STAR Interview Method: How to Answer Competency Questions

You've done the work. You just can't tell the story in two minutes.

For most experienced people that's the real problem in interviews. It isn't a shortage of examples. After 10, 15 or 20 years you have more than enough. It's the way they come out: several minutes of background, a lot of "we", and an ending that fades before anyone hears what changed.

The STAR interview method fixes that. This guide explains what it is, how it fits UK competency-based interviews, three examples rewritten from weak answers, and the questions to prepare for.

What is the STAR method?

The STAR method is a way to answer competency and behavioural interview questions in four parts: Situation, Task, Action and Result. It gives your example a clear shape, so the interviewer can follow it and score it.

The STAR interview method and competency-based interviews

Competency-based interviews are common in the UK, particularly in the public sector and in large organisations. The questions usually start with "Give an example of when you…" or "Tell me about a time…", and the interviewer is listening for evidence of specific skills such as leadership, decision-making or handling conflict.

STAR is the standard way to answer them, because it makes the evidence easy to find.

How the STAR method works

• Situation: where you were. One sentence of context.
• Task: what you were responsible for, or the problem you owned.
• Action: what you did. This should be most of your answer.
• Result: what changed as a result, with a number if you have one.

Keep the setup short, make the action the longest part, and always finish with the result.

Why experienced candidates' answers go wrong

The same three mistakes come up again and again:

1. Too much situation. The background matters to you because you lived it. The interviewer only needs enough to follow along.
2. "We" instead of "I". Crediting your team is usually right. In a competency interview it hides the one thing being assessed: what you did.
3. No result. The answer stops at the action or ends with "and it went well". Without a result, there's nothing for the interviewer to score.

STAR method examples

Max, Career Elevator's career coach, rewrote each of these after asking one question. The people are made up for illustration.

Example 1: "Give an example of when you influenced people you didn't manage"

Hannah, a Senior Product Manager in Manchester with 12 years' experience, spent her first 90 seconds on a restructure, two teams and the history between them.

Max's one question: "What did you do, in one sentence?"

Her STAR answer:

• Situation: Sales and engineering couldn't agree on the next quarter's roadmap.
• Task: I owned the roadmap but managed neither team.
• Action: I ran a two-week pilot with five customers and shared the results with both department heads.
• Result: They agreed one plan. It launched a month early, and all five pilot customers renewed.

Example 2: "Tell me about a time something went wrong"

Stuart, a Plant Manager in Sunderland with 19 years' experience, said: "We had a launch that didn't go well. The team struggled. We learnt a lot."

Max's one question: "What was your call, and what changed afterwards?"

His STAR answer:

• Situation: We were launching a new product line to a tight deadline.
• Task: I decided how quickly to change over the line.
• Action: I rushed it and we lost two days of output. I took responsibility with my director, then introduced a mandatory pilot shift before every changeover.
• Result: The next four changeovers ran with no lost output.

Example 3: the story that starts on your CV

Fiona, Head of Customer Service in Edinburgh with 16 years' experience, had this on her CV:

Improved customer satisfaction.

That line can't become a story, because there's no result in it.

Max's one question: "From what, to what, and how?"

The rewritten CV line:

Raised customer satisfaction from 71 to 89 in a year by rebuilding the escalation process.

The STAR story behind it:

• Situation: Satisfaction scores had been flat for two years and escalations kept building up.
• Task: I was brought in to turn it round within a year.
• Action: I mapped every escalation route, cut them from seven to three, and gave frontline advisers the authority to resolve refunds up to a set limit.
• Result: Satisfaction rose from 71 to 89 in twelve months.

Strong STAR examples usually start from a CV line with a real result in it. If the line is vague, the story will be too.

Competency questions to prepare for

These come up regularly in competency-based interviews. Have a STAR example ready for each:

• Give an example of when you disagreed with your manager.
• Tell me about a time something went wrong.
• Describe a change you led that people resisted.
• Give an example of a decision you made without all the information.
• Tell me about a time you dealt with a difficult stakeholder.
• Describe a time you had to deliver bad news.
• What achievement are you proudest of?

Six to eight strong examples, each with a clear result, can be adapted to cover most competency questions.

How long should a STAR answer be?

A common guideline is about two minutes. If you're going past three, the situation is nearly always too long. Cut the background to a sentence and let the interviewer ask for more.

How to prepare your STAR examples

1. Read through your CV and pick the six to eight lines with the strongest results.
2. For each, write one sentence for the situation, one for the task, three or four for the action and one for the result.
3. Say each one out loud and time it.
4. Check every example for "we" and change it to "I" wherever the decision was yours.
5. Make sure each one ends on a result you can say in a single breath.

If you can't find six lines with real results on your CV, start there. An interview example can only be as specific as the line it comes from. Our CV tips guide shows how to turn duties into achievements with a number.

FAQ

What is the STAR method?

The STAR method is a way to answer competency and behavioural interview questions in four parts: Situation, Task, Action and Result.

What is a competency-based interview?

It's an interview built around questions that ask for real examples of how you've behaved at work, such as "Give an example of when you…". They're common in the UK, particularly in the public sector and large organisations, and STAR is the standard way to answer them.

How long should a STAR answer be?

A common guideline is about two minutes. Keep the situation and task brief, spend most of your answer on what you did, and finish with a clear result.

Should I say "I" or "we" in a competency interview?

Say "I" for the parts that were your decisions and actions. Interviewers are assessing you, so "we" makes it hard for them to credit you with anything.

What if I don't have a number for the result?

Give the most specific outcome you can: a decision that was made, a deadline that was met, a problem that stopped happening, or feedback you received. A clear outcome without a number is better than a vague one.

Your STAR examples start on your CV

The Free Career Audit isn't interview coaching, but it works on the part your examples come from. In your Free Career Audit, Max asks what you want next, finds the one vague line on your CV, asks you one sharp question about it, and rewrites that line with you. Get the result into that line, and you have the start of a STAR example.
