Smaller firm = more responsibility. Show you take ownership.

Avoid
Common mistakes at Grant Thornton assessment centres
Trying to dominate the group exercise. Grant Thornton explicitly rewards collaboration. Build on others' points and summarise for the group.
Not knowing Grant Thornton's values. They assess against their values framework — know them and demonstrate them naturally.
Being too generic in the partner interview. Reference specific service lines, recent work, or firm initiatives.
Ignoring other candidates. The social elements (lunch, breaks) are part of the assessment. Be friendly and engaged throughout.
Under-preparing for the case study or written exercise. Practise structuring analysis under time pressure.
Not having questions prepared. "No questions" signals lack of genuine interest.
