I was initially contacted by a recruiter via phone where I was given a (brief) on the spot phone screen interview. I was invited several days later to interview in the KPMG office with a panel of associates. 90% of the questions were behavioral and not very difficult if prepared. The questions are fairly generic and read from a pre-printed list, it is on the candidate to spin the questions into a point of conversation and generate questions of his/her own. I was invited back to the office to meet with several managers/executives in a series of 1:1 interviews, a process that lasted a little over 2 hours. The second round of interviews included more technical questions but still a good deal of behavior questions. It seems as if KPMG is more concerned with the fit of a candidate, just something to keep in mind. Both first and second round interviews were very conversational, not at all as stressful and conservative as I was expecting. The associates do their best to make you feel at ease.
