First there was a screening process through USA Jobs. Be sure to use the write lingo and jargon to match your experience to the duties listed in the job opening. Once you clear that hurdle, there is a sit-down with your supervisor and the Executive Officer. The interview was a substantive conversation about skills, responsibilities, reasoning, and some small talk about hometown, etc. There is of course also a component where you go through background checks to attain a security clearance.
