Congratulations — you’ve aced the application, and you’re down to the final stage: the assessment centre. These days combine practical exercises and interviews, testing everything at once, which is exactly why they feel so intimidating.
This guide isn’t about the mechanics of each exercise (see our full breakdown of what assessment centres actually test for that) — it’s about walking in with the right mindset, because that’s what most candidates underprepare for.
Know what they are looking for
Like any interview, you want to know the company’s competencies inside and out — what they value, how they want to be seen, and what the bigger picture is. Because of how the day is structured, you won’t just talk about these values; you’ll have to demonstrate them practically through role play and group tasks. The company you’re interviewing with will most likely send you examples of their tests — or see our full breakdown of what each assessment centre exercise actually tests for the practical side of preparation. If they don’t send examples, get in touch with your university careers service and ask for a mock interview with standard tests to practise at home.
Brush Up on Your Numerical Skills
If numbers haven’t been part of your degree, it’s worth recapping percentages, graph interpretation and quick fractions — even non-technical assessment days often include a numerical reasoning element. Use any stats given in your tasks effectively; a few evenings revisiting GCSE-level maths (BBC Bitesize’s app works well for quick practice) pays off far more than it sounds like it should.
Be a Team Player, Not the Loudest Voice
Employers watch how you interact with others as closely as what you say. It’s tempting to fight for the “leader” role in a group exercise, but remember everyone else has the same instinct — eight people all trying to lead just becomes noise. Be professional, use people’s names, make eye contact, and bring quieter people into the conversation rather than talking over them. It genuinely doesn’t matter if your specific idea isn’t the one the group runs with — what’s being scored is how engaged you are and how well you handle other people’s input.
Look After Your Mind and Body
Almost everyone walks away from an assessment centre feeling like they underperformed on at least one exercise — that’s normal, not a sign you’ve failed. Assessment centres are deliberately designed to create a pressurised environment, so resilience matters more than any single strong answer. Sleep properly the night before, eat a real breakfast, and bring lunch if it’s a full-day event — low blood sugar on hour six of a long day is the last thing you need. Treat the strangeness of the day (unfamiliar office, everyone dressed to impress) as something to get curious about rather than dread.
The whole experience can feel extremely strange; you’re in an unfamiliar environment, and everyone will most likely be suited and booted to impress. Embrace the surrealness of the situation, try to enjoy it and give yourself the best possible chance of success by following this guide and feeling as prepared as you possibly can.
If nothing else; breath, smile and fake it til you make it.
