Initially applied through the career center at my school and received an in-person, on campus interview with a non-HR employee. Interview was only 15 minutes and was basically just a personality fit. I was told I would be contacted by the recruiter at the conclusion of the interview, which meant I had moved to the next round. Then I talked over the phone with the recruiter about a week later and this was another personality fit along with a basic phone interview. After a month or so I was notified that I had been chosen to participate in a final-round interview in their Chicago office. The interview consisted of a 5 minute "interactive resume" presentation, and 5 45-minute interviews. About a month later I was notified they were not going to make me an offer.

Applied through university recruiting. A recruiter emailed me a couple of weeks later asking if I was still interested in working for them, and 1 week after that we scheduled a phone interview. It was a conference call with 4 other people listening, it lasted about 20 minutes. It was a negative experience not because I didnt get an offer, but because they were not friendly and did not make me feel welcomed in the phone call, it was very dry.
