I don't necessarily think that's true. Why would they bring you out there for an interview and waste their time, money, and resources on you if they had every intention of just sending you home? I think they are just expecting too much out of the sim evaluation. If you don't mess up the procedures and don't do anything stupid, that should indicate that you are trainable. I don't think they should be holding the applicants to practically ATP standards at that stage of the game, especially with so many people coming in from backgrounds of mostly CFIing in seminoles and the like. But that's just my opinion.
