Everything is documented in the FOM (Flight Ops Manual) so there is no super secret club, other than the names of those who are on the committees (which isn't in the FOM). The PINS guys are pilot recruiters with 5+ years experience as recruiters, and they are the ones who decide who gets an interview. The PHC are the Chief Pilot, Director Flight Training, Director Flight Standards and Director Talent Acquisition. I am told they meet every 2 weeks to review files of those candidates whose backgrounds have been completed. Since TBNT emails went out this week, they must have just met, so the next one would be in 2 weeks (if the pattern holds true)
