Assessment centres are the final filter before an offer — usually a half-day or full day combining several exercises. It sounds intimidating, but every part of it is preparable.
What's typically included
- Group exercise — a case or discussion task done with 4–8 other candidates, watched by assessors
- Case study / written exercise — analysing a business problem and presenting a recommendation
- Individual interview(s) — competency-based, sometimes technical depending on the role
- Presentation — often prepared in the room with limited time, then delivered to assessors
The group exercise: what assessors are actually watching for
Not who talks the most — who contributes well and helps the group reach a decision. Bringing in quieter members, building on others' points, and keeping the group on track for time all score better than dominating the conversation. Being visibly collaborative under mild pressure is the entire point of the exercise.
Case studies: structure beats cleverness
Assessors mark structure and reasoning more than a single "correct" answer. A clearly reasoned, average recommendation typically scores better than a brilliant idea explained chaotically. Lead with your recommendation, then walk through the reasoning — don't save the conclusion for the end.
Presentations: use the prep time fully
Write a simple structure before worrying about polish: 3 key points, one line of reasoning each, one clear recommendation. Time yourself in practice — running out of time mid-point looks worse than a slightly shorter, complete answer.
The most under-rated skill
How you behave when you're not being formally assessed — lunch, breaks, casual chat with other candidates. Assessors and current employees often informally note impressions from these moments too. Treat the whole day as being observed, politely and consistently.
