Call me a sceptic but I doubt it will make much difference a Ryanair. I am sure you will still need to self fund the type rating. If they did recruitment the old fashioned way then working as cabin crew may help in getting your face known but I can't see it helping in the current climate of paying for your own rating.
Judging by your name I am guessing you are in Madrid. If so then bear in mind that easyjet are probably looking for cabin crew for their new Madrid base and they are undoubtably a better employer than their Irish counterpart. The Airbus is a more useful rating to have as well for moving on if you wish to do so.
