The piedmont interview was really not that bad. They take you all in at 7:45 and give you a presentation before they give you the written test. Know 121 regs cold. There will be about 10-15 qs on Jepp charts/plates which aren't too bad. Browse over the aim, it seemed like they try to find a lot of obscure information to turn into a question. After that, if you pass, you can move on, if you don't, they ask you to leave. A little nerve racking but the sim ride wasn't bad. Track to and from a station, how would you enter a hold from here, okay, im gonna put you here to intercept the ils to whatever runway. The hr interview impressed me because it is with the chief pilot so very personable, very short, and very straight to the point. If you pass the written test, the rest is a pretty good experience and most the guys i interviewed with were pretty exceptional guys. hope this helps!
