I once did an interview where I described some software I had designed and built that was deployed around the world.

At the end of it the biggest burning question they had was "where are the unit tests". I was like ... you see this circle here with this label inside it? This was critical to the entire system and therefore had unit tests surrounding it.

didn't get the job, they seemed kind of annoyed that I didn't get into great detail about things like unit tests and instead talked mostly about the architectural problems I solved.

I wish companies actually valued that level of knowledge.
