RSM interview questions

The dept. chair at my University was collecting resumes from accounting students close to graduating, I gave mine and it was sent to HR at RSM. Was contacted, asked to come to interview. Was surprised to be in a group setting (which made it feel competitive). Briefed us about the company and the position for 15 mins and sent us off to get interviewed by a manager/partner. Was more like a conversation than scripted questions. I felt like it was one of the more easier interviews I've done so far in my career. Then they treated us to lunch to answer more questions with a group of young staff. I'd like to note that this interview was for a position that was to start one year after the interview.
