The Ryan air scheme is straight forward:
€ 350 selection fee
€ 23500 Type Qualification Training for 737 NG
the €16200 is a bankguarantee / bond that you only have to supply for the period that you do the line training and use Ryanair aircraft but are not employed by Ryanair.
Should you fail while line training you get your money of the bond back and should you decide not to take up the offer of employment of Ryanair but go to another airline only then you will lose the money.
Regarding the cost of the Type qualification. This might be relative new in Europe but it has been in use with South West for years.
