I can testify that this is not extreme at all. It's almost an inevitability at every medium to large company that develops software, including but not limited to banking and finance, retail and engineering.

I have experienced silos at companies claiming to have flat management structure, to be cutting edge, agile, modern and trendy.

Even within silos of teams, there will be sub-silos: specialist developers, analysts and qa, each of which will be lugging their personalized mental-model of the system around and more often extending it using the same patterns, instead of maintaining and correcting the older stuff.

"Hey if the tests pass, it's fine. Right."
