Had a relatively new reserve FO the other day that went through ATP Flight School. I shuddered when I heard his accounting of the experience. Among other things, he said he was sent to RAH shortly after his Commercial license was finished. Literally they flew him up to Indy and brain washed him. He said he felt like he needed to take a shower afterwards.
He said in his time there, he was pushed into interviews at several airlines he had no interest in. He didn't even realize they were voluntary. People just called him and/or emailed him and said "your going here for an interview on this day". He said it often interrupted his training.
