Investment Banking and Other Jobs?

I think the person above answered the questions pretty well. It's a really tough job, very stressful and the hours are REALLY long. One my first day as a grad trader my boss said that he hoped I had said goodbye to my friends and family as life as I knew it "was over". He was very right. 90 hour weeks and no breaks. As for a degree get a hard science degree (physics is great, phd is even better) from the best uni you can get into. This is the best paid industry in the world and competition for jobs is incredible.
