How to conduct a structured interview: a step-by-step guide

A structured interview means every candidate for a role is judged on the same skills, through questions about what they have actually done, and every rating is backed by a note of what you heard. It is the simplest way to make interviews fair, comparable and far less dependent on gut feel.

Most interviewers are never formally trained for this. They learn by watching seniors, ask whatever comes to mind, and decide in the first few minutes. This guide gives you a repeatable method you can use from your very next interview.

Step 1 — Plan the role before you meet anyone

Before the first candidate walks in, decide what you are actually hiring for. Write down four or five skills that decide success in this job, and one line on what "good" looks like for each.

For a Sales Manager, for example, you might choose: planning a territory and pipeline, handling monthly targets under pressure, leading a small team, and building long-term customer relationships. Your list will be different for every role — that is the point.

Keep this list in front of you. Every question you ask should help you judge one of these skills. If a question does not, drop it.

Step 2 — Ask about the past, not hypotheticals

"What would you do if a client got angry?" invites a rehearsed, ideal answer. Anyone can describe what they would do. What predicts the job is what they did.

Use the same core questions for every candidate for the role, in roughly the same order. You can change the follow-ups — that is where your skill as an interviewer shows — but the starting point stays the same, so candidates can be compared fairly.

Step 3 — Probe until you hear what they actually did

First answers are usually general: "We improved collections", "I am a team player". That is not evidence yet. Your job is to turn it into a specific example with three follow-ups:

1. What did you do? — move from "we" to "I".
2. What was the result? — ask for the number, the outcome, the date.
3. What would you do differently? — shows self-awareness and learning.

Stay polite and curious, not suspicious. A good candidate enjoys being asked for detail; a weak story gets thinner the more you ask. Note the moment it gets thin — that is useful information.

Step 4 — Score every skill, with one line of evidence

Rate each skill on a simple 1–5 scale after the interview, not during the first five minutes. Next to every rating, write the exact line the candidate said that justifies it.

This one habit changes everything. It stops one strong answer from colouring every rating, it makes your decision explainable to your manager or HR, and it lets two interviewers compare notes on facts instead of impressions.

Common mistakes to avoid

• Deciding in the first five minutes — and then spending the rest of the interview confirming it.
• Talking more than the candidate — aim for them to speak most of the time.
• Leading questions — "You must be good with targets, right?" tells them the answer.
• Same rating for every skill — real people are uneven; your scorecard should be too.
• No notes — memory fades by the next candidate; evidence does not.

Why reading this isn't enough

You now know the method. The hard part is doing it live: keeping your questions on track, noticing a vague answer in the moment, and probing without sounding like an interrogation. That only improves by doing it — ideally against a candidate who does not make it easy, and with honest feedback on how you interviewed.

A simple checklist for your next interview

1. Four or five skills written down, with what "good" looks like.
2. One past-behaviour question ready for each skill.
3. Three follow-ups ready: what did you do, what was the result, what would you change.
4. A 1–5 rating and one evidence line for every skill.
5. Decision made on the scorecard, not on the first impression.

Structured interviewing is a skill, and like any skill it improves with repetition and honest feedback.
