On the opposite side, I usually skip teams for their repo so I can review them. Are there test cases built out? Do they have east to follow code design, or descriptive comments? Do they have a normal level of abstraction, or are there multiple layers of interfaces for not real reason? I recently declined a position because the team was building a UI, didn't have a CMS, didn't have any real rests, and the code looked like a bit of a mess. It didn't help that the languages (Go, React) were completely new to me, so I wouldn't be able to make an impact on improving these issues.
