It sounds like theres a lot going for Piedmont. I am looking hard at applying with them. Any recommendations on material to study etc., things I can do to help prepare prior to the interview?

My background: USN pilot with 2300hrs in T-6/T-34/T-44 and P-3s. I'm currently on a non-flying tour and will have been for 3 years when April 1st rolls around (when I get out). I've seen on the Piedmont profile that they're preferring individuals to be in an active flying position, but is that a deal breaker in order to get an interview?
