Call for interview vs. mailed app.
I dunno how they work the paperwork mailing vs. immediate call for an interview thing. I faxed a resume on a Fri, got the app in the mail the next Sat, which I just mailed off on the following Mon.
Would've been a lot nicer to just get a interview without signing my name to consent four hundred times, but if I get the call I certainly won't complain.
My guess is if you've got around 1800 or some valuable experience, they just sign you up for the interview, otherwise they make you fill out the paperwork first for a closer look.
The future is a little uncertain anyway, what with US Airways on the ropes and all, but how sweet would it be to fly something like the Do328?
