Structured interview: asking every candidate the same questions, and why it works

A structured interview asks every candidate for a role the same set of questions, in the same order, scored against criteria agreed before anyone was interviewed. It sounds bureaucratic next to a conversation, and the research on selection methods has been consistent for decades: the conversation is close to useless as a predictor, and the structure is what makes an interview informative.

The mechanism is not mysterious. In an unstructured interview the interviewer forms an impression in the first minutes and spends the rest confirming it, asks different candidates different questions, and then compares people on evidence that was never comparable. Structure removes each of those failures in turn.

Building one

1. Write down what the role actually requires — four or five competencies, in behaviour rather than adjectives. Handles an angry customer without escalating, not good communicator.
2. Write two questions per competency, the same for everybody, asking about past behaviour: tell me about a time when. Hypotheticals invite rehearsed answers about the person somebody would like to be.
3. Agree the scoring before interviewing. What a weak, adequate and strong answer contains, in a sentence each. This is the part that gets skipped and the part that does the work.
4. Score immediately after each interview, independently, before the panel talks. Discussion first produces a group opinion rather than several observations.
5. Then compare scores and discuss the differences, which is where the useful disagreement lives.
6. Keep the notes. If a hiring decision is ever challenged, contemporaneous scored notes against agreed criteria are the difference between a defensible process and an assertion.

The rubric matters more than the questions. Any reasonable question produces useful information when everybody is scored against the same written standard; the best question in the world produces noise when each interviewer applies a private one. If you only do one thing from this article, write down what a strong answer looks like before the first interview.

What to avoid

• Brain teasers and puzzles. They measure exposure to brain teasers.
• Questions about hobbies, family, background, and anything that drifts towards protected characteristics — a legal exposure in most jurisdictions and a source of bias in all of them.
• Reading the CV aloud. Prepare from it beforehand and use the time for questions only the person can answer.
• Different interviewers asking whatever occurs to them. That is the failure mode structure exists to remove.
• Culture fit as a criterion. Undefined, it usually means resembles us, which narrows a team over time and is difficult to defend.

A realistic process for a small employer

Structure does not require a large process. A screening call against three must-haves, one structured interview of an hour, and a short practical exercise resembling the actual work covers most roles. The work sample is the strongest single addition — asking somebody to do a small version of the job predicts performance better than talking about it — provided it is short, paid if it is substantial, and the same for every candidate. The surrounding process is covered in recruitment process, and what happens after acceptance in employee onboarding checklist.

Where it lives

Ettex Forms carries the scoring sheet, so each interviewer scores independently and the results collect in one place rather than in four notebooks; the question set and rubric live in Ettex Docs, and the candidate records in Ettex Records with the offer documents covered in employment letter.

To be direct: this is not an applicant tracking system. There is no candidate pipeline, no job board posting, no CV parsing and no scheduling. For a business hiring a handful of people a year those features are overhead; above that, a dedicated product is a reasonable purchase.
