KPMG Internal Auditor interview questions

Applied through my university and had one on campus interview. About a week and a half later, I was invited to visit a local office for about three hours worth of interviews. Candidates had lunch with some newer associates, then had three interviews. My flight was delayed coming in and I only had the opportunity to do two interviews. Interviewers were senior management within the firm, and were very nice.
