I attended an accounting job fair at my university and was able to get an interview. You may also attend a pre-interview dinner at a local restaurant the night before interviews. The interview is pretty straight-forward. It was a behavioral interview (tell me about a time when...). Following the interview process it takes quite a while to hear back. Most firms try to notify you within 2-3 weeks. I think GP called me about 2.5 months after the interview.

GP was at the LSU Career Expo, I was able to get an interview with them the following day after dropping my resume with them and applying online. The time slots were 45 minutes but my interview only lasted 15 minutes. Hoping that's not a sign. My interviewer was very friendly and nice. Haven't heard back yet, disregard the question if I got the offer.
