I can hear it now, "OK Boomer", but here is the real deal about airline training. You need to know your aircraft systems. You need to know your aircrafts limitations. You need to know how to properly fly a V1 and V2 engine failure. You need to know how to execute an emergency descent, You need to know how to fly a non-precision and precision approach. You must learn to function as a crew. Nothing has changed in 50+ years. If you can do these things competently you will pass and thrive at an airline. If you have a good attitude and need a little help you will most likely get it. If you are unable to master these skills in todays environment you will most likely be let go. AQP or Old School you still need to be able to do these things and it was, has been and hopefully always will be up to the individual to prepare properly. I've done both types of training plus some overseas that doesn't fit either category and it is all about individual preparation. Short of poor instruction/checking, which is thankfully rare, most pilots do fine regardless of the program.
