How to Prepare for a Job Interview (UK Guide)

To prepare for a job interview in the UK, do four things well: research the company and role, prepare four to six STAR examples for likely questions, rehearse your answers out loud, and sort out practical details like what to wear and how to join the call. That is the whole of how to prepare for a job interview— everything below is detail. The good news is that nerves are normal: a JDP survey (via StandOut CV) found 93% of people have felt interview-related anxiety at some point, so you are not the exception.

Key takeaways

• Budget time to prepare. Indeed (via StandOut CV) puts typical prep at 5 to 10 hours per interview — CV review, company research and practising answers.
• For a competency based interview, prepare distinct STAR stories, not one all-purpose anecdote.
• Interview practiceworks: in JDP's survey, 70% of respondents rehearse answers out loud and 62% prepare stories in advance.
• Have a calm reset ready for when your mind goes blank — asking for a moment is allowed.
• For what to wear to an interview, err towards formal even at casual workplaces.

How do I prepare for a job interview in the UK?

Start with research, then practice, then logistics. The National Careers Service interview guidance recommends reading the job description closely, learning what the organisation does, and preparing examples before the day. Set aside real time for it — Indeed (via StandOut CV) reports candidates typically spend 5 to 10 hours, yet only 54% actually research the company first (Indeed 2024 Workforce Insights Report, via StandOut CV). Doing the research puts you in the prepared minority.

A simple running order:

1. Read the job description and underline every skill or competency it names.
2. Research the company — what they do, recent news, their tone of voice.
3. Map likely questions to specific examples from your experience.
4. Rehearse out loud, then prepare your logistics and outfit.

It helps to know that first impressions form fast. A BPS / Psychonomic Bulletin & Review study (via Modern CV) found 60% of hiring managers decide whether you are suitable within the first 15 minutes, so your opening answers and arrival matter.

What is a competency based interview and how do I answer it?

A competency based interview(also called behavioural) asks you to evidence skills with real past examples — “tell me about a time you handled a difficult customer” rather than “are you good with customers?”. It is the dominant format in the NHS, Civil Service and large corporates, which is why so many UK candidates ask, in the words of one r/UKJobs thread, how to “get to the root of why I am so bad at” them.

The fix is structured answers and enough material. Candidates score badly for two reasons: they run out of distinct examples, and they leave out the result. On r/AskUK, people describe competency interviews as “guessing hidden criteria” and feeling forced to hit buzzwords — some report rejection specifically for “not using the STAR method”. Treat the marking criteria as the skills listed in the advert, and answer each one with a complete story.

What is the STAR method, and how many examples should I prepare?

STAR is a four-part structure for answering competency questions: Situation, Task, Action, Result. The National Careers Service describes it as setting the scene, explaining what needed doing, what youpersonally did, and the outcome — ideally with a number or measurable change.

• Situation— briefly, the context.
• Task— the problem or goal you owned.
• Action— what you did, using “I” not “we”.
• Result— the outcome, quantified where you can.

Prepare four to six varied stories rather than one per question. The reason candidates “run out of examples” is that a single project can usually be retold to show different competencies — leadership, problem-solving, dealing with conflict. The National Careers Service also advises delivering examples conversationally “so as not to appear too rehearsed”, which resolves the catch-22 people raise on r/careerguidance: prepare the structure and the facts, not a word-for-word script.

How do I answer common questions like “tell me about yourself”?

Lead with a tight, role-focused summary, not a CV read-out. Candidates on r/recruitinghell single out “tell me about yourself” as the question they dread most because there is no obvious right answer. Keep it to three beats: who you are professionally now, one relevant achievement, and why this role. For “what is your biggest weakness”, name a genuine one and the concrete step you take to manage it — the National Careers Service top-questions guidance favours honesty over a humble-brag.

Two practical points the data backs up. First, manners count: Jobvite (via StandOut CV) found 86% of recruiters would reject a candidate for being rude to staff such as a receptionist, and 71% for checking their phone mid-interview. Second, prepare two or three questions to ask at the end — it signals genuine interest and steadies your nerves. Tailoring how you frame your experience to each role is far easier when your CV already speaks the same language; you can tailor your CV to each role so your stories and your application line up.

How do I calm interview nerves and stop my mind going blank?

Rehearse out loud, and have a reset ready for the moment it happens. The single most reassuring fact here: blanking is so common that the top-voted advice in r/jobs threads about “brain fart” moments is simply to ask for a moment rather than panic-talk, or to honestly say “I don't know” and move on. Interviewers expect a short pause; they read it as composure, not failure.

The deeper fix is interview practice. In JDP's survey, 70% of respondents rehearse answers out loud and 62% prepare stories in advance — and it works, because what you have said before comes back more easily under pressure. This matters most for the nerves spiral people describe on r/UKJobs, where anxiety “gets worse with every unsuccessful interview”. Reps break that cycle. JDP (via StandOut CV) also found 41% of candidates are most nervous about not being able to answer a difficult question, which is exactly the fear practice reduces. If you want repetition with structured, real-time feedback rather than a mirror, that is the kind of AI interview practice that turns one nervous attempt into many calm ones.

What should I wear, and how do I prepare for a phone interview?

When unsure, dress smart. The recurring r/AskUK consensus is to err towards formal even for casual workplaces — you do not need a full suit, but business attire works in your favour. Budget honestly: Modern CV puts the average cost of attending a UK interview at £42, rising to nearly £100 for 16 to 24-year-olds, largely down to interview clothing.

For phone or video screening calls — which UK candidates on r/UKJobs find uniquely stressful because there is no body language to read — prepare differently:

• Have your CV and the job description in front of you.
• Stand or sit upright to steady your voice; smile, as it carries down the line.
• Treat it as a real assessment — an HR screen checks “if both sides are aligned” before a full interview.
• Let short silences sit rather than filling them nervously.

What if I am ghosted after the interview?

It is common, it is not a verdict on you, and a brief follow-up is reasonable. Being ghosted is the single most bitter complaint across r/UKJobs and r/AskUK — and the numbers bear it out: 48% of UK job seekers say they have been ghosted after an interview or late-stage application (CV-Library Candidate Behaviour Barometer 2025, via Modern CV), and 40% waited over two weeks for any response (Aptitude Research, via StandOut CV). A polite thank-you note also helps: Robert Half (via StandOut CV) found 80% of British hiring managers view one favourably, yet only 25% of applicants send one.

Common questions

How long should I spend preparing for a job interview?

Plan for several hours, not minutes. Indeed (via StandOut CV) reports candidates typically spend 5 to 10 hours per interview across CV review, company research and practising answers. Front-load the research and your STAR examples, then leave time to rehearse out loud the day before so your answers feel familiar rather than memorised.

How many STAR examples should I prepare?

Aim for four to six varied stories. Because one strong example can usually demonstrate several competencies — leadership, problem-solving, handling conflict — a small, well-chosen set covers most questions. This directly fixes the common complaint of “running out of examples” in a competency based interview, where the real issue is reuse, not a shortage of experience.

Do I need to wear a suit to a UK interview?

Not necessarily, but lean formal. The r/AskUK consensus is to err towards business attire even at casual workplaces — you do not need a full suit, but smart dress works in your favour. Factor in cost too: Modern CV puts the average UK interview at £42, rising to nearly £100 for 16 to 24-year-olds.

What do I do if my mind goes blank?

Pause and reset — it is allowed. The most upvoted advice in r/jobs threads is to ask for a moment rather than panic-talk, or to honestly say “I don't know” and move on. Interviewers read a short, composed pause far more kindly than a rushed, rambling answer.

Is it normal to be ghosted after an interview?

Unfortunately, yes. CV-Library's 2025 barometer (via Modern CV) found 48% of UK job seekers have been ghosted after an interview or late-stage application, and 40% waited over two weeks for any reply (Aptitude Research, via StandOut CV). A single polite follow-up is reasonable; beyond that, it reflects the employer, not your performance.

How do I prepare for a phone screening call?

Treat it as a genuine assessment. Have your CV and the job advert in front of you, sit upright to steady your voice, and let short silences sit. An HR screen checks whether both sides are aligned before investing in a full interview, so prepare a concise “why this role” answer and two questions of your own.
