If they like your resume, the reply is very timely. the gouges on aviationinterviews.com are dead on, the written is the hardest part, lost 1 guy out of about 10 when i interviewed. Then I heard of another group loosing 5. But if you study and prepare it is simple, I was done in about 15 minutes, just because I spent my 2 weeks preparing for it. You could get the level D sim, or the PACTD, depends on availability. The ride is pretty simple, they just want to see of you can fly instruments, because that is where they have been loosing some people in sim training, with all the low times and such.

good Luck!
