Easy do not have a 'cadet' scheme, they can call it what they want but having candidates pay 100k out of their own parents pockets and mortgaging the house does not make one a 'cadet', also they receive no pay during integrated training.
BA have a cadet scheme, and Lufthansa etc
The other difference is the highly competitive nature of those schemes generally mean the final candidates are the most capable, while easy or ryan's candidates are generally the ones with the deepest pockets.
And while Easy apparently seem troubled at the transition training of these 'difficult' ex TP guys the training departments of BA, Monarch, Jet2, FlyDubai, Emirates and Qatar are currently hiring ex Flybe Dash guys at a rate of 20 a month by current reports.
Just because a Trainer tells you something, does not make it true
