Initial phone screen by HR, followed by phone screen by hiring manager and then an in-person interview, The phone screens were pretty generic and just went into your background and experience. In-person interview with engineers was great. But HR lady was a snob with a "holier than thou" attitude. Seemed to convey the impression that people were treated like work machines. If you do not perform, you are out the door the next day. While I had no issues with that, she herself did not seem smart enough to adopt that attitude.

I was contacted via my LinkedIn account - the hiring manager and I had a common friend of mine. After I accepted the invitation to chat we had a long phone call. About two weeks later I went for a whole day of interviews and spoke with six people. On the following week had another two interviews with the higher management. At that point the hiring manager mentioned there was some reorg going and they'll have to hold the process for some time. Overall the whole process was fair and everyone was friendly throughout all interviews.
