Pros
A good way to start and gain experience in aviation. Wage could be worse, even if life in Dublin is really expensive. You may become number 1 easily after one year and increase your wage about 400-500 euros more. The roster is fixe, five days on three days off, which can be quite satisfying if you look for stablity in aviation. You will always come back home the evening, except if something happens, like an aircraft damage when then you will overnight.
Cons
Exhausting. You will provide many hours for this wage, Dublin is one base when you can evolve and earn more quickly but it is not the same for every bases accross Europe. Ryanair unfortunately provides different conditions depending on the location. Ryanair's system is completely disorganised, which means that some people not all the time better than others will be selected to become number one or to get the transfert when the ones doing their best won't be rewarded. It is not a pattern, but it is way too much a matter of luck and people you will get in touch with. You will have to fight and beg for every favour you will want, like unpaid leave or flexible roster. You will also work one week on earlies, start at 5 lots of morning, and work on lates the week after, finishing most of the time around 11-12pm. As said before, exhausting.
