What bank would pay close to a FAANG? Goldman is the only one that I think could come close at the junior levels, but once you reach senior or above, I doubt any can.
Maybe for some elite (and pretty rare) roles in niches like algo trading, but I doubt the typical bank developer job pays as well as FAANG or other top tier tech companies.
Some elite hedge funds or prop trading shops could match or even vastly exceed FAANG comp, but then again, those jobs are both pretty rare, and their interviews can be difficult enough to make FAANG interviews look easy.
