The first call was from HR to setup an interview directly with the hiring manager. The actual interview call was fairly laid back as they listened to experience and previous duties. There was no standard template they followed (what are your strengths, weaknesses, etc). It was all to the point of the particular position. The in person interview was casual as well with questions about my past experience but with a little more detail. After that I was given a tour of the area I would be working.
