It’s a weird dichotomy because you get the overachieving MBA types and the “my dad founded the company” types you’d expect. However you also get these unassuming types that just have undergrad business degrees from middling schools, but due to the dumb luck of being in the right place at the right time they end up with a CV that makes them attractive for the c suite and then it can snowball pretty fast. That’s what happened with my FIL, got a job in the early eighties in a bank, they stuck her in the computer banking department (which in those days was not where the hotshots were), but then the nineties roll around, the first big wave of tech startups, suddenly “banking plus computers” background is a hot commodity. Voila, she’s in the c suite.
