No - I'm at a large financial firm, but it's not an investment bank. So I must warn you that I don't want to unduely put you off investment banking
In fact I am still considering it as an option myself, at least just for a few years after uni.
It's not so much that I hate the type of work (I actually find it quite interesting), just that I'd rather not have the ins and outs associated with working for somebody else. But there are many people who hate the insecurity that comes with self-employment, so I know my view is by no means representative of the majority.
Are you in your final year of uni? Best of luck with your applications!
