BEHAVIOURAL INTERVIEW PREPARATION

How to prepare for a behavioural interview.

Strong preparation is not memorising answers to fifty questions. It is building a focused portfolio of evidence, understanding what each question is testing and practising enough depth to handle follow-ups naturally.

Start with the role, not a generic question list

Read the job description and identify the behaviours behind the requirements. Look for themes such as ownership, stakeholder management, problem solving, leadership, pace, customer focus or dealing with ambiguity.

Then add any company framework, recruiter brief and seniority expectations. A good answer is not universally strong; it must provide relevant evidence for the role in front of you.

Build a balanced story portfolio

Most candidates need six to eight strong examples, not one story per possible question. Choose situations that give you range across outcomes and behaviours.

  • A meaningful success with measurable impact.
  • A failure or setback and what changed afterwards.
  • A difficult stakeholder or conflict.
  • A decision made with incomplete information.
  • An example of influence without direct authority.
  • A moment of leadership, improvement or customer impact.

Each story should be specific enough to survive follow-up questions and flexible enough to support more than one competency without being forced into every answer.

Structure the evidence with STAR

Use Situation and Task to establish context and responsibility. Spend most of the answer on Action: your decisions, alternatives, influence and response to obstacles. Finish with a credible Result and, where useful, what you learned or changed.

The structure should make your evidence easier to follow, not turn the answer into a script. Prepare prompts, key facts and metrics rather than memorising complete sentences.

Prepare the non-STAR questions too

Behavioural interviews often include motivation and career narrative questions. Prepare concise answers to “Tell me about yourself”, “Why this company?”, “Why this role?” and “Why are you considering a move?”

These answers should connect logically. Your background, reason for moving and interest in the opportunity should sound like one credible decision rather than four separate scripts.

Practise the follow-up, not only the opening answer

Interviewers may ask what alternatives you considered, how you measured success, what you personally owned, what went wrong and what you would do differently. These questions test the reliability and depth of your evidence.

Practise with changing questions and interruptions. If you can only deliver a story in one exact order, you have memorised it rather than mastered it.

A practical seven-day preparation plan

  1. Day 1: analyse the role and likely competencies.
  2. Day 2: select six to eight candidate stories.
  3. Day 3: map each story to themes and evidence gaps.
  4. Day 4: structure the strongest examples and verify facts.
  5. Day 5: prepare motivation and career narrative answers.
  6. Day 6: practise aloud with unplanned follow-ups.
  7. Day 7: run a realistic mock and refine only the weak areas.

The goal is not to predict every question. It is to make your strongest evidence easy to retrieve, adapt and explain under pressure.

Frequently asked questions

How long should a behavioural answer be?

Many answers work well in roughly two to three minutes, but complexity and interviewer style vary. Prioritise relevance and leave space for follow-up questions.

Can I use the same story more than once?

Yes, when the emphasis genuinely changes, but excessive repetition makes your experience look narrow. A balanced portfolio gives the interviewer more evidence.

Should I memorise my answers?

No. Memorise the facts, sequence and decisions. Exact wording usually makes delivery less natural and makes interruptions harder to handle.

Turn your experience into evidence you can use.
