I think you're missing the point alright, Southend King. As someone in my third airline company, I can safely say all the HR persons so far have been complete tossers, particularly in relation to recruitment. True, they may have a role in areas such as employment law, employee rights (although as in most companies HR are management toadies, they have hardly an unbiased view when it comes to rights of employees) etc etc. However, I think the point being made is that, once you get down to the nitty gritty of interviews, they have no qualifications for rejection of suitable pilots (and of plenty of other types of job) as they frequently do.
This is leaving aside the lunacy of using psychoanalytical tests as initial selection devices. These proving nothing as fooling them is so easy.
