Svantaggi
Let's first talk money. As a tester, your salary is ridiculous for a city like Dublin, one of the lowest salaries I have seen in this city. You can easily get more anywhere else. The contract you will get will depend on needs. Do not expect to become permanent there, they already have everyone they need as permanent, unless you get extremely lucky and they happen to lose a permanent tester for your language (it happens but it's rare), otherwise you can get a few weeks, a few months, to a maximum of 18 months of contract, then you will have to go. You can know if you get extended on your last week of contract, even if you ask the manager before, they rarely know before. How good you are doesn't matter, you are just a number there. Working there also means some months, you will be on shifts and work several weekends in a row. You do not get paid per se for the overtime, you get hours in the system to use whenever you want or they will pay you some of it every few months... Management is a joke, permanent only care about themselves, not the team or the quality.
