Surviving the assessment centre
Group exercises, presentations, in tray tasks and interviews, often in a single day. Here is what assessors are really watching for.
For many UK graduate schemes, the assessment centre is the final hurdle. It can last half a day or a full day, in person or online, and usually combines several exercises. It is tiring by design. Assessors want to see how you work, not just how you interview.
What to expect
Every employer runs its own format, but most assessment centres draw on a familiar set of exercises:
- Group exercise. A small team discusses a problem and reaches a recommendation, while assessors observe.
- Presentation. You prepare a short talk, sometimes in advance and sometimes on the day with limited preparation time.
- Case study or in tray exercise. You work through documents, emails or data and make decisions under time pressure.
- Written exercise. You draft a short report or email based on information provided.
- Interview. Often competency based, sometimes with a senior manager.
The employer should tell you which exercises to expect. If they do not, it is perfectly reasonable to ask.
The group exercise is not a competition
The most common mistake is treating the group task as a contest to be the loudest voice. Assessors are usually watching for collaboration, not domination. They want to see you:
- Contribute ideas that move the discussion forward.
- Listen and build on what others say.
- Bring quieter people in. Asking “what do you think?” to someone who has not spoken is noticed.
- Keep the group on track, for example by watching the time or summarising progress.
You can be quietly excellent in a group exercise. You cannot be rude and still do well.
Presentations: clarity beats polish
A good assessment centre presentation has a clear structure: what you recommend, why, and what happens next. Keep slides simple, stay within your time, and prepare for questions. If you do not know an answer, saying so calmly and explaining how you would find out is better than bluffing.
Under time pressure, prioritise visibly
In case studies and in tray exercises, there is often more to do than time allows. That is deliberate. Assessors want to see how you prioritise. Briefly note why you dealt with some items first. A clear rationale for leaving something unfinished is better than rushing everything badly.
Remember you are always being assessed
Lunch, breaks, and conversations with current employees may not be formally scored, but impressions still form. Be friendly and professional throughout.
Look after yourself
Sleep well, eat properly, and plan your journey with time to spare. For online centres, test your connection, camera and microphone the day before. If you have a disability or condition that means you need adjustments, tell the employer in advance. Reasonable adjustments are common and asking for them will not count against you.
Preparation is the difference
Assessment centres reward people who arrive knowing the organisation, the format, and their own best examples. When we prepare candidates, we rehearse each exercise in advance, so the day itself feels familiar rather than daunting.
