Oh, for sure - worked in capital markets and getting any integration between the different teams was an unpleasant affair. However, it usually wasn't due to a lack of talent, but due to politics or personality - somebody who likes to say "no" a bunch, or refuses to allow some other approach. Most of the devs were grumpy, but liked the steady pay and stuck around. Probably the root of the problem - if retention became an issue, perhaps things would change?
