structured interview is a systematic data collection technique where questions are asked in a predetermined order. It’s one of four main interview types used in research.

Typically, structured interviews are quantitative, though they can be qualitative if open-ended questions are used. This method is not limited to job interviews and the hiring process; it’s widely used in marketing, social sciences, survey research, and other fields.

This approach balances standardization with the ability to gather detailed information, making it a versatile tool to reduce bias in various research contexts.

What is a Structured Interview?

A structured interview is a systematic method of gathering information from respondents using a predetermined set of questions asked in a specific order. This format is designed to maintain consistency across all interviews for a particular study or purpose.

Key features of structured interviews include:

  • Standardized questions: All interviewees are asked the same questions in order.
  • Fixed response options: Often include closed-ended questions with predetermined answer choices.
  • Consistent delivery: Interviewers are trained to ask questions in the same manner for all respondents.
  • Limited flexibility: There’s little room for deviation from the script or follow-up questions.
  • Quantifiable data: Responses are easily coded and analyzed statistically.
  • Time-efficient: Generally quicker to conduct and analyze compared to other interview types.
  • Reduced interviewer bias: The structured format minimizes the interviewer’s influence on responses.

Structured interviews are particularly useful when comparing responses across many participants or when quantitative data analysis is required. However, they may lack the depth and flexibility of other interview formats, potentially missing nuanced information or unexpected insights.

When to Use a Structured Interview

Structured interviews are particularly beneficial when:

  • Hiring for multiple positions with the same requirements
  • Comparing candidates objectively for a role
  • Ensuring fair and consistent evaluation of all applicants
  • Gathering targeted information to assess key competencies

The structured format provides a clear framework that allows interviewers to effectively gather specific, job-relevant information to assess a candidate’s qualifications. By asking predetermined questions in the same order, the process becomes more standardized and objective.

This approach is useful when the hiring team understands the role and the necessary competencies. With a solid baseline of knowledge, they can develop targeted, structured interview questions that will elicit the most relevant responses from candidates.

Additionally, structured interviews can be advantageous when time or resources are limited. The systematic format streamlines the interview process and facilitates more efficient data analysis, enabling quicker decision-making. This is particularly helpful when environmental factors need to be held constant across all applicants.

Differences between different types of interviews

Interviews are a widely used qualitative research method that allows researchers to gather in-depth information from participants. They are versatile tools that can be adapted to various research needs and contexts. The types of interviews differ in structure, flexibility, and the nature of the data they typically collect.

Advantages and Disadvantages of Structured Interviews

Here are the main advantages and disadvantages of structured interviews:

AdvantagesDisadvantages
Consistency across interviewsLimited flexibility to explore new topics
Efficient to conduct and analyzeMay miss depth in responses
Easy quantification of dataCan feel impersonal or rigid
Reduced interviewer biasMay not capture unexpected insights
High replicabilityPotential for response bias due to fixed options
Suitable for large sample sizesLess effective for complex or sensitive topics
Clear and straightforward for intervieweesMay not adapt well to individual experiences
Simple to train interviewersCan be less engaging for participants
Good time managementMay oversimplify complex issues
Enhanced comparability across studiesLimited ability to clarify misunderstandings

Structured Interview Questions

Structured interview questions are carefully designed to gather specific information consistently across all respondents. These questions are typically:

  • Predetermined: Prepared in advance and asked all interviewees in the same order.
  • Standardized: Worded identically for each participant to ensure uniformity.
  • Often closed-ended: Many structured interview questions have limited response options.

Types of Structured Interview Questions

Here are some common types of structured interview questions:

  • Closed-ended questions:
    • Yes/No questions
    • Multiple choice questions
    • Likert scale questions (e.g., rate on a scale of 1-5)
  • Short answer questions: Require brief, specific responses.
  • Ranking questions: Ask respondents to order items or options.
  • Rating questions: Request evaluation on a numeric or descriptive scale.
  • Quantitative questions: Seek numerical data or frequencies.

Examples of Structured Interview Questions

  1. On a scale of 1 to 5, how satisfied are you with our customer service?
  2. How often do you use our product? (Daily/Weekly/Monthly/Rarely/Never)
  3. Have you experienced any technical issues with the software? (Yes/No)
  4. Which of the following features do you find most useful? (List options)
  5. How many times have you contacted customer support in the past month?

While structured interviews can include open-ended questions, these are typically limited and designed to elicit concise responses. The key is that all questions are asked similarly to all participants, ensuring consistency and comparability of responses across the entire sample.

How to Conduct a Structured Interview

Structured interviews are widely used in various fields, including market research, social sciences, and human resources. Here’s how to conduct structured interviews effectively:

Step 1: Set your goals and objectives

Begin by clearly defining what you aim to achieve with the interviews. Identify the specific information you need to gather and how it aligns with your research or organizational goals. This step is crucial as it guides the entire interview process and ensures your questions are purposeful and relevant.

Step 2: Design your questions

Develop a set of questions that directly address your goals. In structured interviews, these questions should be:

  • Clear and unambiguous
  • Focused on one topic per question
  • Ordered logically
  • Primarily closed-ended for ease of analysis

Ensure the questions are neutral and avoid leading the respondent to particular answers.

Step 3: Assemble your participants

Identify and recruit participants who match your target demographic or criteria. Consider factors such as sample size, diversity, and representation to ensure your results are meaningful and applicable to your research objectives.

Step 4: Decide on your medium

Choose how you’ll conduct the interviews. Options include:

  • In-person interviews
  • Phone interviews
  • Video calls
  • Written questionnaires

Your choice should consider factors like geographical limitations, resource availability, and the nature of your questions.

Step 5: Conduct your interviews

When conducting the interviews:

  • Follow the predetermined script exactly
  • Ask questions in the same order for all participants
  • Maintain a neutral tone and avoid influencing responses
  • Record answers accurately and consistently
  • Adhere to ethical guidelines, including obtaining informed consent and ensuring confidentiality

How to Analyze Structured Interview Results

  1. Review and score responses: Assess each candidate’s answers against established scoring criteria or rubrics. This provides quantifiable data.
  2. Compare across candidates: Look for patterns, strengths, and weaknesses across all applicant responses to identify the best fit.
  3. Integrate with other assessments: Combine structured interview results with other hiring data, such as resumes, skills tests, and reference checks.

Presenting Your Results

When communicating structured interview findings, be prepared to:

  • Summarize key insights and overall candidate rankings
  • Provide specific examples that demonstrate how candidates performed
  • Explain how the structured process ensured fair and objective evaluation
  • Make a clear, data-driven recommendation for the top candidate(s)

Interview Methodology

To better understand the experiences and perspectives of small business owners during the COVID-19 pandemic, we conducted a series of in-depth, semi-structured interviews. This qualitative approach allowed us to gather rich, contextual data about the unique challenges faced by entrepreneurs during this unprecedented time.

Participant Selection 

We utilized purposive sampling to identify small business owners who met the following criteria:

  • Operated a for-profit small business (fewer than 50 employees)
  • Located within the tri-state area
  • In business for a minimum of 3 years before the pandemic

We recruited 18 small business owners to participate in the study using a combination of outreach through local business associations and referrals from previous participants.

Interview Protocol 

Each interview followed a standardized protocol consisting of open-ended questions covering the following topics:

  1. Overview of the business – industry, years in operation, number of employees
  2. Impact of the COVID-19 pandemic on business operations and revenue
  3. Strategies employed to adapt and respond to pandemic-related challenges
  4. Access to and utilization of government assistance programs
  5. Outlook on the future of the business post-pandemic

Interviews were conducted in person or via video conference, based on participant preference, and lasted 45-90 minutes. All sessions were audio recorded with the participant’s consent.

Data Analysis 

Audio recordings were professionally transcribed and then analyzed using a thematic analysis approach. The research team reviewed the transcripts multiple times to identify recurring themes, patterns, and insights. A coding framework was developed collaboratively, and transcripts were coded accordingly using qualitative data analysis software. To ensure the trustworthiness of the findings, we employed several validation techniques, including respondent validation, investigator triangulation, and an audit trail. This allowed us to thoroughly explore the nuanced experiences of small business owners during the COVID-19 crisis.
