Unless you go through their own academies (and even then it is not guaranteed), you don't go to a flight school to work for EK or the unmentionable- they employ experienced pilots already working in the industry.
Thus what you need to be thinking about is the path to employment before the ME airlines- and that will depend on where you are, where you can and are willing to go, and, of course, how much money you have to spend.
Your profile says Belfast but I get a sense you are not native Irish- tell us a little about where and who you are, and we will be better able to advise you.
