Online application asking for pilot credentials, flight times, experience, define integrity. Phone interview with HR in Virginia, very basic, verifying application info. I interviewed in California, very simple. Again verifying application info, why do you want the job, what makes a good pilot, define integrity. After the actual interview, you are tested on instrument skills with a flight simulator type training device. They give you the route, charts, plates, and what to expect. You get your clearance, take off, fly the route, shoot the approach to the missed. Basically they are looking for solid procedures, not if you can fly a perfect ILS.
