do you think the other big banks arent doing this? Bank jobs are pretty broad, theres a ton of code getting written here.

I'm less concerned about the code and more concerned that you said there's no culture around reading it/reviewing it...at a bank.

If anything screws up, that's people's lives being messed with, potentially in a way none of the engineers on staff know how to fix. If I were an actuarial in that environment I'd blow a valve.
