Got an initial interview from the company due to a friend's referral. The initial interview consisted of a phone screening. I also got an on-campus interview afterward, which was unrelated to the phone interview. The on-campus interview consisted of a first-round interview on a Monday. They then called on Monday night to inform me that I had made the second round, which would take place in the form of three interviews on campus over the next two days. All the interviews were very technical, with one or two behavioral/resume questions thrown in. The interviewers themselves were pretty laid-back and fairly helpful, they weren't trying to confuse me or make life difficult. They told me that they would get back to me by the end of the week, but took until the middle of the next week to get back to me. I wasn't offered the position, even though I thought I did reasonably well on the interviews.
