I've luckily managed to pick up on these lessons without learning the hard way. At my current job, the quality of the codebase is frankly, quite shit. The unit testing coverage is fine, but the actual quality of the code isn't good. It's not clean, there's a lack of separation of concerns, it's poorly formatted. Within the first week of starting the job, I had a laundry list of things that we should do to clean up the codebase. However, I've been slowly feeding this list to my manager, rather than just dumping it on him.
