How to prepare for a behavioural interview in one evening

Behavioural interviews are predictable. The questions vary in wording but map to a handful of themes, and a small set of well-prepared stories covers almost all of them. Here is a preparation plan that fits into one evening.

Pick six stories

Choose six situations from your last few years that you can talk about in detail. Between them they should cover: a result you are proud of, a conflict you resolved, a failure and what you learned, a time you influenced without authority, a time you had to learn something fast, and a decision made with incomplete information.

Write each in four beats

Situation (one sentence), task (what you were responsible for), action (what you specifically did — the longest part), result (the number or outcome, plus what changed afterwards). Keep each story to about ninety seconds when spoken. Write them down; the act of writing exposes the stories that lack a result.

Map stories to themes

Most questions ask about leadership, teamwork, conflict, failure, prioritisation, ambiguity or customer focus. Each of your six stories will fit two or three themes. Make a small grid so you know, when a question comes, which story to reach for.

Practise aloud, with feedback

Say each story out loud at least twice. Better: run a mock interview that asks the questions in random order and scores the answers. The first pass will reveal rambling and missing results; the second pass fixes them. Thirty minutes is enough.

Prepare the two questions you will be asked

'Tell me about yourself' — sixty seconds, present, past, future, ending with why this role. 'Why do you want to work here?' — one specific thing about the company and one about the role, with a link to your experience. Both should be rehearsed until they are effortless.

Bring the stories to the interview

A page of notes with the six story titles and their key numbers is entirely acceptable in most interviews, and essential in video ones. You are not reading answers; you are reminding yourself which story to tell.

The morning after

Read the six stories once more, then stop. Over-preparation makes answers sound recited. The goal is to know your material well enough to have a conversation about it.
