My mother-in-law worked her entire career in an IT department of an insurance company. She never really did much programming, but became a source of domain knowledge over time.
She has all kinds of amusing stories of ye olden days. Before a proper computer system, everything was stored in physical documents of course, and her first project out of college was traveling to satellite offices to re-organize the file systems there to match the new strategy that HQ had come up with. The business of satellite office would grind to a halt while a team of people literally took every single document out, re-labeled it, and put it back. The whole project took over a year.
Given how banks were pushing the limits of paper back then, I can't imagine the complexity of a modern banks. I just don't know enough about finance to really even have an idea of where.
