Got an interview on campus through the business school. First interview was very generic, around 30 mins with current senior rep. Very easy, wanted to see what knowledge I had on the company already and ask general resume questions.
Second interview was the following week with a group of 3 senior reps/area managers of some sort. Lasted a little over an hour, all behavioral and "what would do you if" questions. Two of the guys were friendly and welcoming, third guy played bad cop and criticized responses and frequently demanded different ones. Also criticized my personality some, which was hard at times.
Good interview experience, good way to see if candidates can stand their ground around doctors in the real position. Showed me I wasn't cut out for that type of work.
