They might have competent people but most tech people working at a bank like are out of fucks to give.

At these massive, unable to go bankrupt companies, you quickly lose all fucks to give. No one cares about opinion of ICs or even direct managers, Senior Management makes the calls and you either execute quietly or replaced with someone who is. When I worked for $MegaUSBank, there was two types of people. Those who realized their "spark" was draining out of them and got a new job after a few years and those who were just "Whatever, I push buttons and get paycheck." and had been there for 15 years.

This isn't exclusive to megabanks, either.
