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.
