I've just graduated and I'm about to get into investment banking, in fact, I just had a meeting with an agency today. Should I be worried @Theraflu ?
No, you'll be fine.
Just do as @newworldafro said and work for a few years then leave.
A lot of the few black dudes I met when I first left college left after 2 years to join other places. One works for the UN now the other moved into Journalism.
So use it as a stepping stone. My mistake was not creating an end goal or plan, I wanted to stay till M.D level but it's really the kind of environment where you save, get your contacts and get out.
