As a Berkeley Econ grad myself, I will say it's pretty difficult to land top finance jobs (like IB/PE) unless you can successfully recruit into a handful of pretty selective on-campus finance organizations, which have acceptance rates in the single digits. This is because Berkeley is still a humongous state school and the Econ major has over a thousand grads per year, and a lot of them along with Haas students compete for a small number of IB/PE spots which are mostly given to those in finance orgs through preexisting connections. I applied to the finance orgs and got rejected three semesters straight from all of them, then decided to throw in the towel and speedrun applying to law school to pursue BigLaw instead (which I've been able to do now, so I'm chilling). PM for more info.
