Police, Fire Service and Security Interview Guide (UK): Competency Questions, Assessments and Tips
Uniformed and security roles have some of the most structured selection processes in the UK. They can feel long, but they are fair and predictable, and candidates who understand them usually do much better than those who arrive hoping for the best.
How selection normally works
Police forces, fire and rescue services and prison services typically run a multi-stage process: online application, online assessment (situational judgement and behavioural tests), an assessment centre with role plays and an interview, then fitness, medical and vetting checks. Private security roles are usually quicker, with one interview and checks such as an SIA licence and references.
Values and competencies
The police use the Code of Ethics and a competency and values framework. Fire services assess against role-related behaviours and core values. Expect themes such as public service, integrity, respect, impartiality, resilience, working with others and decision making. Read your force or service's published values and match your examples to them.
Typical questions
Why do you want to join this force or service?
Tell me about a time you dealt with a difficult or aggressive person.
Describe a time you had to make a decision under pressure.
How would you treat someone who is very different from you?
What would you do if a colleague did something unethical?
Role plays and scenarios
In role plays you may play an officer dealing with a member of the public. Stay calm, introduce yourself, listen, explain what you are doing and why, and keep your tone respectful. Assessors want to see de-escalation and clear communication rather than force or bluster.
Integrity questions
If asked what you would do about a colleague who is behaving wrongly, the safe and honest answer is that you would not ignore it. You would raise it through the proper route, and you would recognise how hard this can feel. Be honest about any difficult moments in your own past that vetting may reveal.
Fitness and wellbeing
Fire and police roles include physical tests, and prison and security roles often require reasonable fitness. Train for the specific test well beforehand, because standards are strict.
For security officers
Show reliability, vigilance and good judgement. Talk about patrolling, access control, reporting incidents and keeping accurate records. Mention your SIA licence and any first aid or conflict management training.
Common mistakes
Saying you want the job for excitement.
Telling stories where you acted alone instead of working with others.
Being unprepared on the service's values.
