Interview prep (UK)
How UK interviews really work in 2026. The questions, the structure, and the prep block that gets you offers. Not generic US-imported advice.
Reviewed by Anthony, founder · Updated
Most UK interviews now follow one of three patterns: a panel using STAR (NHS, public sector), a behaviour-based panel with strengths (Civil Service), or a multi-stage mix in the private sector. Knowing which you're walking into halves your prep time.
The 7 questions you must rehearse
You will be asked some version of each of these. Practise the answers out loud, not in your head.
- 01
Tell me about yourself.
A two-minute summary, not a life story. Most common opener; most fumbled answer. Practise out loud.
Structure
Now, then, why this role. 30 seconds on each.
- 02
Why do you want to work here?
Generic answers fail. They want one specific reason: recent project, value, news, service line.
Structure
One specific fact plus how it ties to your career.
- 03
Tell me about a time you handled a conflict.
Behavioural / STAR question. Pick a real example with a constructive outcome.
Structure
Situation, Task, Action (lead with I), Result.
- 04
What's your biggest weakness?
Real weakness plus a concrete thing you're doing about it. Avoid disguised-strength cliché ("I'm a perfectionist").
Structure
Weakness, impact, action you're taking.
- 05
Where do you see yourself in 5 years?
Ambition that's plausible for this employer. Not "in your job" (lazy joke).
Structure
Skill / progression goal plus how this role moves you there.
- 06
Why are you leaving your current role?
Forward-facing, not bitter. Even if true, never trash your current employer.
Structure
What this role offers that yours doesn't (responsibility / scope / sector).
- 07
Do you have any questions for us?
You must have questions. Three minimum, specific to the role.
Structure
Team, role, business question (in that order). Save salary for offer stage.
STAR format (the UK panel default)
UK panels, especially NHS and Civil Service, score behavioural answers against STAR. Hit all four elements or you lose marks.
Situation. One sentence of context. Where, when, what was happening.
Task. What specifically you needed to do or change.
Action. The actions you took. Lead with "I", not "we". This is where most marks live.
Result. Measurable outcome. Numbers, recognition, learning, what changed.
Sector-specific notes
NHS
Panel of 2-4: a senior clinician, line manager, sometimes HR or service user.
Scored against the person specification by criterion.
Expect scenario questions on clinical prioritisation, safeguarding, deteriorating patients, MDT working.
Bring your professional registration card (NMC, GMC, HCPC). Some panels ask.
Civil Service
Behaviour-based. Three to five behaviours named in the advert, each with a grade-level definition.
At least one STAR question per behaviour.
Strengths section: shorter answers, scored on energy and authenticity not content.
Technical section if the role is technical (analyst, policy, finance).
Private sector
Usually 2-4 stages: HR screen, hiring manager, technical / panel, exec.
First stage is conversational and competency-based. Later stages get specific.
Senior / leadership roles include a presentation or case study task.
Tech roles include live coding / system design / take-home.
The 4-hour prep block
- 01
30 mins. Research the employer. Annual report, recent news, the team's LinkedIn, glassdoor.
- 02
30 mins. Research the role. Re-read the job ad and your CV side by side. List five things in your CV that match it.
- 03
90 mins. Write STAR answers for 6-8 behaviours. Communicating, Leading, Delivering at Pace, Working Together, Seeing the Bigger Picture, Managing a Quality Service.
- 04
30 mins. Prepare your three questions. One on the team, one on the role, one on the business.
- 05
60 mins. Rehearse out loud. Ideally with someone. If alone, record yourself on your phone. You will hear your own filler words.
Common mistakes
Rambling. A 90-second answer beats a 4-minute one.
"We" instead of "I". The panel scores you, not your team.
No questions at the end. Reads as not interested.
Salary in early stages. Save for offer.
Bashing your current employer. Says more about you than them.
Generic "why this employer". If you couldn't paste your answer into another company's interview, you didn't research enough.

Frequently asked
How long should I spend preparing?+
Three to four hours per interview, spread across two days. Day 1: company research, role research, list likely questions. Day 2: write STAR answers for 6-8 behaviours, rehearse out loud (with someone if possible), prepare your own three questions.
What is STAR format?+
Situation, Task, Action, Result. The standard structure for behavioural answers in UK interviews. Most NHS and Civil Service panels score you against STAR explicitly, ticking off each element. Lead with "I", not "we". The panel scores your actions.
How is an NHS interview different from a private sector one?+
NHS interviews are panel format (2-4 people), more formal, scored against the person specification by criterion, and almost always behavioural with STAR. Private sector interviews vary wildly. Could be a single conversational chat, a presentation, a case study, or a multi-stage process with HR plus hiring manager plus skip-level.
How is Civil Service interview different?+
Civil Service interviews assess against the behaviours named in the advert. Usually three to five, each with a grade-level definition (e.g. "Communicating and Influencing, Level 4"). You'll be asked at least one STAR question per behaviour. Strengths-based questions (assessed via tone and energy) often come second.
What if I don't know an answer?+
"Can I have a moment to think?" is a perfectly acceptable sentence. Better than rambling. If you genuinely don't know a technical answer, say so honestly and walk through how you'd find out. That demonstrates curiosity, not weakness.
Should I prepare answers for technical questions?+
Depends on the role. For software / data / clinical roles, expect a technical screen. Read the job ad for the specific skills named. For NHS clinical roles, expect scenario questions on prioritisation, safeguarding, and clinical reasoning at the grade above your current.
