Whenyou first join you'll get messed around a lot by the training department and will probably take you around 2 months before you're finished. Why? Because of the fact they are hiring so many people and only have 1 sim and a limited number of instructors. Once you've got over that hurdle and tour on line it's good fun.
There is a very low turn over with pilots at Ryan Air and I've been told that if people leave they join outfits like Emirates. So if you plan on staying in Europe and you enjoy flying, Ryan Air is the place.
