Got into University of Warwick Diploma + MSc in Economics. What should I expect and what should I aim for?

Hey guys,

So I got into University of Warwick's Diploma + MSc Economics graduate program. I know this University is considered a target school for undergrad and that it is up and coming when it comes to economics.

I would like to pursue a career in Investment Banking and then go the usual path to the Buy side but in case that doesn't happen what kind of careers should I aim for that have similar pay or pay growth?

What societies/clubs should I join except finance and economics? What is the alumni like? I know the University has a great career center, is it true?

I have double citizenship EU & American if it matters.

I will reward a silver banana for thoughts, opinion, advice and other stuff.
