A question of leadership
Following the above posts I can't help feeling that the Jet2 management have been suckerd into letting the HR department have the upper hand in pilot recruitment, no doubt the reason for this is that they are very aware of the politically correct HR need for an absolute measure of a candidate that is not based on the human perception.
This attitude from the HR department is reinforced by the fear that Jet2 may find its self in court on some sort of discrimination case, using the compass tests gives them a way of fending off this sort of accusation.
The problem is that this system is deeply flawed and has failed to get the pilots into the company, it is clear that it is now time for the management pilots to take back the upper hand in the recruitment of pilots.
HR people are good servants but bad masters !
