I just applied to SKW and wanted to get a jump on studying for the ATP written using Sheppard Air. The operator talked me into buying the interview prep, but the software says not to use for any regional other than "for Mesa, Go, Piedmont, Trans States, Commutair , Republic, Spirit, Miami Air, ExpressJet & Air Wisconsin interview tests."

Is this a total waste of time for interviewing at SkyWest?

Thanks!
