>>51824786You should double major and apply for an internship in a HFT firm like Optiver or Jane Street.
If you can't get into one of those try for MBB, with Mckinsey in particular as your goal.
Failing that, go for J.P.Morgan
Failing that go for consulting at a big 4 (deloitte>EY>PWC>KPMG) and do STRATEGY/Business Analyst work. Do NOT do implementation!
That's my advice for you.
