Other than that, The thing about Ireland is that you won't easy get the Management kind jobs there. You have to start your work journey as a business analyst or something. The roles might be different while seeking a job in Management area.
But there is no such thing that you won't get job in Management field at all.
UCD is triple accredited and is a great business school.

Frankfurt School is famous for its finance course. You can't go wrong with either school.
