One phone interview with hiring manager, then one phone interview with regional manager, then one phone interview with VP. Three interviews overall that each lasted somewhere around forty-five minutes to one hour.

Very friendly and pleasant actually. Not sure what i was expecting but it was a good interview. Both parties casually explored and discussed expectations and experiences. I was interviewed by three different people - engineers who could provide info on the job but little or no HR type info about company benefits etc. (not a big deal for this type of first meeting anyway)
