Structured interview: Why they work and how to conduct one?

Structured interviews have become a cornerstone in modern recruitment processes, offering significant advantages over traditional, unstructured approaches.

A study by Harvard Business Review found that structured interviews can increase the validity of candidate selection decisions by up to 24% compared to unstructured interviews, highlighting their effectiveness in predicting job performance.

This blog explores what structured interviews entail, why they are effective, and provides guidance on conducting them effectively in recruitment settings.

What is a structured interview?

A structured interview is a standardized method of interviewing candidates where each interviewee is asked the same set of predetermined questions in the same order. This approach contrasts with unstructured interviews, where questions may vary based on the flow of the conversation or the interviewer’s intuition.

Key features

1. Standardized questions: All candidates are asked the same questions, ensuring consistency and fairness.
2. Scoring system: Responses are evaluated using a predetermined scoring system, which helps in objectively comparing candidates.
3. Predictive validity: Structured interviews are designed to predict job performance by focusing on job-related competencies.

Why structured interviews work?

Structured interviews are renowned for their ability to predict job performance reliably by focusing on job-related competencies and minimizing biases, ensuring fair and objective candidate assessments.

Enhanced objectivity

Structured interviews minimize biases that can affect hiring decisions. By asking the same questions to all candidates, recruiters can compare responses objectively and reduce the influence of subjective factors such as personal preferences or first impressions.

Improved reliability

The consistency of structured interviews leads to more reliable results. When the same questions are asked in the same manner, it is easier to evaluate and compare candidates’ responses, ensuring that the assessment is based on relevant job criteria.

Higher validity

Research has shown that structured interviews have higher predictive validity than unstructured interviews. This means they are more effective in predicting job performance and identifying the best candidates for a role.

Legal defensibility

Structured interviews are more defensible in legal terms because they provide a clear, standardized process that can be documented and reviewed. This helps organizations demonstrate that their hiring practices are fair and non-discriminatory.

How to conduct a structured interview?

Conducting a structured interview involves meticulous preparation, from crafting job-specific questions to training interviewers on consistent evaluation techniques, ensuring a standardized and effective assessment process.

Step 1: Define the job requirements

Before conducting a structured interview, it is crucial to have a clear understanding of the job requirements. This involves identifying the key competencies, skills, and attributes needed for the role. These requirements will form the basis for the interview questions.

Identify key competencies

1. Technical skills: Specific skills required to perform job-related tasks.
2. Behavioral competencies: Traits such as teamwork, communication, and problem-solving abilities.
3. Cultural fit: Alignment with the organization’s values and culture.

Step 2: Develop interview questions

Based on the identified competencies, develop a set of standardized questions. These questions should be open-ended to encourage detailed responses and should be directly related to the job requirements.

Types of questions

1. Behavioral questions: These questions ask candidates to provide examples of past behavior that demonstrate their competencies. For example, “Can you describe a time when you had to solve a complex problem at work?”
2. Situational questions: These questions present hypothetical scenarios and ask candidates how they would respond. For example, “How would you handle a situation where you have conflicting deadlines?”

Step 3: Create a scoring system

Develop a scoring system to evaluate candidates’ responses. This system should be objective and based on predefined criteria. Each response can be rated on a scale (e.g., 1 to 5), with detailed descriptions for each rating level.

Example scoring rubric

• 1 – Poor: The candidate’s response is incomplete or irrelevant.
• 2 – Fair: The response is somewhat relevant but lacks detail or clarity.
• 3 – Good: The response is relevant and demonstrates some understanding of the competency.
• 4 – Very Good: The response is detailed and clearly demonstrates the competency.
• 5 – Excellent: The response is comprehensive and provides strong evidence of the competency.

Step 4: Train interviewers

Ensure that all interviewers are trained on how to conduct structured interviews. This includes understanding the importance of asking the same questions, using the scoring system consistently, and avoiding biases.

Training topics

1. Interview techniques: Effective questioning and listening skills.
2. Scoring consistency: How to apply the scoring system fairly.
3. Bias awareness: Recognizing and mitigating unconscious biases.

Step 5: Conduct the interview

When conducting the interview, follow the standardized format. Begin with an introduction to set the context and explain the structure of the interview. Ask each question in the predetermined order and take notes on the candidates’ responses.

Interview process

1. Introduction: Briefly introduce yourself and the purpose of the interview.
2. Structured questions: Ask each question in the same order for all candidates.
3. Note-taking: Document responses accurately to ensure a reliable evaluation.
4. Closing: Thank the candidate and provide information on the next steps in the hiring process.

Step 6: Evaluate and compare candidates

After the interviews, use the scoring system to evaluate each candidate’s responses. Compare the scores to identify the top candidates. Ensure that the evaluation process is transparent and based on the documented criteria.

Evaluation tips

1. Consistency: Apply the scoring system consistently across all candidates.
2. Team discussion: If multiple interviewers are involved, discuss the evaluations to ensure a consensus on the final scores.
3. Documentation: Keep detailed records of the scores and justifications for future reference.

Best practices for structured interviews

Implementing best practices such as thorough job analysis, clear scoring rubrics, and providing constructive feedback to candidates enhances the validity and fairness of structured interviews, optimizing candidate selection outcomes.

Continuously review and improve

Regularly review the structured interview process to ensure it remains effective and relevant. Gather feedback from interviewers and candidates to identify areas for improvement.

Incorporate diverse perspectives

Involve a diverse panel of interviewers to bring different perspectives and reduce biases. This can enhance the objectivity and fairness of the interview process.

Use technology

Leverage technology to streamline the structured interview process. Use interview software to schedule interviews, record responses, and automate scoring.

Combine with other assessment methods

While conducting interviews are highly effective, they should be combined with other assessment methods, such as skills tests or work samples, to provide a comprehensive evaluation of candidates.

Common challenges and how to overcome them

Despite their benefits, structured interviews may face challenges such as interviewer bias or difficulty in assessing complex skills; overcoming these challenges requires rigorous training, calibration sessions, and continuous refinement of interview protocols.

Bias in question development

Even with a structured approach, biases can creep into the development of interview questions. To mitigate this, involve multiple stakeholders in the question development process and review questions for potential bias.

Candidate discomfort

Candidates may find the rigid format of structured interviews uncomfortable. To address this, provide a clear explanation of the process at the beginning of the interview and ensure a welcoming and professional environment.

Interviewer fatigue

Conducting multiple structured interviews can lead to interviewer fatigue, which may affect the consistency of the evaluations. To combat this, schedule breaks between interviews and consider rotating interviewers.

Conclusion

Structured interviews are a powerful tool for recruiters, offering a fair, reliable, and valid method of assessing candidates. By following the steps outlined, recruiters can implement structured interviews effectively and enhance their hiring processes. Continuous improvement, bias mitigation, and the integration of diverse perspectives are key to maximizing the benefits of interviews. As the recruitment landscape evolves, structured interviews will remain a critical component in selecting the best talent for organizations.
