FEDJOBS.gov posting. Applied through FEDJOBS.gov, informed by phone of top 5 candidacy and emails to schedule 1 day of interviews. 30-45min face to face interview, then acoustic analysis exam. Interview was a panel/group with the CO, XO, Training Officer (point of contact for scheduling, etc.), and senior civilian. Standardized questions for all candidates, round-robin format for asking the questions. Positive atmosphere, enjoyable experience.
