A structured interview is a standardized method of candidate assessment where all candidates are asked the exact same set of pre-defined, job-relevant questions in the same order. This method is the single most reliable way to conduct interviews because it introduces objectivity into a process that is otherwise vulnerable to personal bias and “gut feelings.”
I. Why the Structured Interview Works (The Science of Fairness)
The power of a structured interview lies in its ability to isolate relevant data and minimize human subjectivity.
- Minimizes Unconscious Bias: By forcing interviewers to ask the same questions and stick to a standardized evaluation, it dramatically reduces the influence of affinity bias (hiring people who are like you) or first-impression bias.
- Keeps the Focus on Skills and Experience: The questions are specifically designed to target the core competencies and behaviors required for the job, ensuring the conversation stays focused on job relevance, not personal details.
- Helps You Fairly Compare Candidates: Because every candidate generates answers to the same questions, managers can fairly compare responses using a standardized scoring system, making the final decision data-driven rather than purely intuitive.
II. Best Practices for Implementing a Structured Interview
Transitioning from casual conversation to a structured process requires planning and consistency.
1. Design Your Interview Guide Collaboratively
- HR Partnership: Always collaborate with HR or legal counsel to build your interview guide. This ensures compliance and validates the job-relevance of the questions.
- Focus on Behaviors and Technical Skills: The most effective questions are behavioral (e.g., “Tell me about a time when…”) and situational (e.g., “What would you do if…”). Supplement these with necessary technical questions specific to the role.
2. Implement a Clear Scoring Rubric
- Define Success: For every question, create a clear scoring rubric that defines what an “Excellent,” “Good,” or “Poor” answer looks like before the interviews begin.
- Use Objective Scales: Use a consistent numerical or categorical scale (e.g., 1-5 rating) and require interviewers to document their reasoning based on the evidence provided by the candidate.
3. Avoid This Common Opening Mistake
Starting an interview with a generic, open-ended prompt like “Tell me about yourself” can lead to unintentional bias, as candidates often default to personal history, hobbies, or irrelevant background details.
- Instead, ask about specific job-related experiences: Begin with a structured, job-relevant question that immediately grounds the conversation in professional skills and past performance.
