I don't have a problem with this. Why shouldn't candidates go through psychological profiling?
It seems extremely unfair to put people through what is a hard process when in fact they cannot ultimately be fully prepared as there is a secret final stage that is out of their hands.
That same could be said of any job interview.
Anyone who puts in the required effort and meets the standards set by NATS at each stage of the application process fully deserves their place on a training course.
If that was the case there would be a
ten year waiting list to start at the college. The psych profiling is used to determine which of those candidates who passed everything else would be most likely to succeed in a high pressure, team working environment, according to criteria stipulated by the employer.
