The airplane pilot interview process on top of the standardized government certifications includes:
- On-line application (resume and cover letter)
- On-line Psychometric/Aptitude testing (sometimes this is hands-on, on site for some airlines)
- Video Interview, SKYPE or Telephone interview
- Assessment Day (includes: Technical Questions / Panel Behavioral Interview / Scenario Based Questions / Flight Planning Exercise and sometimes a Clinical Assessment)
- Sim Test
- Referee Check
- Medical Check
The exact details differ by airline and I'm assuming the risk profile of the cargo (ie: passengers or not).
Gosh, not so different from software engineers, is it? Except you also need to do a bunch of bureaucratic certifications on top of that.
