Five interviews including one with the hiring manager, a second with the same hiring manager and another area manager (after which I was given a book on Pharmacology, told to study it, and asked to come back in to take a test during my third interview); the fourth interview was a ride along with reps on the team with which I'd be working, and the fifth and final interview was with a Regional Manager. Everyone I met with was friendly and accommodating while still remaining professional.
