Are you talking about MBAs or M.A./M.Sc. degrees in related fields? Personally, I do not even consider MBAs to be much of "a thing" in Germany. Yes, there are some prestigious universities offering them (St. Gallen comes to mind) but many people still have not moved on to the Bologna System from the good old "Diplombetriebswirt" in their hearts, let alone MBAs.
