I concur 100%. I’m close to one particular IB’s recruiting pipeline because of some history there. Not only do they go out of their way to avoid taking nothing but business/econ/finance type majors, they put all of the new hires through a multi-week boot camp. They’re taught everything from finance to accounting to Excel modeling to global trade, currencies and interest rates, Series 7 (and 3 and 63 if/as needed), Black Scholes, etc. The expectation in this boot camp is that kids are starting more or less from scratch (and in fact, some kids from, ahem, certain undergrad ‘business’ schools wind up having to learn things the correct IRL way).
ETA: wanted to add that SB1 SUCKS. What a dreadful situation. Idiocracy in motion.
