This guide is about applying for jobs in the UK.

You have the invitation, and then a second line stops you cold: "this will be a panel interview" or "please allow half a day for the assessment centre". The questions you prepared still matter, but suddenly the shape of the conversation is unfamiliar, and the format itself feels like a new thing to get wrong.

It need not. Every format below is built to measure the same handful of things, just through a different lens. Once you can read what a given type of interview is testing, you can prepare for the lens rather than the surprise. This guide sits under our wider guide to interview questions and answers, which covers what to say; here we cover the room you say it in.

What is an interview, and why the format matters

So, what is an interview at its core? It is a structured conversation in which an employer gathers evidence on three things: can you do the role, would you do it well there, and will the team want to work with you. It is a sampling exercise, not a pass-or-fail exam, and the format an employer chooses is a clue to which of those three they most want to sample.

That is the useful reframe. The types of job interview are not random hurdles. A phone screen samples basic suitability cheaply before anyone invests an hour. A competency interview samples how you actually behaved in the past. An assessment centre samples how you work alongside other people in real time. Read the format, and you read the employer's priority, which tells you what to over-prepare.

One more thing worth saying early. UK hiring now runs in several stages as standard, and each stage tends to use a different format. So you are rarely preparing for one interview type. You are preparing for a short sequence of them, each with its own emphasis, and the rest of this guide takes them in roughly the order you meet them.

The main types of interview you will meet

There are dozens of interview kinds in the wild, but a UK job seeker in 2026 will meet the seven below far more than any others. For each, here is what it is, what it really tests, and the one habit that handles it.

The phone screen

A short call, often 15 to 30 minutes, usually with a recruiter rather than the hiring manager. It exists to filter, so the questions are logistical: right to work, notice period, salary expectations, and a quick "why this role". The tell is that the recruiter is deciding whether to pass you up the chain, and they will summarise you in two sentences when they do.

Handle it by being clear and quotable. Stand up if it helps your energy, keep your CV and the job advert in front of you, and have a one-line salary range ready so the question does not catch you flat. Brevity wins here, because the screen rewards candidates who answer the question asked and stop.

The video interview

Now the default for first interviews, and increasingly for whole processes. There are two flavours: a live video call, which behaves like an in-person interview through a screen, and a one-way recorded interview, where you answer set questions to a camera with no interviewer present. The second is the one people fumble, because there is no human reaction to read.

The strongest video interview tips are unglamorous and physical. Look at the camera lens, not your own face, so you appear to make eye contact. Raise the camera to eye level and light yourself from the front. Test the link and microphone the day before, not five minutes before. For the recorded format, the best video interview practice is to record yourself answering a question and watch it back once, which is uncomfortable and more useful than an hour of silent rehearsal.

The panel interview

Two to five interviewers at once, common in the public sector, on graduate schemes, and for senior roles. It feels like being outnumbered, and that feeling is the main thing to manage, because the content is usually standard competency questions shared out among the panel.

The habit that handles a panel is deliberate eye contact. Answer the person who asked, then bring your gaze across the rest of the panel as you speak, and return to the asker to close. Get everyone's name at the start and use them. Treat a quiet panellist as an ally rather than a threat, because the silent one is often the decision-maker taking notes.

The competency interview

The behavioural core of most UK processes, built on the premise that past behaviour predicts future behaviour. You will hear "give me an example of a time when" and "describe a situation where". It is the most predictable interview type to prepare for, because the competencies being tested are usually listed in the job description.

The structure that answers it is STAR: Situation, Task, Action, Result. Set the scene briefly, state what you were responsible for, describe what you personally did, and finish on a concrete result. The single most common failure here is answering with what the team did rather than what you did, so keep the "I" load high.

A STAR answer, worked through

"Give me an example of a time you handled a difficult deadline."

"Our largest account moved a launch forward by three weeks (situation). I was responsible for coordinating the four people producing the assets (task). I cut the review rounds from three to one, moved our check-ins to mornings, and dropped two tasks that would not affect the launch (action). We shipped two days early, and the trimmed process became our standard playbook afterwards (result)."

Notice the result is specific and the actions are clearly the candidate's own. That is what separates a competency answer that lands from one that drifts.

The technical interview

Used wherever the role needs a demonstrable skill: a coding exercise for engineers, a case study for consultants, a portfolio walk-through for designers, a written task for analysts. It tests the skill directly, but it also tests how you think when you are stuck, which many candidates forget.

Handle it by narrating your reasoning out loud. Interviewers in a technical setting care more about your approach than a flawless final answer, so talk through your assumptions, ask clarifying questions before you start, and if you hit a wall, say what you would try next rather than going silent. Treat the task as a collaboration, not an exam invigilated in silence.

The assessment centre

The heavyweight format: half a day to a full day, several exercises, multiple assessors, and often other candidates present. A typical interview assessment center day combines a group exercise, an individual presentation, a competency interview, and sometimes a written or numerical test. It tests stamina as much as skill, and consistency across exercises matters because assessors compare notes at the end.

The mistake is to treat the day as one event. Prepare each component separately, the way you would prepare each interview type on its own, then accept that you will not be brilliant at every station. Assessors look for a steady, collaborative thread across the whole day rather than one standout moment, so pace yourself and stay generous with the other candidates, who are not your direct rivals in the scoring.

The informal interview

A coffee, a casual chat, or a "let's just have a conversation" framed as low stakes. It rarely is. The relaxed setting is itself a test of judgement, and offhand remarks made over coffee can carry as much weight as a formal answer.

Handle it by staying professionally warm rather than fully off-duty. Prepare as you would for any interview, keep your examples ready, and resist the pull to overshare just because the tone is friendly. The interviewer is still gathering evidence, so let the format relax without letting your preparation relax with it.

Which format signals what

Reading the format back to its purpose is the fastest way to prepare well, so here is the mapping in one place. Each interview type points at a different thing the employer wants to measure, and your preparation should follow that pointer.

Use the panel below to match the invitation in your inbox to the thing it is really testing, and to the one habit that handles it.

Early-stage formats: phone and video

Phone screen tests basic suitability and logistics. Habit: be brief, be quotable, have a salary range ready.

Video interview tests the same things as an in-person first round, plus your setup. Habit: look at the lens, light yourself from the front, and test the link a day early.

Core-stage formats: competency, panel and technical

Competency interview tests past behaviour against the job description. Habit: answer in STAR, and keep the "I" load high.

Panel interview tests the same content under social pressure. Habit: use names, move your eye contact across the room, return to the asker.

Technical interview tests a demonstrable skill and how you reason when stuck. Habit: narrate your thinking out loud.

Late-stage and outlier formats: assessment centre and informal

Assessment centre tests stamina and how you work with others across a day. Habit: prepare each exercise separately, stay collaborative throughout.

Informal interview tests judgement under a relaxed surface. Habit: stay professionally warm, prepare as fully as for a formal round.

Whatever the format, the underlying preparation is shared. Knowing your own examples cold, structuring them in STAR, and having said them out loud beforehand carries across every interview type on this page. The format changes the room; it rarely changes the questions as much as it first appears.

The most reliable way to get ready for a mix of formats is to rehearse against the actual role rather than a generic list. That is what AI interview coaching is built for: it generates a mock interview from the job description and your CV, asks role-specific behavioural, technical and company-fit questions, flags weak answers, and tracks improvement across sessions, so you can practise the competency and presentation parts of an assessment centre before the day itself. One honest limitation: interview practice currently runs in English, though the answer structures here transfer across languages.

Frequently Asked Questions

The basics

What is a job interview?

A job interview is a structured conversation in which an employer gathers evidence on whether you can do the role, would do it well there, and fit the team. It is not a test you pass or fail on the spot but a sampling exercise, and the format chosen tells you what the employer most wants to measure. A phone screen samples basic fit, a competency interview samples behaviour, and an assessment centre samples how you work.

Group and university formats

What is a group job interview?

A group job interview assesses several candidates at once, usually through a discussion or a shared task, while assessors watch how each person contributes. The employer is measuring collaboration, listening and influence rather than the right answer. Contribute clearly, build on what others say, and never win the task by talking over the room, because dominating reads as a red flag.

How do you prepare for a group interview?

Prepare to be a strong contributor rather than the loudest voice. Plan to speak early so you are visibly engaged, reference other people's points by name, and watch the time on any task. Assessors score how you help the group succeed, so bringing a quiet candidate into the conversation often scores higher than pushing your own idea through.

How do you prepare for a university interview?

Treat a university interview as a subject conversation rather than a job pitch. Re-read your personal statement and be ready to expand any claim in it, read around your chosen subject so you can discuss something current, and prepare to think aloud rather than recite. Interviewers want to see how you reason, so a thoughtful unfinished answer beats a polished but shallow one.

Difficulty

Which type of interview is hardest to prepare for?

Most people find the assessment centre hardest, because it runs several formats across a day and tests stamina alongside skill. The fix is to prepare each format separately rather than treating the day as one event, then rehearse switching between them. Mock interviews built from the role help most here, since they let you practise the competency and presentation parts out loud before the day itself.

Conclusion: read the format, then prepare the room

The types of job interview look intimidating as a list and shrink the moment you ask what each one is testing. Match the format to its purpose, prepare your examples in STAR, and rehearse the harder formats out loud before the day. When the invitations start arriving, our guide to interview questions and answers covers exactly what to say once you are in the room.
