Not to burst anyone's bubble, but they don't always offer training classes based on your interview date or time slot. I know of many guys that were offered classes out of order, usually based on a quick background investigation or military service (or for reasons only they know). For example...My class had guys that interviewed 4 months before me, and there were guys two classes after me that interviewed in the time slots before me. The company also tries to keep a mix of backgrounds in each class...military/regionals/cargo/corporate/OAL.
Good luck, and I hope everyone gets a class ASAP!
