aviationinterviews.com and willflyforfood.cc, plus talking with a friend of mine who just went through the interview, was all it took. They are looking for teachable, not a Shuttle commander!
The Sim is VERY pitch sensitive. If you have never flown a FRASCA, it probably won't be your best effort, but again, they are looking for good skills, not a FRASCA expert. Make sure you are hand flying as much as possible (safely, of course) and keeping your scan up.
Memorize the AE mission/vision statement, specifically the "safest, most reliable, most successful" part, with an emphasis on "safest".
Good luck!
