Airline HR people have managed to create a very lucrative cottage industry for themselves with this BS.
It used to be very rare to come across psychometric testing. The old interview with the Chief Pilot, maybe with someone from ‘personnel’ taking notes worked brilliantly for years.
But now we have fallen for the HR mantra, and significantly over complicated the whole recruitment process, whilst also adding in cost.
And it hasn’t achieved anything at all.
Most people who are successful at interview (and maybe a Sim Ride) turn out to be perfectly trainable pilots, are normal people, nice to fly with and get on with the job, and each other. Occasionally, d1kheads get through. It was always the case. BS psychometric tests don’t change this. They have no safety benefit and they do not reduce training risk.
Its just empire building by the old personnel dept.
