Yes you get a pre-offer at the end. After the last interview you still go back to the holding room and wait. They come get you and take your fingerprints and starting faxing out your employment verification forms. You are not given a class date until you clear your background check, review board, etc. Hopefully i'll here back the end of this week about the review board decision. Then its a medical (hearing and drug screen) and they assign you a class.
