Have your read the book Pedigree? It's about how people get these type of jobs written by a Kellog Professor. A lot of gatekeeping. Our society is not merit based.
The world is biased towards good storytellers. I highly recommend reading Lauren Rivera's Pedigree. It's published in 2015 and resonates with my friends in consulting and finance.
