Deloitte Audit Assistant interview questions

I had two rounds of interviews. First round was through my university's on campus recruiting office. 30min with a Partner; interview was behavioral. Heard back four days later, got second round interview. This round was in-house, 8:30am-2pm. It included a short breakfast, followed by three 30min interviews with two Partners and one Manager. Afterwards a lunch with young professionals. Heard back two weeks later with the offer.

I asked my professor about the Deloitte office in Fresno, CA. He called someone at their office on Tuesday morning. Within 30 minutes they emailed me asking me to meet them for coffee that Saturday. I was offered the job at that interview. I don't think this is a normal experience, I have a GPA of 3.95 and they were very impressed. Also, a professor referral goes a long way, and he was an amazing professor.
