I interviewed last week.
The quiz - airfield information, thunderstorms, windshear, icing. There is evidently a bunch of different tests, but that's what mine had.
HR - standard stuff, pretty much how you would fit into the CS culture
CP (Tech) - AIM info, reading app/dep plates, basic aircraft performance (It's hot out, the jet is going to be heavy, what can I do to get the min climb gradient?), Part 135 rules (alternate requirements, alt wx requirements). The AIM information focused on stuff we don't see in the 121 world..non-tower, VFR ops, etc.
Hit up the CS folks here - lots of questions centered on if I knew why CS was different, what the culture was (find a way to say "YES" for the customer), what the expectations of working there were.
I dorked up the first 2 tech questions and pretty much killed the interview with the CP there, so I didn't get an offer. They're hiring 20 or so into a pool to have available when/if they start expanding again - which they won't do until they have enough new customers...no guess on when that would be, but it sounds like business is down a little.
Great company overall though - disappointed I ****ed it away. Good Luck!
