I had a phone screening, then two in-person interviews with several people. The whole process took over a month I believe, but it was well worth it. They split up the interviews so I wasn't speaking to more than two people at a time, which I appreciated. I find panel interviews to be way more stressful than necessary. My first set of interviews felt a bit rushed, probably because the people interviewing me were conscious of going over into someone else's time. However, the second set was more relaxed and went over the time allotted because they wanted to provide as much information about the position as possible.
