I applied online. The process took 2 months. I interviewed at General Atomics (Palmdale, CA) in Jan 2016
Interview
Got a phone call to set up a phone interview. Phone interview was very basic as overall knowledge of mechanics, engines, and airframes. After that phone interview they paid mileage to have me drive for a face to face and walk around the facility. Again, very basic knowledge (at least for me) about engines, airframes, and overall mechanics.
Interview questions [1]
Question 1
They asked me to read a schematic of an engine and point out certain parts.
Also, had me point at different control surfaces on an MQ-1.
