I've seen the degenerate states of both extremes: - a monolith with too many engineers contributing: no continuous deployment but rather "release day," which was a shitshow; said day was an extensive process where hundreds of engineers (anybody who was on git blame) had to be online and sitting by for four hours while it rolled; the release team often had to hand-revert bad patches; bullying of engineers who "broke the build" reached levels that would raise HR eyebrows; there were still often rollbacks and site breakages. - microservice hell: there were often 2-3 APIs for the same service; platform engineering (for the protobuf RPC generation) had to support five different languages; security auditing was NP-hard; every team had its own release process; services that were still highly used were "deprecated" and left languishing for years until somebody took up the mantle and released their own parallel service that did nearly the same thing but with a different API, so now other services had to use both; etc. "But that wouldn't happen at $my_company, we know the pitfalls and we'd never be that bad at engineering!" Sure...sure. That's what these companies said to themselves

At a company we as a dev team had to maintain a constellation of desktop applications and homemade ETL Airflow-like software that scaled really badly. For the time I'd been there I had managed to automate deployment almost totally on my own. Sadly it had been somewhat controversial as it was done at the expense of other development tasks (my manager agreed but not his nontechnical manager), and probably too late too. Before I had had enough grasp on the complicated context we had to deliver on a big project and needless to say it was a shitshow and we developers took basically all the blame, with pretty much nothing to say back.
The tech stack and code had been in a state of neglect for 8+ years but that was not an acceptable answer at that time, it seemed, and I'd only been there for 6 months when it happened.
On the other end of the spectrum, at the above's parent company, I had to maintain several major versions of an API on several cloud regions. Undocumented peculiarities regarding the object storage that was specific to one region caused a production incident that took the dev and support team 3 days to untangle and solve.
I have similar stories on monorepo vs. multirepo too
