1.5 hours total. First, an overview of the team (other interviewees there). Then two 30-min interviews. Both of my interviews were very laid back and friendly. The questions centered around work experience and how you problem solve. The only "case" like question was very vague and designed to see how you approach a problem.

It seemed like I was doing more of the interviewing than being interviewed, the impression was that this was just something they'd have to do.
