Behavioural Interview Guide
Behavioural interviews test what you've actually done — not what you think you'd do. Here's how to structure winning answers for every type of behavioural question.
What is a behavioural interview?
Behavioural interview questions ask you to describe real situations from your past. They typically start with: “Tell me about a time when…”, “Give me an example of…”, or “Describe a situation where…”
The underlying principle is that past behaviour predicts future performance. Rather than asking “how would you handle a difficult customer?”, interviewers ask “tell me about a time you handled a difficult customer” — because the latter reveals what you actually did, not just what sounds good.
Behavioural interviews are used by almost every major employer — from early-stage startups to the Civil Service, investment banks, and global tech companies. The competencies tested vary by role, but the format is consistent. The best preparation is structured: learn the STAR framework, build a bank of strong examples, and practise delivering them.
The STAR Framework
Situation
Set the scene in 2–3 sentences. Where were you, what was the context, and why did it matter?
Task
What was your specific responsibility? What were you accountable for? Distinguish your role from the team.
Action
What exactly did you do? Use 'I', be specific about steps and decisions. This is the most important part — spend 60% of your answer here.
Result
What was the outcome? Quantify wherever possible. Include what you learned if the result was mixed.
Competencies & example questions
Most behavioural interviews test 4–6 of these core competencies. Know which ones are most relevant to your target role — they're usually in the job description.
Leadership
Tell me about a time you led a team through a difficult period.
Describe a situation where you had to influence without authority.
Interviewer tip
Show that you lead through others — not by doing everything yourself. Focus on how you motivated, delegated, and removed blockers.
Problem Solving
Give me an example of a complex problem you solved.
Tell me about a time you made a decision with limited information.
Interviewer tip
Walk through your analytical process step by step. Quantify the problem and the outcome — numbers make results credible.
Handling Failure
Tell me about a mistake you made. What did you do?
Describe a project that didn't go as planned.
Interviewer tip
Pick a real failure — not a humble brag. Demonstrate accountability, what you learned, and what you changed as a result.
Teamwork & Collaboration
Tell me about a time you worked with a difficult colleague.
Describe a successful cross-functional project you contributed to.
Interviewer tip
Use 'I' not 'we' — the interviewer is evaluating your contribution, not your team's. Credit others, but be clear about your role.
Communication
Describe a time you had to adapt your communication style.
Tell me about a time you had to deliver difficult news.
Interviewer tip
Be specific about your audience, the message, the medium you chose, and the outcome. Don't just say you 'communicated well'.
Time Management
Tell me about a time you managed competing priorities.
Describe how you handled a situation with a tight deadline.
Interviewer tip
Show your prioritisation method — how did you decide what to do first? What trade-offs did you make and why?
Customer Focus
Tell me about a time you went above and beyond for a customer.
Describe a situation where you had to manage difficult client expectations.
Interviewer tip
Link your actions to business outcomes — retention, NPS, revenue. Customer focus should be demonstrably in your values, not just your job description.
Adaptability
Tell me about a time you had to adapt quickly to a major change.
Describe a time you challenged the status quo.
Interviewer tip
Show that you embrace change rather than resist it. The best answers here demonstrate that you proactively drove the adaptation rather than simply coping.
Dos and Don'ts
Do this
Use specific numbers and metrics in your results
Pick examples with genuine stakes — not trivial situations
Practise your answers out loud before the interview
Prepare 8–10 versatile examples you can adapt to different questions
✕Avoid this
Say 'we' when you mean 'I' — own your contribution
Choose 'humble brag' failures — pick a real one with real learning
Run longer than 2.5 minutes per answer
Memorise word-for-word — know your stories, not scripts
Your preparation plan
Read the job description carefully
Identify 4–6 competencies the role requires. These will be tested.
Build your example bank
Brainstorm 8–10 strong examples from your career. Cover different competencies and choose situations with real stakes.
Structure each example with STAR
Use the STAR Generator to format each story. Time yourself — aim for 90–120 seconds per answer.
Practise out loud
Record yourself or practise with a friend. Written answers always sound different when spoken.
Prepare for follow-up questions
Interviewers often probe further: 'What would you do differently?' or 'What did you learn?' Have a ready answer.
