The interview is very straight-forward. Expect a case study for about 45 minutes plus a detailed walkthrough of your previous work / project experience. Hint -- this is an accounting firm, and they'll expect you to work your way through a balance sheet in the case study regardless of service area.Not sure what level you're applying at, but if at exec/manager level there will be an assessment day afterwards, covering a group exercise, case study, presentation, written exercise, and partner interview.Good luck.
