Initially contacted by HR. I think I got points for my cover letter, which was rather frank and slightly self-indulgent. Take chances. It'll get you noticed The first interview was with my potential immediate supervisor. Interview was a personality test mostly and also was checking to see if I understood the requirements of the position. The test focused mainly on conflict resolution. At the end there was a skills test. Second interview happened about a week later. This one was with higher management for the division I would be working for. Again it was a personality driven interview, mainly to gauge how I would handle certain situations. They really seemed to value the ability to be team-oriented and interface with other well. Once I could relate that I had the ability to empathize, make tough decisions, and present a clear logic for making the decisions, the interviews progressed naturally and fluidly. Again, a lot of the interview process also depends on being able to show your interviewers that you understand your role and can handle the particular issues you face in that role.
