through your structure, identifying the key factors driving the issue you are addressing.

Generally, this will mean continuing to grow your tree diagram, further segmenting what you identify as the most salient end nodes and thus drilling down into the most crucial factors causing the client’s central problem.

Once you have gotten right down into the detail of what is actually causing the company’s issues, solutions can then be generated quite straightforwardly.

To see this process in action, we can return to our airline revenue example:

Let’s say we discover the average ticket price to be a key issue in the airline’s problems. Looking closer at the drivers of average ticket price, we find that the problem lies with economy class ticket prices. We can then further segment that price into the base fare and additional items such as food.

Having broken down the issue to such a fine-grained level and considering the 80/20 rule(see below), solutions occur quite naturally. In this case, we can suggest incentivising the crew to increase onboard sales, improving assortment in the plane, or offering discounts for online purchases.

Our article on leading the analysis is a great primer on the subject, with our video lesson in the MCC Academy providing the most comprehensive guide available.

4.4. Provide recommendations

So you have a solution - but you aren’t finished yet!

Now, you need to deliver your solution as a final recommendation.

This should be done as if you are briefing a busy CEO and thus should be a one minute, top-down, concise, structured, clear, and fact-based account of your findings.

The brevity of the final recommendation belies its importance. In real life consulting, the recommendation is what the client has potentially paid millions for - from their point of view, it is the only thing that matters.

In a case interview, your performance in this final summing up of your case is going to significantly colour your interviewer’s parting impression of you - and thus your chances of getting hired!

So, how do we do it right?

Barbara Minto's Pyramid Principle elegantly sums up almost everything required for a perfect recommendation. The answer comes first , as this is what is most important. This is then supported by a few key arguments , which are in turn buttressed by supporting facts .

Across the whole recommendation, the goal isn’t to just summarise what you have done. Instead, you are aiming to synthesize your findings to extract the key "so what?" insight that is useful to the client going forward.

All this might seem like common sense, but it is actually the opposite of how we relay results in academia and other fields. There, we typically move from data, through arguments and eventually to conclusions. As such, making good recommendations is a skill that takes practice to master.

We can see the Pyramid Principle illustrated in the diagram below:

To supplement the basic Pyramid Principle scheme, we suggest candidates add a few brief remarks on potential risks and suggested next steps . This helps demonstrate the ability for critical self-reflection and lets your interviewer see you going the extra mile.

The combination of logical rigour and communication skills that is so definitive of consulting is particularly on display in the final recommendation.

Despite it only lasting 60 seconds, you will need to leverage a full set of key consulting skills to deliver a really excellent recommendation and leave your interviewer with a good final impression of your case solving abilities.

Our specific article on final recommendations and the specific video lesson on the same topic within our MCC Academy are great, comprehensive resources. Beyond those, our lesson on consulting thinking and our articles on MECE and the Pyramid Principle are also very useful.

4.5. What if I get stuck?

Naturally with case interviews being difficult problems there may be times where you’re unsure what to do or which direction to take. The most common scenario is that you will get stuck midway through the case and there are essentially two things that you should do:

• 1. Go back to your structure
• 2. Ask the interviewer for clarification

Your structure should always be your best friend - after all, this is why you put so much thought and effort into it: if it’s MECE it will point you in the right direction. This may seem abstract but let’s take the very simple example of a profitability case interview: if you’ve started your analysis by segmenting profit into revenue minus costs and you’ve seen that the cost side of the analysis is leading you nowhere, you can be certain that the declining profit is due to a decline in revenue.

Similarly, when you’re stuck on the quantitative section of the case interview, make sure that your framework for calculations is set up correctly (you can confirm this with the interviewer) and see what it is you’re trying to solve for: for example if you’re trying to find what price the client should sell their new t-shirt in order to break even on their investment, you should realize that what you’re trying to find is the break even point, so you can start by calculating either the costs or the revenues. You have all the data for the costs side and you know they’re trying to sell 10.000 pairs so you can simply set up the equation with x being the price.

As we’ve emphasised on several occasions, your case interview will be a dialogue. As such, if you don’t know what to do next or don’t understand something, make sure to ask the interviewer (and as a general rule always follow their prompts as they are trying to help, not trick you). This is especially true for the quantitative questions, where you should really understand what data you’re looking at before you jump into any calculations. Ideally you should ask your questions before you take time to formulate your approach but don’t be afraid to ask for further clarification if you really can’t make sense of what’s going on. It’s always good to walk your interviewer through your approach before you start doing the calculations and it’s no mistake to make sure that you both have the same understanding of the data. For example when confronted with the chart below, you might ask what GW (in this case gigawatt) means from the get-go and ask to confirm the different metrics (i.e. whether 1 GW = 1000 megawatts). You will never be penalised for asking a question like that.

5. Inside the Consultant’s Mind: Tools to Crack Consulting Cases

If you’re new to case cracking, it’s easy to feel overwhelmed when faced with a complex case question, unsure of where to begin.

Fortunately, like chess, the basic rules of solving cases are straightforward. Our problem-driven structure provides a clear, high-level framework to guide you. However, just like becoming a chess master, true proficiency in case interviews comes from understanding the nuances and building your skills through time and practice.

Beyond the approach, there are additional strategies and insights that consultants use, which can give you an edge. In this section, we’ll provide an overview of the core concepts you need to know, while linking to in-depth resources that will help you dive deeper into each topic.

5.1. An overall clear structure

Consultants thrive on structure, and this is one of the most important aspects to keep in mind during case interviews. Not only is it a key evaluation criterion, but it’s also the greatest tool at your disposal for tackling complex cases. Let’s break down the areas where a clear structure will make all the difference.

5.1.1 Structured notes

Every case interview begins with a prompt, and your ability to take clear, concise, and structured notes is crucial. These notes should help you repeat the case back to the interviewer, without including unnecessary information.

A good approach is to divide your notes into sections for:

• The case brief
• Follow-up questions and answers
• Numerical data
• Case structure (crucial for solving the case)
• Scrap work (usually for calculations)

As you work through the case, keep feeding and integrating your structure to maintain a high-level view of the case and avoid losing focus. This is especially important in interviewer-led cases, where you might want separate sheets for each question.

5.1.2 Structured communication

There are three main types of communication in case interviews:

• 1. Asking and answering questions
• 2. Walking the interviewer through your structure
• 3. Delivering your recommendation

When asking questions, always take a moment to organize your thoughts. Numbering your questions and answers helps ensure clarity. The same goes for walking the interviewer through your structure—use a numbering system to outline your approach clearly.

Finally, when delivering your recommendation, use a top-down approach. Circle or mark key facts throughout the case so they’re easily accessible when needed.

5.1.3 Structured framework

Having a systematic approach or framework for every case is essential. There’s a key difference between applying a problem-solving framework and forcing a case into a predetermined one. The former is necessary, while the latter can be harmful.

Whether using buckets or issue trees, ensure your framework is clearly outlined. Keeping it on a separate sheet or alongside the case prompt helps you stay organized and focused on the solution.

5.1.4 Structured calculations

When you encounter numerical data, take your time and plan your calculations before diving in. Interviewers value your logic and approach more than raw speed. Before starting, write down the steps you need to perform the calculation. Here’s an example:

• 1. Calculate current profits: Profits = Revenues - (Variable costs + Fixed costs)
• 2. Calculate the reduction in variable costs: Variable costs x 0.9
• 3. Calculate new profits: New profits = Revenues - (New variable costs + Fixed costs)

Make sure to demonstrate a structured approach before executing the calculations on a scrap sheet, then fill in the final results.

5.2. Common business knowledge and formulas

Although some consulting firms claim they don’t evaluate candidates based on their business knowledge, familiarity with basic business concepts and formulae is very useful in terms of understanding the case studies you are given in the first instance and drawing inspiration for structuring and brainstorming.

If you are coming from a business undergrad, an MBA or are an experienced hire, you might well have this covered already. For those coming from a different background, it may be useful to cover some.

Luckily, you don’t need a degree-level understanding of business to crack case interviews , and a lot of the information you will pick up by osmosis as you read through articles like this and go through cases.

However, some things you will just need to sit down and learn. We cover everything you need to know in some detail in our Case Academy Course course. However, some examples here of things you need to learn are:

• Basic accounting (particularly how to understand all the elements of a balance sheet)
• Basic economics
• Basic marketing
• Basic strategy

Below we include a few elementary concepts and formulae so you can hit the ground running in solving cases. We should note that you should not memorise these and indeed a good portion of them can be worked out logically, but you should have at least some idea of what to expect as this will make you faster and will free up much of your mental computing power. In what follows we’ll tackle concepts that you will encounter in the private business sector as well as some situations that come up in cases that feature clients from the NGO or governmental sector.

5.2.1 Business sector concepts

These concepts are the bread and butter of almost any business case so you need to make sure you have them down. Naturally, there will be specificities and differences between cases but for the most part here is a breakdown of each of them.

5.2.1.1. Revenue

The revenue is the money that the company brings in and is usually equal to the number of products they sell multiplied to the price per item and can be expressed with the following equation:

Revenue = Volume x Price

Companies may have various sources of revenue or indeed multiple types of products, all priced differently which is something you will need to account for in your case interview. Let’s consider some situations. A clothing company such as Nike will derive most of their revenue from the number of products they sell times the average price per item. Conversely, for a retail bank revenue is measured as the volume of loans multiplied by the interest rate at which the loans are given out. As we’ll see below, we might consider primary revenues and ancillary revenues: in the case of a football club, we might calculate primary revenues by multiplying the number of tickets sold by the average ticket price, and ancillary revenues those coming from sales of merchandise (similarly, let’s say average t-shirt price times the number of t-shirts sold), tv rights and sponsorships.

These are but a few examples and another reminder that you should always aim to ask questions and understand the precise revenue structure of the companies you encounter in cases.

5.2.1.2. Costs

The costs are the expenses that a company incurs during its operations. Generally, they can be broken down into fixed and variable costs :

Costs = Fixed Costs + Variable Costs

As their name implies, fixed costs do not change based on the number of units produced or sold. For example, if you produce shoes and are renting the space for your factory, you will have to pay the rent regardless of whether you produce one pair or 100. On the other hand, variable costs depend on the level of activity, so in our shoe factory example they would be equivalent to the materials used to produce each pair of shoes and would increase the more we produce.

These concepts are of course guidelines used in order to simplify the analysis in cases, and you should be aware that in reality often the situation can be more complicated. However, this should be enough for case interviews. Costs can also be quasi-fixed, in that they increase marginally with volume. Take the example of a restaurant which has a regular staff, incurring a fixed cost but during very busy hours or periods they also employ some part-time workers. This cost is not exactly variable (as it doesn’t increase with the quantity of food produced) but also not entirely fixed, as the number of extra hands will depend on how busy the restaurant is. Fixed costs can also be non-linear in nature. Let’s consider the rent in the same restaurant: we would normally pay a fixed amount every month, but if the restaurant becomes very popular we might need to rent out some extra space so the cost will increase. Again, this is not always relevant for case interviews.

5.2.1.3. Profit and profit margin

The profit is the amount of money a company is left with after it has paid all of its expenses and can be expressed as follows:

Profit = Revenue - Costs

It’s very likely that you will encounter a profitability issue in one of your case interviews, namely you will be asked to increase a company’s profit. There are two main ways of doing this: increasing revenues and reducing costs , so these will be the two main areas you will have to investigate. This may seem simple but what you will really need to understand in a case are the key drivers of a business (and this should be done through clarifying questions to the interviewer - just as a real consultant would question their client).

For example, if your client is an airline you can assume that the main source of revenue is sales of tickets, but you should inquire how many types of ticket the specific airline sells. You may naturally consider economy and business class tickets, but you may find out that there is a more premium option - such as first class - and several in-between options. Similarly to our football club example, there may be ancillary revenues from selling of food and beverage as well as advertising certain products or services on flights.

You may also come across the profit margin in case interviews. This is simply the percentage of profit compared to the revenue and can be expressed as follows:

Profit margin = Profit/Revenue x 100

5.2.1.4. Break-even point

An ancillary concept to profit, the break-even point is the moment where revenues equal costs making the profit zero and can be expressed as the following equation:

Revenues = Costs (Fixed costs + Variable costs)

This formula will be useful when you are asked questions such as ‘What is the minimum price I should sell product X?’ or ‘What quantity do I need to sell in order to recoup my investment?’. Let’s say in a case interview an owner of a sandwich store asks us to figure out how many salami and cheese salami sandwiches she needs to sell in order to break even. She’s spending $4 on salami and $2 for cheese and lettuce per sandwich, and believes she can sell the sandwiches at around $7. The cost of utilities and personnel is around $5000 per month. We could lay this all out in the break-even equation:

7 x Q ( quantity ) = (4+2) x Q + 5000 ( variable + fixed costs )

In a different scenario, we may be asked to calculate the break-even price . Let’s consider our sandwich example and say our owner knows she has enough ingredients for about 5000 sandwiches per month but is not sure how much to sell them for. In that case, if we know our break-even equation, we can simply make the following changes:

P ( price ) x 5000 = (4+2) x 5000 + 5000

By solving the equation we get to the price of $7 per sandwich.

5.2.1.5. Market share and market size

We can also consider the market closely with profit, as in fact the company’s performance in the market is what drives profits. The market size is the total number of potential customers for a certain business or product, whereas the market share is the percentage of that market that your business controls (or could control, depending on the case).

There is a good chance you will have to estimate the market size in one of your case interviews and we get into more details on how to do that below. You may be asked to estimate this in either number of potential customers or total value . The latter simply refers to the number of customers multiplied by the average value of the product or service.

To calculate the market share you will have to divide the company’s share by the total market size and multiply by 100:

Note, though, that learning the very basics of business is the beginning rather than the end of your journey. Once you are able to “speak business” at a rudimentary level, you should try to “become fluent” and immerse yourself in reading/viewing/listening to as wide a variety of business material as possible, getting a feel for all kinds of companies and industries - and especially the kinds of problems that can come up in each context and how they are solved. The material put out by the consulting firms themselves is a great place to start, but you should also follow the business news and find out about different companies and sectors as much as possible between now and interviews. Remember, if you’re going to be a consultant, this should be fun rather than a chore!

5.3 Public sector and NGO concepts

As we mentioned, there will be some cases (see section 6.6 for a more detailed example) where the key performance indicators (or KPIs in short) will not be connected to profit. The most common ones will involve the government of a country or an NGO, but they can be way more diverse and require more thought and application of first principles. We have laid out a couple of the key concepts or KPIs that come up below

5.3.1 Quantifiability

In many such scenarios you will be asked to make an important strategic decision of some kind or to optimise a process. Of course these are not restricted to non-private sector cases but this is where they really come into their own as there can be great variation in the type of decision and the types of field.

While there may be no familiar business concepts to anchor yourself onto, a concept that is essential is quantifiability . This means, however qualitative the decision might seem, consultants rely on data so you should always aim to have aspects of a decision that can be quantified, even if the data doesn’t present itself in a straightforward manner.

Let’s take a practical example. Your younger sibling asks you to help them decide which university they should choose if they want to study engineering. One way to structure your approach would be to segment the problem into factors affecting your sibling’s experience at university and experience post-university. Within the ‘at uni’ category you might think about the following:

• Financials : How much are tuition costs and accommodation costs?
• Quality of teaching and research : How are possible universities ranked in the QS guide based on teaching and research?
• Quality of resources : How well stocked is their library, are the labs well equipped etc.?
• Subject ranking : How is engineering at different unis ranked?
• Life on campus and the city : What are the living costs in the city where the university is based? What are the extracurricular opportunities and would your sibling like to live in that specific city based on them?

Within the ‘out of uni’ category you might think about:

• Exit options : What are the fields in which your sibling could be employed and how long does it take the average student of that university to find a job?
• Alumni network : What percentage of alumni are employed by major companies?
• Signal : What percentage of applicants from the university get an interview in major engineering companies and related technical fields?

You will perhaps notice that all the buckets discussed pose quantifiable questions meant to provide us with data necessary to make a decision. It’s no point to ask ‘Which university has the nicest teaching staff?’ as that can be a very subjective metric.

5.3.1 Impact

Another key concept to consider when dealing with sectors other than the private one is how impactful a decision or a line of inquiry is on the overarching issue , or whether all our branches in our issue tree have a similar impact. This can often come in the form of impact on lives, such as in McKinsey’s conservation case discussed below, namely how many species can we save with our choice of habitat.

5.4 Common consulting concepts

Consultants use basic logic business on an every day basis, as they help them articulate their frameworks to problems. However, they also use some consulting specific logical principles to quality check their analysis and perform in the most efficient way possible. These principles can be applied to all aspects of a consultant’s work, but for brevity we can say they mostly impact a consultant’s systematic approach and communication - two very important things that are also tested in case interviews. Therefore, it’s imperative that you not only get to know them, but learn how and when to use them as they are at the very core of good casing. They are MECE-ness, the Pareto Principle and the Pyramid principle and are explained briefly below - you should, however, go on to study them in-depth in their respective articles.

Perhaps the central pillar of all consulting work and an invaluable tool to solve cases, MECE stands for Mutually Exclusive and Collectively Exhaustive . It can refer to any and every aspect in a case but is most often used when talking about structure. We have a detailed article explaining the concept here , but the short version is that MECE-ness ensures that there is no overlap between elements of a structure (i.e. the Mutually Exclusive component) and that it covers all the drivers or areas of a problem (Collectively Exhaustive). It is a concept that can be applied to any segmentation when dividing a set into subsets that include it wholly but do not overlap.

Let’s take a simple example and then a case framework example. In simple terms, when we are asked to break down the set ‘cars’ into subsets, dividing cars into ‘red cars’ and ‘sports cars’ is neither mutually exclusive (as there are indeed red sports cars) nor exhaustive of the whole set (i.e. there are also yellow non-sports cars that are not covered by this segmentation). A MECE way to segment would be ‘cars produced before 2000’ and ‘cars produced after 2000’ as this segmentation allows for no overlap and covers all the cars in existence.

Dividing cars can be simple, but how can we ensure MECEness in a case-interview a.k.a. a business situation. While the same principles apply, a good tip to ensure that your structure is MECE is to think about all the stakeholders - i.e. those whom a specific venture involves.

Let’s consider that our client is a soda manufacturer who wants to move from a business-to-business strategy, i.e. selling to large chains of stores and supermarkets, to a business-to-consumer strategy where it sells directly to consumers. In doing so they would like to retrain part of their account managers as direct salespeople and need to know what factors to consider.

A stakeholder-driven approach would be to consider the workforce and customers and move further down the issue tree, thinking about individual issues that might affect them. In the case of the workforce, we might consider how the shift would affect their workload and whether it takes their skillset into account. As for the customers, we might wonder whether existing customers would be satisfied with this move: will the remaining B2B account managers be able to provide for the needs of all their clients and will the fact that the company is selling directly to consumers now not cannibalise their businesses? We see how by taking a stakeholder-centred approach we can ensure that every single perspective and potential issue arising from it is fully covered.

5.4.2 The Pareto Principle

Also known as the 80/20 rule, this principle is important when gauging the impact of a decision or a factor in your analysis. It simply states that in business (but not only) 80% of outcomes come from 20% of causes. What this means is you can make a few significant changes that will impact most of your business organisation, sales model, cost structure etc.

Let’s have a look at 3 quick examples to illustrate this:

• 80% of all accidents are caused by 20% of drivers
• 20% of a company’s products account for 80% of the sales
• 80% of all results in a company are driven by 20% of its employees

The 80/20 rule will be a very good guide line in real engagements as well as case interviews, as it will essentially point to the easiest and most straightforward way of doing things. Let’s say one of the questions in a case is asking you to come up with an approach to understand the appeal of a new beard trimmer. Obviously you can’t interview the whole male population so you might think about setting up a webpage and asking people to comment their thoughts. But what you would get would be a laundry list of difficult to sift through data.

Using an 80/20 approach you would segment the population based on critical factors (age groups, grooming habits etc.) and then approach a significant sample size of each (e.g. 20), analysing the data and reaching a conclusion.

5.4.3 The Pyramid Principle

This principle refers to organising your communication in a top-down , efficient manner. While this is generally applicable, the pyramid principle will most often be employed when delivering the final recommendation to your client. This means - as is implicit in the name - that you would organise your recommendation (and communication in general) as a pyramid, stating the conclusion or most important element at the top then go down the pyramid listing 3 supporting arguments and then further (ideally also 3) supporting arguments for those supporting arguments.

Let’s look at this in practice in a case interview context: your client is a German air-conditioning unit manufacturer who was looking to expand into the French market. However, after your analysis you’ve determined that the market share they were looking to capture would not be feasible. A final recommendation using the Pyramid Principle would sound something like this: ‘I recommend that we do not enter the German market for the following three reasons. Firstly, the market is too small for our ambitions of $50 million. Secondly the market is heavily concentrated, being controlled by three major players and our 5 year goal would amount to controlling 25% of the market, a share larger than that of any of the players. Thirdly, the alternative of going into the corporate market would not be feasible, as it has high barriers to entry.Then, if needed, we could delve deeper into each of our categories

6. Building blocks

As we mentioned before, in your case interview preparation you will undoubtedly find preparation resources that claim that there are several standard types of cases and that there is a general framework that can be applied to each type of case. While there are indeed cases that are straightforward at least in appearance and seemingly invite the application of such frameworks, the reality is never that simple and cases often involve multiple or more complicated components that cannot be fitted into a simple framework.

At MCC we don’t want you to get into the habit of trying to identify which case type you’re dealing with and pull out a framework, but we do recognize that there are recurring elements in frameworks that are useful - such as the profitability of a venture (with its revenues and costs), the valuation of a business, estimating and segmenting a market and pricing a product.

We call these building blocks because they can be used to build case frameworks but are not a framework in and of themselves, and they can be shuffled around and rearranged in any way necessary to be tailored to our case. Hence, our approach is not to make you think in terms of case types but work from first principles and use these building blocks to build your own framework. Let’s take two case prompts to illustrate our point.

Bain Case Study Example

The first is from the Bain website, where the candidate is asked whether they think it’s a good idea for their friend to open a coffee shop in Cambridge UK (see the case here ). The answer framework provided here is a very straightforward profitability analysis framework, examining the potential revenues and potential costs of the venture:

While this is a good point to start for your case interview (especially taken together with the clarifying questions), we will notice that this approach will need more tailoring to the case - for example the quantity of coffee will be determined by the market for coffee drinkers in Cambridge, which we have to determine based on preference. We are in England so a lot of people will be drinking tea but we are in a university town so perhaps more people than average are drinking coffee as it provides a better boost when studying. All these are some much needed case-tailored hypotheses that we can make based on the initial approach.

Just by looking at this case we might be tempted to say that we can just take a profitability case and apply it without any issues. However, this generic framework is just a starting point and in reality we would need to tailor it much further in the way we had started to do in order to get to a satisfactory answer. For example, the framework for this specific case interview doesn’t cover aspects such as the customer’s expertise: does the friend have any knowledge of the coffee business, such as where to source coffee and how to prepare it? Also, we could argue there may be some legal factors to consider here, such as any approvals that they might need from the city council to run a coffee shop on site, or some specific trade licences that are not really covered in the basic profitability framework.

McKinsey Case Study Example

Let’s take a different case , however, from the McKinsey website. In this scenario, the candidate is being asked to identify some factors in order to choose where to focus the client’s conservation efforts. Immediately we can realise that this case doesn’t lend itself to any pre-packaged framework and we will need to come up with something from scratch - and take a look at McKinsey’s answer of the areas to focus on:

We notice immediately that this framework is 100% tailored to the case - of course there are elements which we encounter in other cases, such as costs and risks but again these are applied in an organic way. It’s pretty clear that while no standard framework would work in this case, the aforementioned concepts - costs and risks - and the way to approach them (a.k.a building blocks ) are fundamentally similar throughout cases (with the obvious specificities of each case).

In what follows, we’ll give a brief description of each building block starting from the Bain example discussed previously, in order to give you a general idea of what they are and their adaptability, but you should make sure to follow the link to the in-depth articles to learn all their ins and outs.

6.1 Estimates and segmentation

This building block will come into play mostly when you’re thinking about the market for a certain product (but make sure to read the full article for more details). Let’s take our Bain Cambridge coffee example. As we mentioned under the quantity bucket we need to understand what the market size for coffee in Cambridge would be - so we can make an estimation based on segmentation .

The key to a good estimation is the ability to logically break down the problem into more manageable pieces. This will generally mean segmenting a wider population to find a particular target group. We can start off with the population of Cambridge - which we estimate at 100.000. In reality the population is closer to 150.000 but that doesn’t matter - the estimation has to be reasonable and not accurate , so unless the interviewer gives you a reason to reconsider you can follow your instinct. We can divide that into people who do and don’t drink coffee. Given our arguments before, we can conclude that 80% of those, so 80.000 drink coffee. Then we can further segment into those who drink regularly - let’s say every day - and those who drink occasionally - let’s say once a week. Based on the assumptions before about the student population needing coffee to function, and with Cambridge having a high student population, we can assume that 80% of those drinking coffee are regular drinkers, so that would be 64.000 regular drinkers and 16.000 occasional drinkers. We can then decide whom we want to target what our strategy needs to be:

This type of estimation and segmentation can be applied to any case specifics - hence why it is a building block.

6.2 Profitability

We had several looks at this building block so far (see an in-depth look here ) as it will show up in most case interivew scenarios, since profit is a key element in any company’s strategy. As we have seen, the starting point to this analysis is to consider both the costs and revenues of a company, and try to determine whether revenues need to be improved or whether costs need to be lowered. In the coffee example, the revenues are dictated by the average price per coffe x the number of coffees sold , whereas costs can be split into fixed and variable .

Some examples of fixed costs would be the rent for the stores and the cost of the personnel and utilities, while the most obvious variable costs would be the coffee beans used and the takeaway containers (when needed). We may further split revenues in this case into Main revenues - i.e. the sales of coffee - and Ancillary revenues , which can be divided into Sales of food products (sales of pastries, sandwiches etc., each with the same price x quantity schema) and Revenues from events - i.e renting out the coffee shop to events and catering for the events themselves. Bear in mind that revenues will be heavily influenced by the penetration rate , i.e. the share of the market which we can capture.

6.3 Pricing

Helping a company determine how much they should charge for their goods or services is another theme that comes up frequently in cases. While it may seem less complicated than the other building blocks, we assure you it’s not - you will have to understand and consider several factors, such as the costs a company is incurring, their general strategic positioning, availability, market trends as well as the customers’ willingness to pay (or WTP in short) - so make sure to check out our in-depth guide here .

In our example, we may determine that the cost per cup (coffee beans, staff, rent) is £1. We want to be student friendly so we should consider how much students would want to pay for a coffee as well as how much are competitors are charging. Based on those factors, it would be reasonable to charge on average £2 per cup of coffee. It’s true that our competitors are charging £3 but they are targeting mostly the adult market, whose willingness to pay is higher, so their pricing model takes that into account as well as the lower volume of customers in that demographic.

6.4. Valuation

A variant of the pricing building block, a valuation problem generally asks the candidate to determine how much a client should pay for a specific company (the target of an acquisition) as well as what other factors to consider. The two most important factors (but not the only ones - for a comprehensive review see our Valuation article ) to consider are the net present value (in consulting interviews usually in perpetuity) and the synergies .

In short, the net present value of a company is how much profit it currently brings in, divided by how much that cash flow will depreciate in the future and can be represented with the equation below:

The synergies refer to what could be achieved should the companies operate as one, and can be divided into cost and revenue synergies .

Let’s expand our coffee example a bit to understand these. Imagine that our friend manages to open a chain of coffee shops in Cambridge and in the future considers acquiring a chain of take-out restaurants. The most straightforward example of revenue synergies would be cross-selling, in this case selling coffee in the restaurants as well as in the dedicated stores, and thus getting an immediate boost in market share by using the existing customers of the restaurant chain. A cost synergy would be merging the delivery services of the two businesses to deliver both food and coffee, thus avoiding redundancies and reducing costs associated with twice the number of drivers and vehicles.

6.5. Competitive interaction

This component of cases deals with situations where the market in which a company is operating changes and the company must decide what to do. These changes often have to do with a new player entering the market (again for more details make sure to dive into the Competitive Interaction article ).

Let’s assume that our Cambridge coffee shop has now become a chain and has flagged up to other competitors that Cambridge is a blooming market for coffee. As such, Starbucks has decided to open a few stores in Cambridge themselves, to test this market. The question which might be posed to a candidate is what should our coffee chain do. One way (and a MECE one) to approach the problem is to decide between doing something and doing nothing . We might consider merging with another coffee chain and pooling our resources or playing to our strengths and repositioning ourselves as ‘your student-friendly, shop around the corner’. Just as easily we may just wait the situation out and see whether indeed Starbucks is cutting into our market share - after all, the advantages of our product and services might speak for themselves and Starbucks might end up tanking. Both of these are viable options if argued right and depending on the further specifics of the case.

6.6. Special cases

Most cases deal with private sectors, where the overarching objective entails profit in some form. However, as hinted before, there are cases which deal with other sectors where there are other KPIs in place . The former will usually contain one or several of these building blocks whereas the latter will very likely have neither. This latter category is arguably the one that will stretch your analytical and organisational skills to the limit, since there will be very little familiarity that you can fall back on (McKinsey famously employs such cases in their interview process).

So how do we tackle the structure for such cases? The short answer would be starting from first principles and using the problem driven structure outlined above, but let’s look at a quick example in the form of a McKinsey case :

The first question addressed to the candidate is the following:

This is in fact asking us to build a structure for the case. So what should we have in mind here? Most importantly, we should start with a structure that is MECE and we should remember to do that by considering all the stakeholders . They are on the one hand the government and affiliated institutions and on the other the population. We might then consider which issues might arise for each shareholder and what the benefits for them would be, as well as the risks. This approach is illustrated in the answer McKinsey provides as well:

More than anything, this type of case shows us how important it is to practise and build different types of structures, and think about MECE ways of segmenting the problem.

7. How Do I prepare for case interviews

In consulting fashion, the overall preparation can be structured into theoretical preparation and practical preparation , with each category then being subdivided into individual prep and prep with a partner .

As a general rule, the level and intensity of the preparation will differ based on your background - naturally if you have a business background (and have been part of a consulting club or something similar) your preparation will be less intensive than if you’re starting from scratch. The way we suggest you go about it is to start with theoretical preparation , which means learning about case interviews, business and basic consulting concepts (you can do this using free resources - such as the ones we provide - or if you want a more through preparation you can consider joining our Case Academy as well).

You can then move on to the practical preparation which should start with doing solo cases and focusing on areas of improvement, and then move on to preparation with a partner , which should be another candidate or - ideally - an ex-consultant.

Let’s go into more details with respect to each type of preparation.

7.1. Solo practice

The two most important areas of focus in sole preparation are:

• Mental math

As we mentioned briefly, the best use of your time is to focus on solving cases. You can start with cases listed on MBB sites since they are clearly stated and have worked solutions as well (e.g. Bain is a good place to start) and then move to more complex cases (our Case Library also offers a range of cases of different complexities). To build your confidence, start out on easier case questions, work through with the solutions, and don't worry about time. As you get better, you can move on to more difficult cases and try to get through them more quickly. You should practice around eight case studies on your own to build your confidence.

Another important area of practice is your mental mathematics as this skill will considerably increase your confidence and is neglected by many applicants - much to their immediate regret in the case interview. Find our mental math tool here or in our course, and practice at least ten minutes per day, from day one until the day before the interview.

7.2. Preparation with a partner

There are aspects of a case interview - such as asking clarifying questions - which you cannot do alone and this is why, after you feel comfortable, you should move on to practice with another person. There are two options here:

• Practicing with a peer
• Practicing with an ex-consultant

In theory they can be complementary - especially if you’re peer is also preparing for consulting interviews - and each have advantages and disadvantages. A peer is likely to practice with you for free for longer, however you may end up reinforcing some bad habits or unable to get actionable feedback. A consultant will be able to provide you the latter but having their help for the same number of hours as a peer will come at a higher cost. Let’s look at each option in more detail.

7.2.1. Peer preparation

Once you have worked through eight cases solo, you should be ready to simulate the case interview more closely and start working with another person.

Here, many candidates turn to peer practice - that is, doing mock case interviews with friends, classmates or others also applying to consulting. If you’re in university, and especially in business school, there will very likely be a consulting club for you to join and do lots of case practice with. If you don’t have anyone to practice, though, or if you just want to get a bit more volume in with others, our free meeting board lets you find fellow applicants from around the world with whom to practice. We recommend practicing around 10 to 15 ‘live’ cases to really get to a point where you feel comfortable.

7.2.2. Preparation with a consultant

You can do a lot practising by yourself and with peers. However, nothing will bring up your skills so quickly and profoundly as working with a real consultant.

Perhaps think about it like boxing. You can practice drills and work on punch bags all you want, but at some point you need to get into the ring and do some actual sparring if you ever want to be ready to fight.

Practicing with an ex consultant is essentialy a simulation of a case interview. Of course, it isn’t possible to secure the time of experienced top-tier consultants for free. However, when considering whether you should invest to boost your chances of success, it is worth considering the difference in your salary over even just a few years between getting into a top-tier firm versus a second-tier one. In the light of thousands in increased annual earnings (easily accumulating into millions over multiple years), it becomes clear that getting expert interview help really is one of the best investments you can make in your own future.

Should you decide to make this step, MyConsultingCoach can help, offering bespoke mentoring programmes , where you are paired with a 5+ year experienced, ex-MBB mentor of your choosing, who will then oversee your whole case interview preparation from start to finish - giving you your best possible chance of landing a job!

7.3. Practice for online interviews

Standard preparation for interview case studies will carry directly over to online cases.

However, if you want to do some more specific prep, you can work through cases solo to a timer and using a calculator and/or Excel (online cases generally allow calculators and second computers to help you, whilst these are banned in live case interviews).

Older PST-style questions also make great prep, but a particularly good simulation is the self-assessment tests included in our Case Academy course . These multiple choice business questions conducted with a strict time limit are great preparation for the current crop of online cases.

7.4. Fit interviews

As we’ve noted, even something billed as a case interview is very likely to contain a fit interview as a subset.

We have an article on fit interviews and also include a full set of lessons on how to answer fit questions properly as a subset of our comprehensive Case Academy course .

Here though, the important thing to convey is that you take preparing for fit questions every bit as seriously as you do case prep.

Since they sound the same as you might encounter when interviewing for other industries, the temptation is to regard these as “just normal interview questions”.

However, consulting firms take your answers to these questions a good deal more seriously than elsewhere.

This isn’t just for fluffy “corporate culture” reasons. The long hours and close teamwork, as well as the client-facing nature of management consulting, mean that your personality and ability to get on with others is going to be a big part of making you a tolerable and effective co-worker.

If you know you’ll have to spend 14+ hour working days with someone you hire and that your annual bonus depends on them not alienating clients, you better believe you’ll pay attention to their character in interview.

There are also hard-nosed financial reasons for the likes of McKinsey, Bain and BCG to drill down so hard on your answers.

In particular, top consultancies have huge issues with staff retention. The average management consultant only stays with these firms for around two years before they have moved on to a new industry.

In some cases, consultants bail out because they can’t keep up with the arduous consulting lifestyle of long hours and endless travel. In many instances, though, departing consultants are lured away by exit opportunities - such as the well trodden paths towards internal strategy roles, private equity or becoming a start-up founder.

Indeed, many individuals will intentionally use a two year stint in consulting as something like an MBA they are getting paid for - giving them accelerated exposure to the business world and letting them pivot into something new.

Consulting firms want to get a decent return on investment for training new recruits. Thus, they want hires who not only intend to stick with consulting longer-term, but also have a temperament that makes this feasible and an overall career trajectory where it just makes sense for them to stay put.

This should hammer home the point that, if you want to get an offer, you need to be fully prepared to answer fit questions - and to do so excellently - any time you have a case interview.

8. Interview day - what to expect, with tips

Of course, all this theory is well and good, but a lot of readers might be concerned about what exactly to expect in real life . It’s perfectly reasonable to want to get as clear a picture as possible here - we all want to know what we are going up against when we face a new challenge!

Indeed, it is important to think about your interview in more holistic terms, rather than just focusing on small aspects of analysis. Getting everything exactly correct is less important than the overall approach you take to reasoning and how you communicate - and candidates often lose sight of this fact.

In this section, then, we’ll run through the case interview experience from start to finish, directing you to resources with more details where appropriate. As a supplement to this, the following video from Bain is excellent. It portrays an abridged version of a case interview, but is very useful as a guide to what to expect - not just from Bain, but from McKinsey, BCG and any other high-level consulting firm.

8.1. Getting started

Though you might be shown through to the office by a staff member, usually your interviewer will come and collect you from a waiting area. Either way, when you first encounter them, you should greet your interviewer with a warm smile and a handshake (unless they do not offer their hand). Be confident without verging into arrogance. You will be asked to take a seat in the interviewer’s office, where the case interview can then begin.

8.1.1. First impressions

In reality, your assessment begins before you even sit down at your interviewer’s desk. Whether at a conscious level or not, the impression you make within the first few seconds of meeting your interviewer is likely to significantly inform the final hiring decision (again, whether consciously or not).

Your presentation and how you hold yourself and behave are all important . If this seems strange, consider that, if hired, you will be personally responsible for many clients’ impressions of the firm. These things are part of the job! Much of material on the fit interview is useful here, whilst we also cover first impressions and presentation generally in our article on what to wear to interview .

As we have noted above, your interview might start with a fit segment - that is, with the interviewer asking questions about your experiences, your soft skills, and motivation to want to join consulting generally and that firm in particular. In short, the kinds of things a case study can’t tell them about you. We have a fit interview article and course to get you up to speed here.

8.1.2. Down to business

Following an initial conversation, your interviewer will introduce your case study , providing a prompt for the question you have to answer. You will have a pen and paper in front of you and should (neatly) note down the salient pieces of information (keep this up throughout the interview).

It is crucial here that you don’t delve into analysis or calculations straight away . Case prompts can be tricky and easy to misunderstand, especially when you are under pressure. Rather, ask any questions you need to fully understand the case question and then validate that understanding with the interviewer before you kick off any analysis. Better to eliminate mistakes now than experience that sinking feeling of realising you have gotten the whole thing wrong halfway through your case!

This process is covered in our article on identifying the problem and in greater detail in our Case Academy lesson on that subject.

8.1.3. Analysis

Once you understand the problem, you should take a few seconds to set your thoughts in order and draw up an initial structure for how you want to proceed. You might benefit from utilising one or more of our building blocks here to make a strong start. Present this to your interviewer and get their approval before you get into the nuts and bolts of analysis.

We cover the mechanics of how to structure your problem and lead the analysis in our articles here and here and more thoroughly in the MCC Case Academy . What it is important to convey here, though, is that your case interview is supposed to be a conversation rather than a written exam . Your interviewer takes a role closer to a co-worker than an invigilator and you should be conversing with them throughout.

Indeed, how you communicate with your interviewer and explain your rationale is a crucial element of how you will be assessed. Case questions in general, are not posed to see if you can produce the correct answer, but rather to see how you think . Your interviewer wants to see you approach the case in a structured, rational fashion. The only way they are going to know your thought processes, though, is if you tell them!

To demonstrate this point, here is another excellent video from Bain, where candidates are compared.

Note that multiple different answers to each question are considered acceptable and that Bain is primarily concerned with the thought processes of the candidate’s exhibit .

Another reason why communication is absolutely essential to case interview success is the simple reason that you will not have all the facts you need to complete your analysis at the outset. Rather, you will usually have to ask the interviewer for additional data throughout the case to allow you to proceed .

NB: Don't be let down by your math!

Your ability to quickly and accurately interpret these charts and other figures under pressure is one of the skills that is being assessed. You will also need to make any calculations with the same speed and accuracy (without a calculator!). As such, be sure that you are up to speed on your consulting math .

8.1.4. Recommendation

Finally, you will be asked to present a recommendation. This should be delivered in a brief, top-down "elevator pitch" format , as if you are speaking to a time-pressured CEO. Again here, how you communicate will be just as important as the details of what you say, and you should aim to speak clearly and with confidence.

For more detail on how to give the perfect recommendation, take a look at our articles on the Pyramid Principle and providing recommendations , as well the relevant lesson within MCC Academy .

8.1.5. Wrapping up

After your case is complete, there might be a few more fit questions - including a chance for you to ask some questions of the interviewer . This is your opportunity to make a good parting impression.

We deal with the details in our fit interview resources. However, it is always worth bearing in mind just how many candidates your interviewers are going to see giving similar answers to the same questions in the same office. A pretty obvious pre-requisite to being considered for a job is that your interviewer remembers you in the first place. Whilst you shouldn't do something stupid just to be noticed, asking interesting parting questions is a good way to be remembered.

Now, with the interview wrapped up, it’s time to shake hands, thank the interviewer for their time and leave the room .

You might have other case interviews or tests that day or you might be heading home. Either way, if know that you did all you could to prepare, you can leave content in the knowledge that you have the best possible chance of receiving an email with a job offer. This is our mission at MCC - to provide all the resources you need to realise your full potential and land your dream consulting job!

8.2. Remote and one-way interview tips

Zoom case interviews and “one-way” automated fit interviews are becoming more common as selection processes are increasingly remote, with these new formats being accompanied by their own unique challenges.

Obviously you won’t have to worry about lobbies and shaking hands for a video interview. However, a lot remains the same. You still need to do the same prep in terms of getting good at case cracking and expressing your fit answers. The specific considerations around remote case interviews are, in effect, around making sure you come across as effectively as you would in person.

8.2.1. Connection

It sounds trivial, but a successful video case interview of any kind presupposes a functioning computer with a stable and sufficient internet connection.

Absolutely don’t forget to have your laptop plugged in, as your battery will definitely let you down mid-interview. Similarly, make sure any housemates or family know not to use the microwave, vacuum cleaner or anything else that makes wifi cut out (or makes a lot of noise, obviously)

If you have to connect on a platform you don’t use much (for example, if it’s on Teams and you’re used to Zoom), make sure you have the up to date version of the app in advance, rather than having to wait for an obligatory download and end up late to join. Whilst you’re at it, make sure you’re familiar with the controls etc. At the risk of being made fun of, don’t be afraid to have a practice call with a friend.

8.2.2. Dress

You might get guidance on a slightly more relaxed dress code for a Zoom interview. However, if in doubt, dress as you would for the real thing (see our article here ).

Either way, always remember that presentation is part of what you are being assessed on - the firm needs to know you can be presentable for clients. Taking this stuff seriously also shows respect for your interviewer and their time in interviewing you.

8.2.3. Lighting

An aspect of presentation that you have to devote some thought to for a Zoom case interview is your lighting.

Hopefully, you long ago nailed a lighting set-up during the Covid lockdowns. However, make sure to check your lighting in advance with your webcam - bearing in mind what time if day your case interview actually is. If your case interview is late afternoon, don’t just check in the morning. Make sure you aren’t going to be blinded from light coming in a window behind your screen, or that you end up with the weird shadow stripes from blinds all over your face.

Natural light is always best, but if there won’t be much of that during your interview, you’ll likely want to experiment with moving some lamps around.

8.2.4. Clarity

The actual stories you tell in an automated “one-way” fit interview will be the same as for a live equivalent. If anything, things should be easier, as you can rattle off a practised monologue without an interviewer interrupting you to ask for clarifications.

You can probably also assume that the algorithm assessing your performance is sufficiently capable that it will be observing you at much the same level as a human interviewer. However, it is probably still worth speaking as clearly as possible with these kinds of interviews and paying extra attention to your lighting to ensure that your face is clearly visible.

No doubt the AIs scoring these interviews are improving all the time, but you still want to make their job as easy as possible. Just think about the same things as you would with a live Zoom case interview, but more so.

9. How we can help

There are lots of great free resources on this site to get you started with preparation, from all our articles on case solving and consulting skills to our free case library and peer practice meeting board .

To step your preparation up a notch, though, our Case Academy course will give you everything you need to know to solve the most complex of cases - whether those are in live case interviews, with chatbots, written tests or any other format.

Whatever kind of case you end up facing, nothing will bring up your skillset faster than the kind of acute, actionable feedback you can get from a mock case interview a real, MBB consultant. Whilst it's possible to get by without this kind of coaching, it does tend to be the biggest single difference maker for successful candidates. From one to one practice to personalised preparation plan, our tailored coaching packages will help you achieve your objectives.

1. introduction to capital one ↑.

Capital One is unique. Despite being founded as a single-business bank in 1994, it has grown to become the 9th largest bank ($475.6bn in assets) in the United States as of this writing, behind firms such as JP Morgan Chase and Goldman Sachs . The business was initially focused solely on credit cards but now includes the following 3 verticals:

• Credit Cards
• Consumer Banking
• Commercial Banking

The company's success is driven largely by its clever use of data . It has developed and continues to develop sophisticated strategies and techniques for identifying and directly marketing to profitable customers. This gave the company a competitive advantage over traditional banks, which have historically focused on broad (rather than targeted) marketing.

With its unusual history and focus on technology, Capital One has more of a "tech firm" feel, which is different from what you'd expect from a giant financial institution. It also has its own strategy group , which serves as its internal consulting firm. 

If you’re reading this article, you’re most likely interested in applying for a role at Capital One that includes case interviews as part of its application process. Or perhaps you’re already preparing for a case interview with the firm. Either way, before we get into the application and interview process, let’s take a look at how much you stand to earn if you land a spot at Capital One.

1.1 Capital One roles and salaries

2. Capital One interview process ↑

Capital One hires for roles ranging from call centre reps to software engineers and business analysts. The nature of the interview process you can expect at Capital One depends on the role you’re applying for. Not every role will have a case interview.

Here are the roles that undergo case interviews at Capital One:

• Strategy analyst
• Operations analyst
• Data analyst
• Strategy consultant
• Strategy associate
• Product manager

The application process for these roles includes 5 main stages:

• Resume and cover letter submission
• Virtual Job Tryouts (online assessment tests)
• Recruiter screening
• Mini case interview
• Power Day (3-5 interviews)

The application process for the different roles is more or less the same: largely focused on case interviews. Some roles, like the strategy consultant and strategy associate roles, may include a written case interview, along with the standard ones during the Power Day. 

Before we dive more deeply into case interviews, let's take a closer look at each step of the Capital One interview process.

2.1 Resume & cover letter submission

First, recruiters will look at your resume and assess if your experience matches the position you’ve applied for. 

To help tailor your application to the position you’re targeting, use our free resume guide and free cover letter guide .

If you’re looking for expert feedback, you can also get input from our team of expert recruiters , who will cover what achievements to focus on (or ignore), how to get more impact from your bullet points, and more.

2.2 Capital One Virtual Job Tryouts

Once you apply, you’ll get email instructions to join the Virtual Job Tryouts or VJT, Capital One’s version of an online assessment. The VJT consists of different tests and tasks, which vary depending on the role. Here are some examples of the modules you may encounter, based on Capital One’s Career FAQs :

• Manage Relationships: Make decisions and respond to scenarios you’ll commonly encounter in the role.
• Work Your Business Case: Review and integrate information from multiple sources about a fictitious business and offer solutions to help it succeed.
• Tell Us Your Story: Talk about your work experiences and background that have helped shape who you are.
• Describe Your Approach: Talk about your preferred style and approach to work.
• Quantitative Assessment (for business analyst candidates) : Take a standard quantitative test where you’ll be given a data set and 7 to 11 questions to answer. You'll need to use a spreadsheet to solve mathematical and analytical problems.

Below we’ve gathered a few quantitative assessment questions from the VJT as reported on Glassdoor .

Example Capital One VJT Quantitative Assessment questions

• Ali and Sophie are budding musicians who have been playing Thursday night shows at a local live music venue. The venue told them that over the course of the last four weeks, they’ve had 900 tickets sold for their shows. They are curious to see how many people are repeat fans, coming to more than one show. The venue’s recent customer survey says that 60% of fans have come once, 30% have come twice, 6% have come three times, and 4% have come four times. How many unique people have seen an Ali and Sophie show during this period?
• You make a change to your business model and add another employee. Calculate how many weeks it would take for the investment you've made (labour hours, infrastructure changes, training hours, reduced production in the first few weeks, etc.) to pay off and make a profit.
• Two bikers leave from 2 different locations and try to reach a destination. Calculate to determine which biker will reach the location first and in how many hours. These are not static variables, as the speed of each biker changes throughout the journey.

On average, the VJT online assessment tests take 20 to 45 minutes to complete.

2.3 Recruiter screening

If you pass the VJT, a recruiter will contact you to ask you further questions and to speak more about the company and the role. You can expect ‘getting to know’ questions such as:

• Why Capital One?
• Walk me through your resume.
• ​​Tell me something about yourself that’s not on your resume.
• What’s your biggest accomplishment?
• How did you hear about this position?
• What are your strengths and weaknesses?

This list of 23 common interview questions by Capital One is a good resource to review with example questions you can use when you practise.

2.4 Mini case interview

During your recruiter call, your recruiter will also tell you about your next steps, the first of which will be a mini case interview. This will be conducted via phone or video call. Be ready to hit the ground running in this interview. Don't expect much "getting to know you" discussion because they usually get straight to the case. This interview will normally last 30 minutes to an hour. 

Not much information about the mini case interview is available online via Capital One’s website, so we only have candidate reports to go by.

According to several PM candidate reports, the PM mini case will likely be about any one of Capital One’s products: the Capital One Shopping browser extension, the Capital One Venture Card, or the Capital One Mobile app. You could also receive other product questions.

As for the mini case for analyst roles, many candidates report getting a quant-heavy case that lasts for about 45 minutes. Your recruiter will give you information about it beforehand, including a sample case which is likely to be very similar to the actual mini case you’ll be given.

2.5 Power Day

Once you pass all the initial steps, you’ll get an invitation to your Power Day or Super Day. This is the final round which consists of 3-5 back-to-back interviews. 

Capital One has fully transitioned to virtual interviews, so you can expect your Power Day interviews to be conducted online. Each interview may last for up to 1 hour. You’ll have a 1-hour break somewhere in between.

Here’s a quick look at what a Power Day looks based on the role:

• Business analyst: 2 case interviews and 1 product interview, behavioural questions at the start of each interview
• Data analyst : 2 case interviews, behavioural interview, coding or data challenge interview
• Strategy associate and strategy analyst: 1 written case interview, 2 standard case interviews, behavioural interview

Now you know the interview process, let's go deeper into the interview questions you can expect to face.

3. Capital One interview questions ↑

In this section, we'll take a look at the type of questions you can expect to face in your Capital One interview. We'll start with the most important, and the most challenging: case interview questions.

3.1 Capital One case interviews

Case interviews are the most important part of the Capital One interview process. The company uses the interviewer-led approach, which is similar to the method used by McKinsey in its case interviews. 

Capital One case interviews are not limited to cases in the financial or banking industry. That’s because what the company wants to test is how you think, versus what you know about Capital One or finance.

3.1.1 Capital One case interview sections

While the industry or business used in Capital One case interviews may vary, its case interviews will always include 3 sections:

• Introduction of the business situation and framework
• Calculations based on key concepts and drivers of the case
• Your recommendation and business decision

We've embedded below a short introductory video by Capital One for your reference. 

Each section of the case interview has particular things you'll need to prepare for. Let's look at each section, breaking down the mock interview in the Capital One video as our example:

A. Introduction of the business situation and framework

The first several minutes of the interview will cover the business scenario and case framework. During this part, your interviewer will introduce the hypothetical business scenario, laying out the different aspects of the situation. 

After introducing the scenario briefly, your interviewer will then ask you a broad question. In the mock interview video, the question is: “Your first task is to increase the profitability of the Giant Bus route from New York City to DC. What factors would you consider to determine profitability?”

For this stage of the interview, you have two objectives:

• Ask clarifying questions to make sure that you understand the situation correctly. Many candidates skip this step, but it's essential because it will help you put together a more relevant framework.
• Put together a simple case framework to answer the interviewer's question. The objective of this framework is to identify and communicate key areas that you will consider to answer the interviewer's main question.

As we’ve mentioned above, Capital One’s case interviews are interviewer-led. You can expect your interviewer to lead the course of the interview with questions along the way. That said, we still recommend that you try and drive the case forward yourself to a certain extent, by communicating the implications of your answer with the interviewer. This will show that you're able to think a few steps ahead and take an active approach to problem-solving.

B. Calculations based on key concepts and drivers of the case

The second stage of the interview is heavily focused on maths skills . The recruiter will provide you with some data, and ask you to perform calculations.

In the mock interview video, the interviewer shows a report of the peak travel time for the bus company, a comparison of three travel methods for the route, and the bus company’s capacity utilisation. While showing the reports, the interviewer asks the candidate to analyse the figures and give their take on the current situation.

At this point, to back up your answer, you’ll need to make a few quick calculations. It's important to ask questions at this stage, as the recruiter may have additional data that they have not yet provided.

Make sure you talk through your logic to show the interviewer your problem-solving skills. This will also help them steer you back on track if you've misread any of the data.

Compared with the case interviews used at consulting firms, the case interviews at Capital One tend to have a greater focus on quantitative questions. So you should expect to spend more time on these types of quant problems during your interview, and less time on other areas, like creative brainstorming.

C. Your recommendation and business decision

In the final stage of the interview, you'll be expected to make a recommendation and defend it. To form your recommendation, draw on the calculations from the previous stage. Consider the numbers, use your intuition, and make a decision. 

For example, the candidate in the mock interview’s final recommendation is to move to a 15-minute frequency for the buses during peak hours, mentioning the risk involved in the recommendation. 

The specific strategy you suggest is less important than your logic and ability to defend it. During this part, expect the recruiter to question your approach. They may ask you how you would go about identifying other opportunities. You could also take the initiative, like the candidate in the mock interview example, to provide additional ideas to explore to achieve profitability.

3.1.2 Capital One case interview example: Ice Cream Corporation

Here’s a breakdown of another mock case interview by Capital One. It’s a little longer than the latest intro video, but it has a lot of helpful information and shows different interview scenarios. For your reference, we’ve summarised the key takeaways per section.

The interviewer opens the case by introducing the scenario: “You’re the CEO of an Ice Cream Corporation. What are the key factors you would consider when developing a strategy to grow profits for the Ice Cream Corporation?”

In the video, the first candidate asks several clarifying questions about the role of the CEO regarding product and sales. These questions help narrow down the scope of the interview.

After asking these questions and making notes along the way, the first candidate answers the main question regarding the key factors. After discussing these further with the interviewer, the candidate comes up with “pricing” as the key factor, and the key concepts to keep in mind: “role of promotional pricing, temporary to avoid a price war, and risk of the stocking-up effect”.

The video shows other examples of key factors that other candidates might bring up. This shows that there is no right or wrong way to get to an answer. It also shows an instance where the interviewer redirects the candidate’s answer, to show that it’s common for a Capital One interviewer to provide cues and hints to lead you to a specific topic so that you can do a deeper dive into it.

What follows is the quantitative section of the interview where the interviewer will present some data and ask you to perform some calculations. As we’ve mentioned above, these calculations form the basis for your final recommendation.

In the sample case, the candidate is asked to calculate the total monthly profit for Ice Cream Corporation, given the following data:

Price per carton = $5

Cost per carton = $1

Demand = 100 cartons/month

As you will see in the video, the first candidate asks how much of the cost is variable versus fixed. Don’t reserve your clarifying questions for the introduction; ask clarifying questions wherever you feel they’re necessary. 

Variable cost per carton = $1

Fixed cost per carton = $0

At this point, the calculation is straightforward.

($5-$1) X 100 cartons = $400 profit

Talk through your calculations as the candidates do in the mock interview. This doesn’t just highlight your maths skills but also your problem-solving skills.

Most calculations at Capital One case interviews tend to be simple. But based on this mock interview sample, you’ll see that you might encounter calculations that vary in terms of complexity, like elasticity of demand and break-even calculations. These require a little extra work, but your approach should be the same:

• Understand the data provided
• Ask for more information when necessary
• Lay out your approach
• Perform the calculations

If you’re not familiar with a concept, don’t be afraid to ask for further clarification.

The mock interview examples show different recommendation approaches. You can go conservative or bullish. There’s no right or wrong answer, as long as you can defend your recommendation, as the candidates in the mock interview video do. 

Another thing that interviewers do in the mock interview is challenge the candidates further by questioning their approach or asking them how they might address their own apprehensions about the strategy.

3.1.3 Additional tips for your Capital One case interview ↑

Here are a few more helpful tips to keep in mind during your case interview at Capital One. 

#Expect to be given a case from outside the finance industry

As we mentioned above, Capital One likes to use cases from different industries. It’s because what they want to test you on is how you think and not how much you know about the finance industry or Capital One as a company. It’s also a preview of the scope of work you might do at Capital One if you do land a job there. 

#Brush up on your maths and bring a calculator

Capital One case interviews are known for being more quantitative-focused compared to other companies. For this reason, you’ll want to brush up on your maths. 

Here are some common calculations that might occur during your Capital One case interview:

• Weighted average
• Expected value
• Contribution margin

Capital One allows you to bring a calculator during your case interview, so be sure to bring one that’s easy to use.

#Take notes 

As the interviewer describes the case, be sure to take notes so you have all the information you need as you answer each question and make your final recommendation.

#Pause before you speak

Don’t be afraid to ask for a moment to gather your thoughts whenever you need to. Give yourself a minute to look back at your notes to make sure you understand everything before speaking out.

#Listen carefully and ask clarifying questions

Your first task during the case interview is to make sure you understand the situation correctly by asking the right clarification questions.

This is what analysts at Capital One and other consulting firms do with clients. They sit down with them, listen carefully to the problem they have, and ask clarification questions before trying to solve the problem. They do this because it's impossible to solve a business problem you don't understand in detail. Therefore, you should follow a similar approach in your cases.

Additionally, if there are any concepts brought up that you don’t understand, don’t be afraid to ask for clarification. It’s also good practice to repeat the explanation in your own words so you interviewer can validate your understanding.

#Talk through your thought process, show your work as you do it

What Capital One wants to see in your case interview is your approach to solving business problems. They want to see how you think, so you’ll need to show them. Talk through your decision-making process and calculations and state any assumptions you’re making. Show them your notes while you’re at it. Capital One conducts virtual interviews, so you may want to use the Whiteboard function or Screenshare function over Zoom. 

#Listen for hints and cues

Capital One’s case interviews are interviewer-led, so your interviewer will often steer the conversation to a specific topic or focus if they deem it necessary. Listen carefully for such hints and cues. This might sound obvious but candidates sometimes get so stressed that they don't pick up on the hints interviewers give them.

#Avoid talking about your resume or qualifications

You only have an hour to showcase your skills during your case interview, so focus on the case itself instead of trying to insert your credentials. You’ll have a chance to do this in the behavioural parts of your Power Day interviews.

3.2 Capital One behavioural and fit i nterview questions ↑

In addition to case interviews, Capital One also uses behavioural questions/interviews, as most companies do. If you’re applying for a business analyst role, you may not get a whole interview devoted specifically to behavioural questions. Instead, you can expect to face them at the start of your case and product interviews.

Behavioural interview questions asked at Capital One fall into two main categories:

• Fit questions. These are generic questions such as “Why financial services?” or “Why Capital One?”
• Personal Experience Interview (PEI) questions. These are questions such as “Tell me about a time when you led a team through a difficult situation” Or “Tell me about a time when you had to manage a team conflict.”

We've written extensively about fit / PEI questions in other guides. But in summary here are the top 5 fit and PEI questions you should prepare for at Capital One or other firms.

Example Capital One behavioural questions: fit

• Why financial services?
• Tell me something about yourself that’s not on your resume.
• Tell me about your greatest accomplishment.

Example Capital One behavioural questions: PEI (Tell me about a time when…)

• You failed at work .
• You worked in a team and had to manage a conflict .
• You had a disagreement with a colleague / boss .
• You had to change someone's / a group's mind
• You led a team through a difficult situation .

Capital One is known to favour the STAR method when it comes to answering behavioural questions. So, for your interview, plan to answer behavioural questions using the following format:

S - Situation

This approach will help you to answer each question in a clear, and methodical way, which are great qualities to demonstrate when interviewing with Capital One.

3.2.1 "Why Capital One?" interview question ↑

You're almost guaranteed to be asked this question, so let's dive a bit deeper into how you should answer it. Here are 3 ways to make your answer stand out:

Name-drop: Before the interview, make an effort to meet with or call one or more current employees of the firm. Ask them what it’s like working there, why they chose Capital One and what’s unique about it. This will give you specific talking points for your answer, and mentioning their names shows the interviewer that you’ve put in effort to get to know the company.

Be specific. Test out your answer by swapping another bank’s name with the one you’ve got in mind. If your answer could also apply to this other bank, then you need to fine-tune it.

Keep up with recent activity: Being aware of the latest deals and developments in the department you’re applying to will give you an idea of what kind of projects you’ll get to work on, and whether they sound interesting to you. Bringing them up in the interview will show the interviewer that you’ve done your research and stay up to date on market news.

Example answer: "Why do you want to work at Capital One?"

“I want to work at Capital One for three main reasons. First, I want to work in a very data-driven environment and to have access to a vast amount of data when working strategically. I've been really impressed with Capital One's pioneering use of data and machine learning in the banking sector, which has helped the company gain market share across its verticals.

Second, I've been impressed with Capital One's strategy regarding a banking-as-a-service model and embedded finance. I saw an interview with CEO Richard Fairbank talking about how all banks needed to collaborate with fintech apps to provide instantaneous results for customers, rather than working in silos, and I thought he articulated a really strong vision.

Finally, I’ve had a few conversations with Seth White and Tamara Grey, associates in the McLean office, and they gave me a great impression of the firm as a whole. Seth in particular encouraged me to apply to the Travel team, as we share a similar educational background, and he was complimentary of the opportunities he’s been given to succeed."

3.3 Product questions

If you're interviewing for a business analyst role, one of your Power Day interviews will be a product interview. Compared to the very quantitative case interviews, the product interview is a lot more qualitative, meaning you'll need to demonstrate creative thinking.

In almost all the interview reports we've seen, the candidate was asked to improve a product in some way. We recommend you read our article on how to answer product improvement questions to help you structure your response.

Example Capital One product questions from business analyst candidates:

• Describe 12 uses for an alarm clock
• How would you redesign an alarm clock?
• What is the customer base for this product?
• Describe 10 ways to improve an umbrella
• How would you improve this water bottle?
• What's your favorite product and how would you improve it?

4. Capital One case interview examples ↑

Now that you know how case interviews at Capital One work, it’s time to get some practice. One of the best ways to do so is to study case interview examples. There are many free examples online, and we’ve listed a few here for your reference:

• Magazine publishing case interview (by Capital One)
• Sandwich shop case interview (by Capital One)
• Case interview playbook (by Capital One)
• Independent coffee shop case interview (by Capital One)
• Phone card case interview (by TBS Education)

Check out our list of case interview examples from other top consulting firms . The companies listed here are consulting companies rather than banks, but it’s helpful to study them as Capital One uses examples from all sorts of industries

5 . How do I prepare for a Capital One case interview? ↑

Practising case interview examples is an important part of your preparation, but it’s not the only thing you can do. Here’s how we recommend structuring your Capital One case interview prep plan, with links to resources to help you round out your preparation:

5.1 Use Capital One real case study examples for research

Case interviews require no prior knowledge. However, you can bet that overall your interviews at Capital One will go a lot better if you go in having done some research on the company and the wider financial industry.

Capital One shares case studies on its website, such as this one on real estate treasury management, which are well worth looking over. You might also want to take a look at some of the articles on Capital One's insights center . This piece about Capital One’s pioneering work with data analytics and AI provides a good overview of the company’s tech-forward approach to banking.

If you're coming from a finance background, you may already have a good knowledge of Capital One's place in the sector. If not, check out Investopedia for a brief summary.

5.2 Become really confident with your maths skills

You don't have to have a perfect GPA or GMAT score to succeed at case interview maths. And in any case, during your Capital One interviews, you will be allowed to use a calculator. That said, it will help if you're confident performing mental maths quickly and accurately.

In order to do this, it’s essential to know the formulas for common metrics such as: 

it’s also useful to know a few shortcuts to help you solve problems more quickly. To learn more about these topics, check out our free guide to case interview maths .

In our experience, the most successful applicants start their interview preparation by practising maths skills, so make sure you prioritise this step.

5.3 Develop a consistent method to crack cases

One of the biggest challenges of interviewing with Capital One is solving cases that you’ve never seen before. Each case can be difficult, and you’ll have to perform well across multiple case interviews to get an offer.

That’s why it’s critical for you to have a consistent approach to solving cases. Capital One uses interviewer-led case interviews, which can be broken down into the following types of questions:

• Framework development
• Quant question – Data provided
• Creativity question
• Recommendation

If you can crack each type of question (within a case), then you can crack the overall case. 

Check out our suggested structured method for answering case interviews or come up with your own. Choose a method that you can consistently incorporate when practising solving case interviews.

5.4 Learn from every mistake you make

During case interview preparation, the quality of your preparation is just as important as the quantity of time that you dedicate. It's better to do 20 cases thoughtfully than to rush through 40 cases. 

We recommend keeping a notebook where you record improvement opportunities and specific things you did well for each case. 

The notebook and self-evaluation will help you become more strategic and efficient with your preparation. It's also a good idea to go back and redo old cases. For example, after you have done case #20, you could go back to case #1, to make sure you are not repeating the same mistakes.

The minimum preparation time required to succeed in case interviews is probably around 30 hours. However, if you don't prepare thoughtfully, it may take much longer. So take notes, be strategic, learn from your mistakes, and keep practising!

5.5 Practise with peers

Once you're in command of the subject matter, you'll want to start practising cases. But by yourself, you can’t simulate thinking on your feet or the pressure of performing in front of a stranger. Plus, there are no unexpected follow-up questions and no feedback. 

If you have friends or peers who can do mock interviews with you, that's an option worth trying. It’s free, but be warned, you may come up against the following problems:

• It’s hard to know if the feedback you get is accurate
• They’re unlikely to have insider knowledge of interviews at your target company
• On peer platforms, people often waste your time by not showing up

For those reasons, many candidates skip peer mock interviews and go straight to mock interviews with an expert. 

5.6 Practise with experienced case interviewers

In our experience, practising real interviews with experts who can give you company-specific feedback makes a huge difference.

Find a consulting interview coach so you can:

• Test yourself under real interview conditions
• Get accurate feedback from a real expert
• Build your confidence
• Get company-specific insights
• Learn how to tell the right stories, better.
• Save time by focusing your preparation

Landing a job at a top consulting company often results in a $50,000 per year or more increase in total compensation. In our experience, three or four coaching sessions worth ~$500 make a significant difference in your ability to land the job. That’s an ROI of 100x!
