I have...been asked maybe one of these questions, and that when I was interviewing for an internship at a defense contractor. None of the others have ever come up. Even the place that used DDD (badly) didn't ask about it during the interview. Now, to be fair, I -have- asked if a person is familiar with CAP. But only as a way to determine if that is a relevant communication framework for discussing distributed problems/solutions; a "I haven't" isn't a ding against them, but a place to provide some context for the upcoming questions around distributed system tradeoffs.
