Good Morning,
I'm looking forward to do my Masters (in International Business or Marketing Management) through one of these universities. I'll be spending around 25000 euros on the academic fees. I wanted to know if the reputation of the two schools are good, which one is better? What are the employment opportunities after graduating from one of these. I plan to take the 18 month job search permit and avail it. Do you think I'll be able to land a decent job in Berlin or Cologne after graduating from these schools? I dont know German as of now, I will start a 3 month basic language course in June which shall last till August or September and then fly to Germany. After that, all my German skills will be what I'll have from my time in Germany...

Both schools are private - avoid them and attend a public University instead. These are free and their reputation is better.

The Ohm school in Nuremberg is a good alternative for marketing. There are some great private schools in Germany (HHL, WHU etc) but the options you have found are not so great.
