Phone conversation with Human Resources personnel. This was the first stage. I was not contacted for the second stage, which would have included multiple Department specific personnel and may have led to a third interview with upper management. I was told I might receive technical questions related to my area.

Phone interview in the start with HR. Team interview after that with 2 rounds of 4 interviews each. Past experiences reviewed. Technical concepts reviewed. Half a day interview. Info shared same week with offer.
