The STAR interview technique, with worked examples

STAR gives you a four-step structure for answering competency-based interview questions with a true, specific story.

What the STAR technique is

STAR is a simple structure for telling a true story about something you have done. The National Careers Service sets out the four parts:

Letter	Meaning	What to say
S: Situation	The circumstances	Where you were and what was happening
T: Task	Your responsibility	What you needed to achieve
A: Action	The steps you took	What you personally did, in order
R: Result	What happened	The outcome and what you learned

Interviewers use these stories to judge how you behave in real situations, because past behaviour is a useful guide to future behaviour. The same structure also works for CV bullet points, cover letters and application forms. See our UK CV guide for how to apply it on paper.

Competency-based interview questions

Competency-based questions ask for a specific example. They often start with "Tell me about a time when...". Typical themes include:

Teamwork: a time you worked with others towards a shared goal.
Leadership: a time you guided or motivated other people.
Problem solving: a problem you faced and how you handled it.
Communication: a time you explained something to someone who found it hard to follow.
Pressure and organisation: a time you had too much to do.
Learning from mistakes: something that went wrong and what you changed.

To find the likely competencies for your interview, read the job description and note the skills the employer lists. Then prepare one example for each. The free interview question generator turns a pasted job advert into a list of likely questions to practise with.

How to prepare your examples

List five to six experiences from work, school, college, volunteering, sport or home. The National Careers Service says examples can come from any of these.
Match each experience to a skill from the job advert.
Write a few notes for each part of STAR. Do not write a script.
Say each one aloud and time it. Short and focused beats long and detailed.
Prepare for follow-up questions such as "What would you do differently?"

Speak naturally. The National Careers Service warns against sounding over-rehearsed. If you have rough notes and need help shaping them, the free STAR answer builder turns them into a structured draft that you can then put in your own words.

Where to put the weight

Most weak answers spend too long on the situation and too little on the action. Aim for roughly this split:

Situation and task together: about a fifth of your answer.
Action: about half, because this is what the interviewer is scoring.
Result: the rest, including what you learned.

Say "I", not "we". The Civil Service careers site tells applicants to describe what they specifically did, not what their team did.

Three worked examples

These answers are invented examples written for this guide. Use them to see the shape, then build your own from real experience.

Example 1: school-leaver (question: "Tell me about a time you worked in a team")

Situation: In Year 11, my football club needed to raise money for new kit, and the coach asked a few of us to organise a sponsored event.

Task: I volunteered to coordinate the event, so my job was to make sure everyone knew what they were doing.

Action: I asked each teammate which jobs they preferred, wrote a simple list of who was doing what, and set a short check-in each week. When two people both wanted to run the stall, I suggested they split the shifts. I also asked local shops if we could put up posters.

Result: The event went ahead on the date we planned, the club bought the kit, and the coach asked me to help organise the next fundraiser. I learned that people work harder when they pick their own part.

Example 2: graduate (question: "Describe a time you solved a problem")

Situation: In the final year of my degree, our four-person group project stalled because one member had left the group chat and nobody had the final data analysis.

Task: The deadline was a week away, and I needed to get the analysis finished without blaming anyone.

Action: I checked what files existed, then messaged the missing member directly and asked what was left to do. I split the remaining work into three clear parts, took the data analysis myself, and agreed a shared folder and a daily ten-minute call. I also told our tutor early that we had a risk so there were no surprises.

Result: We submitted on time. In the feedback, the tutor praised the clear structure. Since then, I set up a shared task list at the start of every group project.

Example 3: career-changer (question: "Tell me about a time you learned something new quickly")

Situation: After eight years in hospitality, I moved into an admin role where the team used a booking system I had never seen.

Task: I needed to be handling bookings independently by the end of my first month.

Action: I asked a colleague for a short walkthrough, then wrote my own step-by-step notes while doing real tasks. I checked each unusual booking with a supervisor until I understood the pattern, and I kept a list of questions to ask at the end of each day rather than interrupting.

Result: I was working without supervision within the month. My notes were later shared with the next new starter. The example also shows how customer-facing experience can transfer: I already knew how to stay calm when a customer's plans change.

Success Profiles and the Civil Service

If you apply to the UK Civil Service, you will meet "behaviours" as part of Success Profiles. GOV.UK explains that Success Profiles combine five elements: ability, technical skills, behaviours, strengths and experience. Behaviours are the actions that lead to doing a job well. They are matched to the grade of the role, and you are not asked to show every behaviour for one job. One behaviour the Civil Service gives as an example is Making Effective Decisions.

Behaviours are usually assessed through application forms, CVs or supporting statements, and may come up at interview. Both GOV.UK and Civil Service Careers recommend STAR for presenting evidence, and say examples can come from work, work experience, volunteering or a hobby. Explain clearly how your example proves the behaviour, because the person reading cannot assume your context.

Common mistakes

Choosing an example with no clear result.
Describing the team instead of your own actions.
Giving the same example for every question.
Reading from notes. The National Careers Service says you can refer to notes or write the question down, but keep it natural.
Panicking if you do not understand a question. You can ask the interviewer to repeat or explain it.
