Note: Not at Uni yet. Skip past if looking at more serious answers.
University and degree: Probably economics at a target. Considered maths and other subjects but tbh I'm not that interested in what I'd call a 'rigourously' numerate role and therefore can get away with something more the middle of the park that better suits my interests (game theory, behavioural economics, international relations).
Division I want to apply/have applied to: It'll be M&A. I'm interested in M&A. Maybe TMT or other coverage groups at banks who deal with M&A differently like GS.
Reason(s): Deals. The market itself does't really pique my curiosity. What does is how we might structure and/or negotiate between companies, evaluate a company's assets, whether it's worth acquiring, how to do so most effectively, etc. Longer game but much more to my liking than, say, trading which is an adrenaline rush, I'm sure, but I'd get lost after a while with a want for more forward thinking. Analytical, yes, but I need it in a more strategic sense.
How long I want to stay in banking: Buyside M&A seems to be where you can exercise a little more creativity so maybe there ASAP but I wouldn't mind staying in banking for the long run (he says. lol) if the work is as exciting as I hope. Looking forward to client related stuff later on in M&A too so maybe I'll stay on depending on whether I can deal with being a full time sycophant.
If I don't like it in banking or decide it's not for me when doing an internship law, consulting and military are a few viable options depending on my feeling at the time.
