How to Prepare for a Job Interview in the UK

Types of UK interview

Formats vary by employer and sector. You may encounter:

• Screening calls or video interviews
• Competency-based interviews (behavioural questions)
• Panel interviews with several interviewers
• Presentations or work samples
• Assessment centres (common for graduate schemes and large employers)
• Informal conversations — still interviews, even if labelled casually

Civil service roles often use structured competency frameworks — see Civil Service Interview Questions.

Research the employer

Before any interview, understand what the organisation does, who it serves, and why you are interested in this specific employer rather than the sector in general. Useful research includes:

• What the organisation does and who it serves
• Recent news, reports or public announcements
• Values, mission or strategic priorities mentioned on their website
• Culture signals — tone of communications, employee stories, reviews (treat reviews cautiously)

Aim for enough context to explain why you want to work there specifically. If you are interviewing for a public sector role, also read Civil Service Interview Questions for structured competency preparation.

Understand the role deeply

Re-read the job description and person specification. Highlight:

• Essential criteria you must demonstrate
• Desirable criteria that could differentiate you
• Repeated themes — teamwork, customer focus, analysis
• Tasks that might come up in questions

Prepare at least one strong example for each major requirement.

Prepare your examples (STAR method)

Competency questions often ask for past behaviour: “Tell me about a time when…” Structure answers with STAR:

• Situation — brief context
• Task — what you needed to achieve
• Action — what you did (focus on your contribution)
• Result — outcome, learning or measurable impact where possible

Common question types

About you and motivation

• Tell us about yourself
• Why this role and organisation?
• Why are you leaving your current role / changing career?

Competency and behavioural

• Describe a time you worked under pressure
• Give an example of resolving a conflict
• Tell us about a mistake and what you learned

Strengths and development

• What are your strengths?
• What would you improve about yourself?

Career changers should prepare a clear, positive narrative for why they are moving — linked to skills and motivation, not criticism of past employers.

Practical logistics

• Confirm time, format, location or video link
• Test technology for remote interviews — camera, microphone, background
• Plan travel with buffer time; know the building entry process
• Prepare questions to ask — about team, priorities, success in the role
• Bring copies of your CV and any requested documents
• Dress appropriately for the sector — when unsure, slightly smarter is safer

After the interview

Send a brief, professional thank-you if appropriate for the sector. Reflect on questions that caught you off guard and refine your examples. If unsuccessful, you may ask for feedback — employers are not always able to provide detailed responses.

Common mistakes

• Arriving without examples that match the person specification
• Speaking negatively about previous employers
• Giving answers that are too long or too vague
• Failing to prepare questions — it can signal lack of interest
• Not practising aloud — answers sound different spoken than written

Frequently asked questions

How long should interview answers be?

Roughly one to two minutes for most competency answers — enough detail for STAR, not a monologue. Interviewers may prompt for more if needed.

What if I have no direct example for a competency?

Use the closest relevant experience — volunteering, study, caring or community roles count if you explain the parallel honestly.

How do I prepare for a video interview?

Test camera, microphone and connection beforehand. Choose a quiet background, look at the camera when speaking, and have your notes and the job description visible but out of sight.

What should I ask the interviewer?

Prepare two or three questions about the team, priorities in the first months, or how success is measured. Avoid questions easily answered by the employer’s website.

How do career changers explain why they are moving?

Focus on what you are moving towards — skills, motivation and fit for this role — rather than criticising previous employers. Link past experience to the new direction with specific examples.

What to do next

1. Research the employer and re-read the job description
2. Build a STAR example bank matched to key criteria
3. Practise answers aloud — ideally with feedback
4. Prepare logistics and questions to ask
