KPMG Graduate Trainee interview questions

Did some online tests, not very difficult. They called me for a 3h30m session with a group dynamic, more tests and an interview. For the group dynamic they gave us a case and 10 min to think about it for ourselves. Then we had to discuss it for 40 minutes or something. Everyone tries to show off and no one seems natural. A lot of people try to take the lead. I recommend letting them. When they say stuff that is wrong just correct them and argue for your position. If you are right and everyone agrees with you congratz you are now the boss. Always think you are the boss. Be very very confident and don't be afraid to speak.
