This is maybe the most important point. This developer clearly did not know how muddy the technical stack was at this company when joining. Sure, every organization has different standards, but related to that is what the desired standards are. In this case, it's clear that internally those were the desired standards. I think that raises the issue that during interviews, it's important to reliably find out a) what the state of code is and b) what the real standards are. It would probably be better to work at an organization with no testing that wants complete unit test coverage, than to work somewhere with a test environment that is happier with poor coverage.
