It was an on-campus recruiting interview. There were two greeters waiting in the lobby and I talked with them for about 10 mins before it was time for me to meet the interviewer. They were both very friendly, had been at the firm for 1 year, and went to the school at which I was participating in the on-campus recruit. But make sure you have questions to ask them. (generally stuff about themselves, when did they start, have they taken any parts of the CPA, how do they like working there etc). The interview itself was with a partner. He was very friendly and outgoing. He asked questions like, how did I obtain the internships on my resume, why do you like accounting, what is my 5 year plan, describe to me what you did at each of your internships. Thats about 15-20 mins. Then the next 10-15 is questions that you need to ask the interviewer. Make sure these are conversational, and not just firing questions at your interviewer. Act like you are interested in the response.
