Prison officer interview questions 2026: STAR answers

In shortThe interview is one part of a roughly 2 hour 30 minute online assessment centre, and HMPPS publishes no list of questions.

In England and Wales the interview is part of the online assessment centre, which includes an interview, a role-play scenario and a written test. It is one component of a longer stage, not a stand-alone panel. See the assessment centre guide for the whole stage.

The Ministry of Justice advert for the October 2026 HMP Birmingham vacancy says the centre assesses behaviours, strengths and abilities. Those are the best published guide to what an interviewer is looking for. They are not a list of questions; they are the lenses through which your answers are judged.

This is why a 'top 50 prison officer interview questions' list is unreliable. Nothing official confirms them. What you can do with certainty is prepare genuine examples against the published behaviours, learn a structure for delivering them and practise speaking them aloud. Every question we write is flagged as practice.

• Communicating and influencing
• Managing a quality service
• Making effective decisions
• Caring

In shortPrepare stories for behaviour questions, but answer strengths questions quickly and honestly without rehearsing them.

Behaviour questions ask for evidence of the past: 'tell us about a time when...'. You answer with a specific example, ideally structured with STAR. Strengths guidance says there are no right or wrong answers, that assessors want your initial response, and that you should not rehearse your answers.

In practice, prepare six to eight genuine stories for behaviours and know them well enough to adapt. For strengths, give a short, natural answer about what you like doing and why. Do not invent a persona; strengths questions are designed to reveal natural inclinations.

Success Profiles

The Civil Service framework has five elements: behaviours, strengths, ability, experience and technical. Not all are relevant to every role; for prison officers the advert names behaviours, strengths and abilities.

Behaviours

GOV.UK defines them as the actions and activities that people do which result in effective performance in a job.

Strengths

The things we do regularly, do well and that motivate us.

In shortThree named behaviours have published GOV.UK definitions; 'caring' is HMPPS's technical area and its descriptors are not published on the pages we read.

The how-to-apply page lists communicating and influencing, managing a quality service and making effective decisions, with a technical area of caring. The first three are Civil Service behaviours with published definitions.

Communicating and influencing

Communicating purpose and direction with clarity, integrity and enthusiasm while respecting the needs, responses and opinions of others.

Making effective decisions

Using evidence and knowledge to support accurate, expert decisions and advice and carefully considering alternative options, implications and risks.

Managing a quality service

Delivering service objectives with professional excellence, expertise and efficiency, taking account of diverse customer needs.

In shortSTAR (situation, task, action, result) is the GOV.UK-recommended structure; spend most of your time on what you personally did.

GOV.UK recommends the STAR method for describing examples: set the scene, show what and how you did, and the overall outcome. A good STAR answer lasts about two minutes spoken, which is roughly 250 to 300 words, and spends most of its time on the action.

1. Situation: one or two sentences on where, when and what was happening. Keep it specific and brief.
2. Task: what you were responsible for, or what needed to happen. Make clear it was your job to act.
3. Action: the main part. What you did, in order, and why. Show the behaviour: how you listened, weighed options, communicated, handled risk.
4. Result: the outcome, with a fact or number if you honestly have one, and what you learned or would change.
5. Link back: finish with a short sentence connecting it to the role, for example how it shows the behaviour being assessed.

In shortYou do not need prison experience, but you do need six to eight truthful examples that between them cover each behaviour twice.

HMPPS says no specific experience or qualifications are needed and that personal qualities are more important. Draw examples from work, study, volunteering, sport, family, caring or community life. One strong example can often answer several questions, so choose rich ones: situations with a challenge, other people, a decision and a real result.

Write each example on a card with STAR bullet points, tag it with the behaviours it shows, and rehearse it aloud. Do not memorise word-for-word; the goal is to know the facts so well that you can tell them naturally from any angle.

• A time you communicated something difficult or unwelcome to someone.
• A time you listened to someone who disagreed with you and changed your approach.
• A time you made a decision under pressure or with incomplete information.
• A time you improved how something was done for the people you served.
• A time you helped someone who was upset, vulnerable or struggling.
• A time you worked with a team to get something done, or dealt with a conflict.
• A time you made a mistake and what you did about it.
• A time you stayed calm when others did not.

In shortThese are our own practice questions, not HMPPS questions; if you cannot find an example for one, that is a gap to fill.

The questions below were written from the published behaviours and the HMPPS skills page. They are not taken from HMPPS, not confirmed to be asked and not ordered by likelihood. Use them to test your example bank.

In shortThese invented answers show STAR structure and level of detail only; replace every fact with your own real experience.

The answers below are fictional. They are not scripts and not model answers an assessor will recognise; copying them would be dishonest and would fail follow-up questions.

In shortAnswer strengths questions quickly, briefly and honestly; they are practice-only prompts for reflection, not predictions.

Because the advert says strengths are assessed, expect some questions that are less about 'tell me about a time' and more about what you enjoy and how you naturally work. Assessors want an initial response, so do not rehearse.

Honest answers help the match: a role with rolling shifts, nights and challenging situations suits some people more than others, and the careers site is open that the job involves dealing with stressful, traumatic and at times emotional issues.

In shortA good 'why a prison officer' answer is specific, honest and balanced, and rests on what HMPPS actually publishes about the role.

Prepare for questions about motivation and understanding of the role. Read what a day in the life looks like and the pros and cons so that your answers are grounded.

• Officers work rolling shifts including nights, weekends and bank holidays; some shifts start around 7am.
• Officers supervise around six prisoners each according to the careers site.
• Training is a 10-day induction plus a seven-week foundation course (about nine to ten weeks), with continuous assessment.
• Your role involves safety, security, supporting people in custody and helping them change.

In shortMost failed interviews come down to preparation and delivery rather than ability, so these mistakes are cheap to fix.

Most failed interviews have predictable causes. Knowing them in advance is a cheap way to improve.

In shortBecause the centre is online, delivery matters: camera, pace and pauses, and any adjustments must be arranged before the day.

HMPPS says the assessment centre is online and needs a laptop with a webcam. Pauses are fine: taking a few seconds to think is better than rushing into a muddled answer. If you need a question repeated, ask.

Nerves are normal. Practise with a friend, record yourself, or use a structured rehearsal tool. The paid Interview Toolkit lets you answer questions aloud with an AI interviewer and get feedback, and the Candidate Bundle combines it with other candidate tools; both are practice, built around the published behaviours, and neither replicates the real interview.

A free alternative is to answer the practice questions above out loud and time yourself.

In shortTwo weeks is enough for a focused plan once you have an invitation; adjust it to your date and commitments.

1. Days 1 to 2: Read the vacancy, the HMPPS how-to-apply page and the GOV.UK behaviours; write each behaviour in your own words.
2. Days 3 to 4: Brainstorm and select six to eight genuine examples; write each as STAR bullet points.
3. Days 5 to 7: Speak each example aloud, timing it to about two minutes; refine so action and result are strong.
4. Days 8 to 9: Work through the practice questions above and invent follow-up questions for each example.
5. Days 10 to 11: Reflect on strengths questions; read about the role and write a short, honest answer on why you want it.
6. Days 12 to 13: Run a full mock session on camera, including a short written exercise; fix technical problems.
7. Day 14: Rest, check equipment, re-read your invitation and plan your route to a quiet room.

In shortResults come within 3 working days; a pass moves you to pre-employment checks, and a fail means a six-month wait on the October 2026 advert.

See how long recruitment takes and vetting.

If you are unsuccessful, the October 2026 advert says a six-month waiting period applies before you can apply again. Use it: strengthen your examples, gain relevant experience, rehearse and then reapply. Our guide to reapplying after rejection sets out how, and the online assessments and application guides cover the earlier stages.
