RSM Audit Associate interview questions

Met the company at a career fair at my university and spoke with multiple people. I was invited to an on-campus interview which was a 1:1 with a partner. We basically just had a conversation. He asked about my interests outside of school and got talking about those subjects for 45 minutes (it was only supposed to be 30 mins). 3 weeks later, I got an invitation to an office visit interview. The night before there was a cocktail social at a nice hotel where I got to meet a lot of employees and other students interviewing as well. The office visit consisted of 3 30 minute interviews, 2 of them with partners, 1 with a manager. They didn't ask me any of the typical interview behavioral questions, instead we just had a casual conversation. It was great because I had meet 2 of them previously at the socials/career fair so it was a comfortable and relaxed conversation. After the interviews, they took all of the interviewees to lunch where we got to chat some more.

I went to the campus career fair then signed up for campus interview. Within one week was notified that my request for interview has been accepted. The campus interview was 1:1, with questions like "your work experience/ behavior question". 2 weeks later received an email invitation for Office Visit. The Office Visit consisted 3 of 1:1 /30mins each interviews. Lots of behavior questions! Overall, good experience except the first person that interviewed me was a bit of unprofessional(in my opinion) because as I was instructed into this person's office, he/she greeted me but then turned around working on his/her computer said was writing an email to a client. I just sat there looked at this person for 2 to 3 minutes.
