is majoring in electrical engineering beneficial for a career in tech IB/PE

My gut reaction is not really - coming at it mainly from a recruiting point of view to break in - but if you can pull it off with a high GPA, I say go for it. Arguably a more useful/marketable degree than finance (says Gerald the finance major). I'm closer to PE recruiting now, but IB/PE recruiting has gotten crazier and crazier each year as far as competitiveness and timelines moving up...some kids were 19 this interview cycle when they locked in their junior summer internship for next year.

Since you are on Searchfunder, you may have more of an entrepreneurial/operational bent - EE is likely going to be more practical from an industry point of view and would be easier for you to credibly carve a niche out. Best of luck.

Any engineering field will give you the analytic background which makes the difference. It's also third party validation that you can do something hard. Business degrees are cheap.
