Ryanair is a great company to work albeit I only see it from a flight deck point of view. However, I would definitely give it a go. Although you'll be working very hard, the money is apparently quite good and quality of life depends very much on where you will be based. Stansted of course is the biggest base, very busy and the total opposite to, say Prestwick or Hahn where everybody knows each other. I'm sure you'll have a great time so go for it!
