Apply via PERS processes. Need recommendations, minimum flight hours and experience. Also good to have technical degree. Any experience with flight clearances in the fleet help as well. I did not do a face to face interview.
I applied through other source. The process took 3 months. I interviewed at US Navy in Feb 2015
