Back when I interviewed it was a 3-hour written test with a short essay on mach tuck and the theory of aerodynamics that cause dutch roll.

Then it was off to the sim, where we flew some V1 cuts in the SR-71 sim they have and a few approaches and missed approaches (single engine, of course) to a (simulated) carrier landing, at night, with rough seas.

After that, if you passed, they sent you off to survival training in the desert. Like NASA used to do.

Simple stuff really.

I don't know what they do anymore. But I've heard from a knowledgeable source that there is a written test with ATP questions and a simulator check that tests IFR skills.

And don't tell them that you want the job so bad that you'll work for free. They had one recently who did that. Not sure he made it to the survival training part....
