Pilots (loose term) apply for entry level jobs in the industry.
A great many have an attitude of "I know it and I just need to get into the airline........dadadadadada"
On pre employment check flights they struggle with the absolute basics.
Put simply, training prior to employment is schetchy at best, down right pointless at worst.
It may be training and /or the person being trained but the outcome mostly is very average.
As a side point, if it is the person, I believe it is the instructor and the flying organisation that is responsible for adjusting the person and teaching the realities of the industry and of airmanship.
Operators then have a degraded pool to choose from. Operators carry the responsibility to then train the pilots, (note train and not retrain).
Who's at fault?
Flying schools?
Operators?
The person?
My guess is the monitoring and action to the syllabus.
All in all, a right pain in the arse at the end of the day.
