The STAR method for interview answers, and where people go wrong with it
6 min read · Reviewed 19 Sept 2026
Behavioural interview questions begin with “Tell me about a time when…” or “Give me an example of…”. They are based on a simple idea: what you did in the past is the best available evidence of what you will do in the future. The interviewer wants a specific, true story. STAR is a way to tell it so that nothing important is missing.
The four parts
- Situation
The context: where, when, and what was at stake. Two sentences.
- Task
Your responsibility in that situation. One sentence. It answers the question: why was this your problem?
- Action
What you did, step by step. This is the evidence the interviewer is looking for.
- Result
What happened because of your actions, with a number if possible, and what you learned.
Get the proportions right
The most common failure is a long situation and a short action. For a 90-second answer, a good target is about 15 seconds on the situation, 10 on the task, 45 on the actions and 20 on the result. If you are halfway through and have not yet said “I” followed by a verb, you are spending too long on the background.
“So at my last company we had this big client, a very important one, and they were always changing requirements, and the deadline was very tight, and the whole team was under a lot of stress, there were many late nights… and in the end we delivered and the client was satisfied.”
“Last spring, our biggest client moved a deadline forward by two weeks. I was leading the delivery. First, I listed every remaining task and asked the client which three mattered most for their launch. Then I moved two people from a lower-priority project for ten days, with my manager's agreement. I also replaced our weekly call with a ten-minute daily one, so that questions were answered the same day. We delivered the three priority items on the new date and the rest nine days later. The client extended the contract for another year.”
Language that helps
- Use the past simple for actions: “I listed”, “I asked”, “I moved”. Avoid “I would usually…”, which turns a story into a general habit.
- Use sequence words: first, then, after that, as a result.
- Say “I” for your own actions and “we” for the team's result. Interviewers often stop candidates to ask, “but what did you do?”
- Use numbers, even approximate ones: “about a third”, “from five days to two”.
Common mistakes
- Answering with a general statement (“I always stay calm under pressure”) instead of one specific occasion.
- Choosing a story in which you were a spectator.
- Leaving out the result, or ending with “and it went well”.
- Sounding memorised. Learn the four points of each story, not the sentences.
- Inventing details. Interviewers ask follow-up questions, and invented stories fall apart on the second question.
Prepare a small library of stories
Five or six stories cover most behavioural questions: a hard problem, a disagreement, a mistake, leading without being asked, delivering under pressure, and learning something new. Write four bullet points for each, and then practise telling each one out loud in about 90 seconds. The same story can often answer several different questions if you change which part you emphasise.
