They called me in after a phone interview with HR. Had to take a test before actual interview. Actual face to face interview consisted of two hours. I interviewed with the head of the AP department and then interviewed with direct manager that I would be working under. Lastly I interviewed with a panel of the rest of the supervisors. Not intimidating as I describe it because everyone is very nice, direct, and professional. Although it’s nerve wrecking, it was a great experience. Goo practice. If you get thru an interview like that, you can get thru anything.
