Grant Thornton Assessment Centre 2027: Exercises & Tips
The Grant Thornton assessment centre is the final major hurdle of the 2027 process — a half or full day of exercises where assessors watch how you actually work, not just how you interview. Typical exercises include a group discussion, the written case study, and a final partner interview. Candidates who sailed through the video interview fail here every year, usually for the same reason: they prepared for questions, not for exercises.
Grant Thornton Assessment Centre Exercises
Expect some combination of the following:
- Group exercise: A team task — prioritising options, solving a business problem, or reaching a consensus. Assessors score collaboration, communication, and influence, not who talks most.
- Written case study: Around 22 minutes to analyse briefing materials and write a short report with recommendations (see our dedicated guide).
- Partner/director interview: Motivation, commercial awareness, and your strengths in more depth. "Why Grant Thornton?" returns here — bring a longer, richer version.
- Presentation (some service lines): Presenting your case study findings or a prepared topic.
Tips for Each Exercise
Group exercise: Contribute early to establish presence, build on others' points ("to add to what X said..."), and manage time for the group. Never dominate, never disappear. The assessor is scoring teamwork against the Collaboration value — the loudest candidate often scores worst.
Written case study: Recommendation first, structure with headings, watch the clock. Practise timed beforehand.
Partner interview: This is a conversation, not an interrogation. Prepare two thoughtful questions for the partner — about their client work, the team, or market trends. Asking nothing signals low interest.
The Assessment Centre Mindset
The Grant Thornton assessment centre tests consistency. Your strengths stories, motivation answers, and values examples must align with what you submitted earlier — assessors compare. The biggest risk is not any single exercise but the cumulative impression: candidates who performed "a version of themselves" at each stage eventually contradict that version under a full day of observation.
Prepare for the day as a whole, not as isolated tasks. Sleep properly, arrive early, and treat every interaction — including with other candidates — as observed, because it is. One bad exercise rarely sinks you; a pattern of inconsistency or disengagement does. This is the last gate before an offer — do not let a year's effort end on an unprepared afternoon.
