As I recall it was very straight forward. I interviewed with both the regional medical director and the lead veterinarian at the hospital location that I was hoping to work at. They looked at my resume and then asked pretty standard interview questions - nothing I would have considered a curve ball. The two people that interviewed me were friendly and I was pretty comfortable.

There are 2 rounds, one with recruiter and the other with the area chief of staff. they are pretty easy taking, and the interview went really well. its not very difficult.
