A job interview is a structured conversation with one aim: helping the interviewer judge whether you can do the job and would do it well there. Your task is to make that judgement easy with clear, specific, honest evidence.
Most interviewers now use structured, behavioural questions — “Tell me about a time when…” — because past behaviour is one of the better predictors of future performance. That's good news: it means preparation works.
Key takeaways
- Use STAR for any “tell me about a time” question, and spend most of your time on the Action.
- Say “I”, not “we” — they're hiring you.
- Quantify results where you honestly can.
- Prepare 6–8 flexible stories that cover the job's key requirements.
Structures that work
The STAR method
The standard structure for behavioural interview answers.
- 1
Situation — Brief context: where, when, what was going on (1–2 sentences).
- 2
Task — Your responsibility or the goal.
- 3
Action — What you specifically did, step by step. This is the heart of the answer.
- 4
Result — The outcome — with a number if possible — and what you learned.
Example“Our clinic's patient waiting times had doubled over a winter (situation). As shift lead, I was asked to find a fix within a month (task). I mapped a week of appointments, found that two slots a day were double-booked by the old system, and worked with reception to set up a new booking rule and a daily check (action). Average waits fell from 40 to 18 minutes, and we kept the process after I moved teams (result).”
CAR (Challenge – Action – Result)
A shorter STAR for quick answers or follow-up questions.
- 1
Challenge — The problem you faced.
- 2
Action — What you did.
- 3
Result — What changed.
Prepare a story bank
Read the job description and list its five or six most important requirements. For each, prepare one real story using STAR. Many stories can be adapted to several questions — a project that went wrong can show problem-solving, resilience and teamwork.
- A success you're proud of
- A mistake or failure and what you changed
- A conflict or disagreement you resolved
- A time you led or influenced others
- A time you learned something quickly
- A time you handled pressure or a deadline
Common questions and how to approach them
“Tell me about yourself”: use Present–Past–Future in about 60–90 seconds, ending with why this role fits.
“What's your greatest weakness?”: pick a real, non-critical weakness and show what you're actively doing about it.
“Why do you want to work here?”: be specific about the organisation — its work, values or customers — and connect it to your experience.
“Where do you see yourself in five years?”: show ambition that fits the path this role offers.
“Do you have any questions for us?”: always yes. Ask about the team, what success looks like in the first six months, or the biggest challenge in the role.
Get the length right
Most answers land best at 60 seconds to two minutes. Shorter can feel thin; much longer loses the interviewer. Lead with the answer, give the evidence, and stop. If they want more, they'll ask — follow-up questions are a good sign.
Delivery and body language
Pausing briefly before answering looks thoughtful. Keep a steady, natural eye line — looking away occasionally while thinking is normal, but frequent gaze aversion is often read less favourably. In video interviews, look at the camera when making key points and make sure your face is well lit and centred.
Be honest and specific
Never invent experience or numbers. Interviewers probe details, and specificity is exactly what makes an answer credible. If you don't have direct experience, say so and describe the closest relevant example or how you'd approach it.
Common mistakes and how to fix them
| Mistake | Fix |
|---|---|
| Saying “we” throughout | Be clear about your own contribution. |
| Long situations, short actions | Keep context to two sentences; spend 60% of the answer on Action. |
| No result | Always finish with the outcome and what you learned. |
| Generic answers | Use real names of tools, numbers, and specific moments. |
Practice drills
STAR in 90 seconds
Answer one behavioural question out loud with a timer. Aim for 15 seconds of Situation/Task, 60 of Action, 15 of Result.
Role-matched practice
Add a real job description to JobReady and practise interview questions generated from its requirements.
The follow-up drill
After each answer, ask yourself “why?” and “how exactly?” — then answer those too. That's what good interviewers do.
Practise job interview answers with instant feedback
Answer realistic questions for your role, one at a time, and get a score and a stronger version of every answer.
What the research says
Structured interviews — with consistent, job-related questions — predict job performance considerably better than unstructured ones.

Reviews of structured-interview research recommend behavioural and situational questions, which is why STAR-style preparation pays off.

In interview-style studies, speakers who averted their gaze were generally rated less favourably than those who kept a normal level of eye contact.

Frequently asked questions
How many STAR stories should I prepare?
Six to eight flexible stories usually cover most behavioural questions for a role.
How long should an interview answer be?
Usually 60 seconds to two minutes. Lead with your answer, then give your evidence.
What if I don't have work experience for a question?
Use examples from study, volunteering or personal projects, and be clear about the context. Transferable examples count.
