Atse - the backlog in training has largely been cleared and pilots are no longer experiencing delays in line training or getting a check ride.
Also new pilots are paid from the first day of training, so even if there is a delay it is not "unpaid" as you state.
Finally the employment contract is signed by both parties before type rating training commences, so you're statement "You certainly will not be given a contact guaranteeing you employment. Assessment and providing type-rating to prospective pilot employees is not necessarily linked to employment in Ryanair" is completely false.
You're entitled to your opinion but please get your facts right.
