I know a friend who got a job there. Many teams do not do any coding at all. Like most banks they have automated away all the programming and have little need for new tech.
Depending on when your pal worked there, they were in the middle of a huge standardization process. I'm not sure what's going on there anymore, but they made a company wide effort to only use a single infra framework that handles deployments, testing, infra, and all kinds of other stuff. All the fun stuff has been farmed out to a few enterprise teams and everyone else was forced to shut down anything custom.
Friend currently works there and has worked their for a year. A year of no coding sounds rough, but I guess he isn't jumping cause he is worried about the pending recession.
