One company I worked at had "we hire the best!" as its slogan, and they used it to justify so much bad practice. No code reviews (we just don't hire people who write bad code), no unit testing (same reason), python used for huge sprawling 10+ year old codebases that's on its third or fourth generation of maintainers, and no documentation anywhere. Everything is a spelunking expedition, and there's no type safety or anything to help you figure it out. There are more than a few thousand-plus line functions that make PyCharm chug every time your touch a character.
On the flip side, the Java and C++ codebases were similarly abused (no tests, no docs, four generations of maintainers/oral tradition, no code reviews ever) but are at least two orders of magnitude easier to traverse because the type system keeps everyone honest across decades in a way that dynamic languages just do not.
