interview in business research method

Interviews can be defined as a qualitative research technique which involves “conducting intensive individual interviews with a small number of respondents to explore their perspectives on a particular idea, program or situation.” [1]

There are three different formats of interviews: structured, semi-structured and unstructured.

Structured interviews consist of a series of pre-determined questions that all interviewees answer in the same order. Data analysis usually tends to be more straightforward because researcher can compare and contrast different answers given to the same questions.

Unstructured interviews are usually the least reliable from research viewpoint, because no questions are prepared prior to the interview and data collection is conducted in an informal manner. Unstructured interviews can be associated with a high level of bias and comparison of answers given by different respondents tends to be difficult due to the differences in formulation of questions.

Semi-structured interviews contain the components of both, structured and unstructured interviews. In semi-structured interviews, interviewer prepares a set of same questions to be answered by all interviewees. At the same time, additional questions might be asked during interviews to clarify and/or further expand certain issues.

Advantages of interviews include possibilities of collecting detailed information about research questions.  Moreover, in in this type of primary data collection researcher has direct control over the flow of process and she has a chance to clarify certain issues during the process if needed. Disadvantages, on the other hand, include longer time requirements and difficulties associated with arranging an appropriate time with perspective sample group members to conduct interviews.

When conducting interviews you should have an open mind and refrain from displaying disagreements in any forms when viewpoints expressed by interviewees contradict your own ideas. Moreover, timing and environment for interviews need to be scheduled effectively. Specifically, interviews need to be conducted in a relaxed environment, free of any forms of pressure for interviewees whatsoever.

Respected scholars warn that “in conducting an interview the interviewer should attempt to create a friendly, non-threatening atmosphere. Much as one does with a cover letter, the interviewer should give a brief, casual introduction to the study; stress the importance of the person’s participation; and assure anonymity, or at least confidentiality, when possible.” [2]

There is a risk of interviewee bias during the primary data collection process and this would seriously compromise the validity of the project findings. Some interviewer bias can be avoided by ensuring that the interviewer does not overreact to responses of the interviewee. Other steps that can be taken to help avoid or reduce interviewer bias include having the interviewer dress inconspicuously and appropriately for the environment and holding the interview in a private setting.  [3]

Research Interviews: An effective and insightful way of data collection

Research interviews play a pivotal role in collecting data for various academic, scientific, and professional endeavors. They provide researchers with an opportunity to delve deep into the thoughts, experiences, and perspectives of an individual, thus enabling a comprehensive understanding of complex phenomena. It is important for researchers to design an effective and insightful method of data collection on a particular topic. A research interview is typically a two-person meeting conducted to collect information on a certain topic. It is a qualitative data collection method to gain primary information.

The three key features of a research interview are as follows:

Table of Contents

The Significance of Research Interviews in Gathering Primary Data

The role of research interviews in gathering first-hand information is invaluable. Additionally, they allow researchers to interact directly with participants, enabling them to collect unfiltered primary data.

1. Subjective Experience

Research interviews facilitate in-depth exploration of a research topic. Thus, by engaging in one-to-one conversation with participants, researchers can delve into the nuances and complexities of their experiences, perspectives, and opinions. This allows comprehensive understanding of the research subject that may not be possible through other methods. Also, research interviews offer the unique advantage of capturing subjective experiences through personal narratives. Moreover, participants can express their thoughts, feelings, and beliefs, which add depth to the findings.

2. Personal Insights

Research interviews offer an opportunity for participants to share their views and opinions on the objective they are being interviewed for. Furthermore, participants can express their thoughts and experiences, providing rich qualitative data . Consequently, these personal narratives add a human element to the research, thus enhancing the understanding of the topic from the participants’ perspectives. Research interviews offer the opportunity to uncover unanticipated insights or emerging themes. Additionally, open-ended questions and active listening can help the researchers to identify new perspectives, ideas, or patterns that may not have been initially considered. As a result, these factors can lead to new avenues for exploration.

3. Clarification and Validation

Researchers can clarify participants’ responses and validate their understanding during an interview. This ensures accurate data collection and interpretation. Additionally, researchers can probe deeper into participants’ statements and seek clarification on any ambiguity in the information.

4. Contextual Information

Research interviews allow researchers to gather contextual information that offers a comprehensive understanding of the research topic. Additionally, participants can provide insights into the social, cultural, or environmental factors that shape their experiences, behaviors, and beliefs. This contextual information helps researchers place the data in a broader context and facilitates a more nuanced analysis.

5. Non-verbal Cues

In addition to verbal responses, research interviews allow researchers to observe non-verbal cues such as body language, facial expressions, and tone of voice. Additionally, non-verbal cues can convey information, such as emotions, attitudes, or levels of comfort. Furthermore, integrating non-verbal cues with verbal responses provides a more holistic understanding of participants’ experiences and enriches the data collection process.

Research interviews offer several advantages, making them a reliable tool for collecting information. However, choosing the right type of research interview is essential for collecting useful data.

Types of Research Interviews

There are several types of research interviews that researchers can use based on their research goals , the nature of their study, and the data they aim to collect. Here are some common types of research interviews:

1. Structured Interviews

• Structured interviews are standardized and follow a fixed format.
• Therefore, these interviews have a pre-determined set of questions.
• All the participants are asked the same set of questions in the same order.
• Therefore, this type of interview facilitates standardization and allows easy comparison and quantitative analysis of responses.
• As a result, structured interviews are used in surveys or studies which aims for a high level of standardization and comparability.

2. Semi-structured Interviews

• Semi-structured interviews offer a flexible framework by combining pre-determined questions.
• So, this gives an opportunity for follow-up questions and open-ended discussions.
• Researchers have a list of core questions but can adapt the interview depending on the participant’s responses.
• Consequently, this allows for in-depth exploration while maintaining some level of consistency across interviews.
• As a result, semi-structured interviews are widely used in qualitative research, where content-rich data is desired.

3. Unstructured Interviews

• Unstructured interviews provide the greatest flexibility and freedom in the interview process.
• This type do not have a pre-determined set of questions.
• Thus, the conversation flows naturally based on the participant’s responses and the researcher’s interests.
• Moreover, this type of interview allows for open-ended exploration and encourages participants to share their experiences, thoughts, and perspectives freely.
• Unstructured interviews useful to explore new or complex research topics, with limited preconceived questions.

4. Group Interviews (Focus Groups)

• Group interviews involve multiple participants who engage in a facilitated discussion on a specific topic.
• This format allows the interaction and exchange of ideas among participants, generating a group dynamic.
• Therefore, group interviews are beneficial for capturing diverse perspectives, and generating collective insights.
• They are often used in market research, social sciences, or studies demanding shared experiences.

5. Narrative Interviews

• Narrative interviews focus on eliciting participants’ personal stories, views, experiences, and narratives. Researchers aim to look into the individual’s life journey.
• As a result, this type of interview allows participants to construct and share their own narratives, providing rich qualitative data.
• Qualitative research, oral history, or studies focusing on individual experiences and identities uses narrative interviews.

6. Ethnographic Interviews

• Ethnographic interviews are conducted within the context of ethnographic research, where researchers immerse themselves in a specific social or cultural setting.
• These interviews aim to understand participants’ experiences, beliefs, and practices within their cultural context, thereby understanding diversity in different ethnic groups.
• Furthermore, ethnographic interviews involve building rapport, observing the participants’ daily lives, and engaging in conversations that capture the nuances of the culture under study.

It must be noted that these interview types are not mutually exclusive. Therefore, researchers often employ a combination of approaches to gather the most comprehensive data for their research. The choice of interview type depends on the research objectives and the nature of the research topic.

Steps of Conducting a Research Interview

Research interviews offer several benefits, and thus careful planning and execution of the entire process are important to gather in-depth information from the participants. While conducting an interview, it is essential to know the necessary steps to follow for ensuring success. The steps to conduct a research interview are as follows:

• Identify the objectives and understand the goals
• Select an appropriate interview format
• Organize the necessary materials for the interview
• Understand the questions to be addressed
• Analyze the demographics of interviewees
• Select the interviewees
• Design the interview questions to gather sufficient information
• Schedule the interview
• Explain the purpose of the interview
• Analyze the interviewee based on his/her responses

Considerations for Research Interviews

Since the flexible nature of research interviews makes them an invaluable tool for data collection, researchers must consider certain factors to make the process effective. They should avoid bias and preconceived notion against the participants. Furthermore, researchers must comply with ethical considerations and respect the cultural differences between them and the participants. Also, they should ensure careful tailoring of the questions to avoid making them offensive or derogatory. The interviewers must respect the privacy of the participants and ensure the confidentiality of their details.

By ensuring due diligence of these considerations associated with research interviews, researchers can maximize the validity and reliability of the collected data, leading to robust and meaningful research outcomes.

Types of Interviews in Research | Guide & Examples

Published on 4 May 2022 by Tegan George . Revised on 10 October 2022.

An interview is a qualitative research method that relies on asking questions in order to collect data . Interviews involve two or more people, one of whom is the interviewer asking the questions.

There are several types of interviews, often differentiated by their level of structure. Structured interviews have predetermined questions asked in a predetermined order. Unstructured interviews are more free-flowing, and semi-structured interviews fall in between.

Interviews are commonly used in market research, social science, and ethnographic research.

Table of contents

What is a structured interview, what is a semi-structured interview, what is an unstructured interview, what is a focus group, examples of interview questions, advantages and disadvantages of interviews, frequently asked questions about types of interviews.

Structured interviews have predetermined questions in a set order. They are often closed-ended, featuring dichotomous (yes/no) or multiple-choice questions. While open-ended structured interviews exist, they are much less common. The types of questions asked make structured interviews a predominantly quantitative tool.

Asking set questions in a set order can help you see patterns among responses, and it allows you to easily compare responses between participants while keeping other factors constant. This can mitigate biases and lead to higher reliability and validity. However, structured interviews can be overly formal, as well as limited in scope and flexibility.

• You feel very comfortable with your topic. This will help you formulate your questions most effectively.
• You have limited time or resources. Structured interviews are a bit more straightforward to analyse because of their closed-ended nature, and can be a doable undertaking for an individual.
• Your research question depends on holding environmental conditions between participants constant

Semi-structured interviews are a blend of structured and unstructured interviews. While the interviewer has a general plan for what they want to ask, the questions do not have to follow a particular phrasing or order.

Semi-structured interviews are often open-ended, allowing for flexibility, but follow a predetermined thematic framework, giving a sense of order. For this reason, they are often considered ‘the best of both worlds’.

However, if the questions differ substantially between participants, it can be challenging to look for patterns, lessening the generalisability and validity of your results.

• You have prior interview experience. It’s easier than you think to accidentally ask a leading question when coming up with questions on the fly. Overall, spontaneous questions are much more difficult than they may seem.
• Your research question is exploratory in nature. The answers you receive can help guide your future research.

An unstructured interview is the most flexible type of interview. The questions and the order in which they are asked are not set. Instead, the interview can proceed more spontaneously, based on the participant’s previous answers.

Unstructured interviews are by definition open-ended. This flexibility can help you gather detailed information on your topic, while still allowing you to observe patterns between participants.

However, so much flexibility means that they can be very challenging to conduct properly. You must be very careful not to ask leading questions, as biased responses can lead to lower reliability or even invalidate your research.

• You have a solid background in your research topic and have conducted interviews before
• Your research question is exploratory in nature, and you are seeking descriptive data that will deepen and contextualise your initial hypotheses
• Your research necessitates forming a deeper connection with your participants, encouraging them to feel comfortable revealing their true opinions and emotions

A focus group brings together a group of participants to answer questions on a topic of interest in a moderated setting. Focus groups are qualitative in nature and often study the group’s dynamic and body language in addition to their answers. Responses can guide future research on consumer products and services, human behaviour, or controversial topics.

Focus groups can provide more nuanced and unfiltered feedback than individual interviews and are easier to organise than experiments or large surveys. However, their small size leads to low external validity and the temptation as a researcher to ‘cherry-pick’ responses that fit your hypotheses.

• Your research focuses on the dynamics of group discussion or real-time responses to your topic
• Your questions are complex and rooted in feelings, opinions, and perceptions that cannot be answered with a ‘yes’ or ‘no’
• Your topic is exploratory in nature, and you are seeking information that will help you uncover new questions or future research ideas

Depending on the type of interview you are conducting, your questions will differ in style, phrasing, and intention. Structured interview questions are set and precise, while the other types of interviews allow for more open-endedness and flexibility.

Here are some examples.

• Semi-structured
• Unstructured
• Focus group
• Do you like dogs? Yes/No
• Do you associate dogs with feeling: happy; somewhat happy; neutral; somewhat unhappy; unhappy
• If yes, name one attribute of dogs that you like.
• If no, name one attribute of dogs that you don’t like.
• What feelings do dogs bring out in you?
• When you think more deeply about this, what experiences would you say your feelings are rooted in?

Interviews are a great research tool. They allow you to gather rich information and draw more detailed conclusions than other research methods, taking into consideration nonverbal cues, off-the-cuff reactions, and emotional responses.

However, they can also be time-consuming and deceptively challenging to conduct properly. Smaller sample sizes can cause their validity and reliability to suffer, and there is an inherent risk of interviewer effect arising from accidentally leading questions.

Here are some advantages and disadvantages of each type of interview that can help you decide if you’d like to utilise this research method.

The four most common types of interviews are:

• Structured interviews : The questions are predetermined in both topic and order.
• Semi-structured interviews : A few questions are predetermined, but other questions aren’t planned.
• Unstructured interviews : None of the questions are predetermined.
• Focus group interviews : The questions are presented to a group instead of one individual.

A structured interview is a data collection method that relies on asking questions in a set order to collect data on a topic. They are often quantitative in nature. Structured interviews are best used when:

• You already have a very clear understanding of your topic. Perhaps significant research has already been conducted, or you have done some prior research yourself, but you already possess a baseline for designing strong structured questions.
• You are constrained in terms of time or resources and need to analyse your data quickly and efficiently
• Your research question depends on strong parity between participants, with environmental conditions held constant

More flexible interview options include semi-structured interviews , unstructured interviews , and focus groups .

A semi-structured interview is a blend of structured and unstructured types of interviews. Semi-structured interviews are best used when:

• You have prior interview experience. Spontaneous questions are deceptively challenging, and it’s easy to accidentally ask a leading question or make a participant uncomfortable.
• Your research question is exploratory in nature. Participant answers can guide future research questions and help you develop a more robust knowledge base for future research.

An unstructured interview is the most flexible type of interview, but it is not always the best fit for your research topic.

Unstructured interviews are best used when:

• You are an experienced interviewer and have a very strong background in your research topic, since it is challenging to ask spontaneous, colloquial questions
• Your research question is exploratory in nature. While you may have developed hypotheses, you are open to discovering new or shifting viewpoints through the interview process.
• You are seeking descriptive data, and are ready to ask questions that will deepen and contextualise your initial thoughts and hypotheses
• Your research depends on forming connections with your participants and making them feel comfortable revealing deeper emotions, lived experiences, or thoughts

The interviewer effect is a type of bias that emerges when a characteristic of an interviewer (race, age, gender identity, etc.) influences the responses given by the interviewee.

There is a risk of an interviewer effect in all types of interviews , but it can be mitigated by writing really high-quality interview questions.

The Power of In-Depth Interviews in Market Research

In-depth interviews are an invaluable approach to conducting market research because they can act as a window into the underlying motivations, opinions, and behaviors of industry experts and professionals. Unlike focus groups, where interviewers are engaging with multiple interviewees at once, in-depth interviews are one-on-one conversations that allow for deep exploration into an individual's insights. Today, we’ll dive into when you should leverage in-depth interviews to fuel business success.

Maximizing Honesty and Authenticity

In-depth interviews present a unique opportunity to gain detailed insights from respondents by fostering a relaxed environment. The one-on-one setting encourages participants to open up, allowing them to share experiences, opinions, and motivations without the influence or pressure that can come with group dynamics. Sometimes, the topics being explored during research can be quite personal, so individual interviews may feel like a safer environment for respondents to share their thoughts openly. Without the need to conform to others' responses or shield their personal perspectives, respondents can feel free to express themselves fully and honestly, which leads to more authentic insights.

Tailoring the Conversation

When it comes to conducting market research, flexibility is important, especially as it relates to asking follow-ups and adjusting the line of questioning as you go. In-depth interviews are a highly flexible method in this regard. Since every respondent is different, the interviewer can adapt questions based on the flow of conversation and the unique responses of each individual. With other forms of research, such as surveys and focus groups, it is more difficult to make these kinds of adjustments. With surveys, the questions are pre-formatted, and with focus groups, time is limited due to the number of respondents, which causes interviewers to be more restricted.

Achieving Quality Over Quantity

In-depth interviews are particularly valuable when time and budget constraints limit the feasibility of large-scale research. By engaging in in-depth interviews with a smaller number of people, researchers can carefully select their respondents and gain rich insights from a reduced but arguably more impactful sample while maximizing their resources. This helps to ensure that companies obtain the insights they need to make meaningful business decisions.

Next time you conduct market research and find yourself needing authentic and tailored insights, consider conducting in-depth interviews with respondents that fit your exact criteria.
