They contacted me through email to ask for a date/time for a phone interview. I received the call and they asked me about several things, among them, my immigration status, I never heard of them again. I know that they won't call me again because I do not have a permit to work in Ireland (I discover that thanks to a competitor of Adecco who was nice enough to explain me the situation). I know my limitations when it comes to applying for jobs abroad, but the least they can do is being honest about the possibilities or at least send me a rejection email.
