One of the guys in my interview group had just come from a week at ATP in Jacksonville and their CRJ course. He said that the course did little to prepare him, as there was virtually no hand flying on raw data during their training.
We had a couple in our interview that had a prep course too and they also said it was mostly about the automation that then didn't help them in the sim eval. You have to get the job before it matters if you can fly the autopilot, maybe ATP needs to figure that out.
