Nightwatch and fumes, I never applied, just going of 2nd hand info from friends who've gone thru it.
If you're a Brit, Ausie, or from NZ, I'm told it's a gentleman's interview with "basic ATPL" and company knowledge... on the other hand, if you're American or FAA licensed as Mesa is, then it's a whole different ball game.
So either, a) 3 of my friends (one of whom did get hired) were lying, or they've changed it since last year?
Good luck Mesa.
