I had a 6 part interview! This was the longest interview process I've ever been a part of. I had a call with a recruiter, in person conversation with the direct supervisor, call with the marketing manager, call with the sales director, then a personality quiz, then a background check. The direct supervisor liked me so much ( I found this out later) that she asked if they could hurry and send me an offer. She called me before hand to let me know she really liked me, just to make sure I wasn't deterred by the long interview process.
