Assessment Centres and What to Expect

What is an assessment centre?

The assessment centre is usually the final stage of the application process for graduate schemes and apprenticeships. It is a half-day or full-day event where you are assessed alongside other candidates.

The term "centre" is slightly misleading. It simply means a gathering of candidates and assessors, usually at the employer's offices or conducted virtually via video call.

Employers use this format because it simulates the real working environment better than a standalone interview. They want to see how you process information, how you work in a team, and how you handle time pressure. For where the assessment centre fits in the wider process, see our applications and assessments guide.

A typical day

Every employer runs its own format, but a full-day assessment centre often looks something like this:

Half-day and virtual assessment centres usually cut this down to two or three exercises. Some employers also ask you to repeat a short version of your online tests under supervision, to confirm the results were your own.

How you are scored

Assessment centres are designed to be as fair as possible. Each exercise is scored by trained assessors against a set of criteria, usually the same skills or values listed in the job description or on the employer's careers site. Different assessors often watch different exercises, and they compare notes at the end of the day in a meeting sometimes called a "wash-up".

Two things follow from this:

• One weak exercise rarely sinks you. Decisions are based on your performance across the whole day, so if one exercise goes badly, reset and focus on the next.
• Know the criteria. Re-read the job description and the employer's values before the day. They tell you what the assessors are looking for.

The group exercise

This is the most common feature of an assessment centre. You will be placed in a group of four to six candidates and given a brief to discuss or a problem to solve within a strict time limit (usually 30 to 45 minutes).

Common scenarios include ranking a list of priorities, deciding which fictional projects to fund, or managing a crisis.

How to succeed

• Do not dominate. This is not a competition to speak the most. Aggressively shutting down other people's ideas will count heavily against you.
• Facilitate. Assessors love candidates who bring quiet people into the conversation ("What do you think about this, Sarah?") and those who keep track of the time.
• Build on ideas. Say, "I agree with Tom's point about the budget, and we could take that further by..." rather than just pushing your own agenda.
• Be the timekeeper. Volunteer to watch the clock and give five-minute warnings. It shows leadership without requiring you to dominate the content.

Case studies and written tasks

You will be given a pack of information—such as fictional emails, financial charts, and company reports—and asked to analyse it.

You might have to write a summary report, draft an email to a client recommending a course of action, or complete an "e-tray" exercise (where you must prioritise and respond to a rapidly filling simulated inbox).

How to succeed

• Scan first. Do not try to read every single word. Scan the documents to understand the overall picture before diving into the details.
• Watch the time. These tasks are deliberately designed to contain too much information for the time allowed. Prioritise the most critical data.
• Structure your answer. If writing a report, use clear headings, bullet points, and an executive summary.

Presentations

You may be asked to give a short presentation to an assessor. Sometimes you will be given the topic a few days in advance; other times, you must prepare it on the day based on the case study you just completed.

How to succeed

• Keep it simple. Do not overload your slides or your speech with data. Focus on three main points.
• Structure. Tell them what you are going to tell them, tell them, and then tell them what you told them.
• Prepare for questions. The assessor will challenge your conclusions. Do not take it personally; they want to see how you defend your ideas and whether you can remain calm under pressure.

The golden rule: You are always being assessed

The formal exercises are what get scored, but they are only part of the day. Staff notice how you behave during coffee breaks, at lunch, and while you are waiting in reception, and at some employers that feedback is passed on to the assessors.

If you give a brilliant presentation but are rude to the receptionist, or sit in silence looking bored during a talk from a current graduate, it can undo a lot of good work.

Be polite, show genuine interest in the company, and chat with the other candidates. Remember that the other candidates are not your enemies. If you all perform exceptionally well in a group exercise, the firm can hire all of you.

Virtual assessment centres

Many employers now run assessment centres entirely online. The exercises are the same, but the medium requires different preparation.

• Check your tech. Ensure your Wi-Fi is stable, your camera works, and your microphone is clear. Join the link five minutes early. Our video interviews guide covers lighting and camera setup in detail.
• Eye contact. Look at the camera lens when speaking, especially during presentations.
• Group dynamics. It is harder to read body language on a video call. Be extra careful not to interrupt people during the virtual group exercise. Use the "raise hand" feature if appropriate, or wait for a clear pause.

FAQ

• What should I wear?↓

  What should I wear?

  Follow the dress code in your invitation. Many employers now ask for smart casual rather than suits. If it does not say, ask the recruitment team, or default to business smart (smart trousers or a skirt with a shirt or blouse, and a jacket you can take off). It is better to be slightly overdressed than underdressed.

• How should I prepare?↓

  How should I prepare?

  Re-read your application and anything you said in your video interview, research the company's recent news and values, and have a few STAR examples ready for the interview. Practise presenting to a friend against a timer. Check the logistics too: the address, travel time, what ID to bring, and whether the employer covers travel costs.

• Can I ask for adjustments?↓

  Can I ask for adjustments?

  Yes. If you have a disability or condition that affects how you take part, such as needing extra time for written exercises or a quiet space between sessions, tell the recruitment team when you accept the invitation. Employers must make reasonable adjustments for disabled candidates.

• What happens if someone in my group exercise won't stop talking?↓

  What happens if someone in my group exercise won't stop talking?

  Do not get into an argument. Wait for them to take a breath and interject politely: "That's a really interesting point. I'd love to hear what the rest of the group thinks about..." This shows the assessors that you can handle difficult personalities professionally.

• When will I hear back?↓

  When will I hear back?

  Usually within one to two weeks. Assessment centres are expensive and time-consuming for employers, so they tend to make decisions quickly once the event is over. If you have not heard anything after two weeks, it is fine to send a polite email to the recruitment team. If you are unsuccessful, ask for feedback; many large employers will give it.

Next steps

If your assessment centre includes a final interview, you will need to prepare for different interview styles.
