The Problem with "Going with Your Gut"
Most hiring managers rely heavily on intuition when evaluating candidates. They form impressions within the first few minutes of an interview and spend the rest of the time confirming those impressions — a phenomenon known as confirmation bias. The result is hiring decisions that feel right but often aren't.
Research in organisational psychology consistently shows that unstructured interviews — where questions vary from candidate to candidate and scoring is informal — are weak predictors of actual job performance. Structured interviews, by contrast, are one of the most reliable tools available.
What Is a Structured Interview?
A structured interview has three key characteristics:
- Standardised questions: Every candidate is asked the same questions, in the same order.
- Predetermined scoring: Answers are evaluated against a consistent rubric, not personal impression.
- Multiple interviewers: Ideally, more than one person evaluates each candidate to reduce individual bias.
This consistency makes it possible to objectively compare candidates and defend hiring decisions if they're ever questioned.
Two Types of Structured Interview Questions
1. Behavioural Questions
Behavioural questions ask candidates to describe how they've handled situations in the past. The logic: past behaviour is the best predictor of future behaviour.
Formula: "Tell me about a time when you [did X]. What was the situation, what did you do, and what was the outcome?"
Examples:
- "Tell me about a time you had to manage a project with a tight deadline. How did you prioritise?"
- "Describe a situation where you disagreed with a colleague. How did you handle it?"
- "Give me an example of when you identified a problem before it became serious."
2. Situational Questions
Situational questions present a hypothetical scenario and ask what the candidate would do. These are useful for assessing judgment and values in candidates with less direct experience.
Example: "Imagine you're halfway through a project and you realise the initial approach isn't working. You have three days until the deadline. What would you do?"
Building a Scoring Rubric
Without a scoring rubric, interviewers default to gut feeling — even with consistent questions. A simple rubric might use a 1–5 scale for each question, with anchor descriptions:
| Score | Description |
|---|---|
| 1 | Response was vague, irrelevant, or showed poor judgment |
| 2 | Partial answer with limited self-awareness or insight |
| 3 | Adequate response; met the basic expectations for the question |
| 4 | Strong response with clear examples and good reflection |
| 5 | Exceptional answer; clear evidence of outstanding competency |
Each interviewer scores independently before group discussion to avoid anchoring bias (where one person's strong opinion influences everyone else).
How Many Questions Should You Ask?
For most roles, a structured interview of 6–10 questions over 45–60 minutes strikes the right balance. Focus questions on the 3–5 core competencies most critical for success in the role, with 1–2 questions per competency.
Making the Most of the Panel
When using a panel, assign each interviewer specific question areas to reduce overlap and fatigue. For example:
- Hiring manager: Technical skills and role-specific experience
- Team peer: Collaboration and communication style
- HR representative: Culture alignment and motivation
Common Mistakes to Avoid
- Asking leading questions that telegraph the "right" answer
- Letting one enthusiastic panellist dominate the debrief
- Scoring during the interview instead of immediately after (distraction reduces accuracy)
- Skipping the rubric for "obvious" hires — bias is most potent when we're certain
Final Thoughts
Structured interviews require more upfront preparation than winging it, but the payoff is significant: more confident decisions, fairer processes, and better hires. Start by structuring your next interview with just five consistent questions and a simple scoring sheet — you'll feel the difference immediately.
