My wife just recently had her interview. She said everything went very smoothly and they were very professional. She had a male interviewer, which I have heard helps a lot. The only thing that bothered me was that her interview was scheduled for 7:15, but it took her about 3 hours before she actually was interviewed. They scheduled far too many people for the same time slot. Scheduling could use a lot of work.
