Already working as Client Service Rep. Interviews with an AS supervisor and the Hub Manager

I met the operations manager at a career fair. He seemed interested in me after reviewing my resume and said they would be in contact. I got a call from the recruiter (whom I also met at the fair) the next day to schedule the interview later that week. I interviewed with two supervisors first. Apparently the ops manager wanted me for an administrative assistant (even though I had work history that made me overqualified for admin asst) and once they spoke to me for 5 minutes they left the room and one came back about 5 minutes later and said that she had no idea why he would want me for the admin position instead of the account specialist position. She went and got two other supervisors (that supervised the AS position) and i interviewed for about 20 minutes with them. Once I got through that interview, I took a math test and a personality test. After, I interviewed with the operations manager. This was all in the same day so the interview process was very quick. It was a pretty formal interview with pretty typical interview questions. I received a call the next day informing me I got the job. I went in the next day for paperwork and negotiation.
