Centaurus,
The problem with civvie training up to the airline intake is that nobody really fails and if they do, they just throw more money at the problem until it supposedly goes away.
Airlines all over the world hve the odd crew member that takes " a little longer to get through". The problem is that these problems that arise never really go away. They turn into expensive training events following busted checkrides or enforcement action from the certifying body.
"Have you driven a Ford lately?" If you have you'll know that they haven't learned a thing. High consumption, poor finish and recalls that centre around catching on fire. Some of these things can be fixed: others you just have to live with...or get another car.
Pilot recruitment is pretty much the same way.
