I always ask this, but not for the reason you think: it's so that I, as an interviewer, can adapt the interview to you. Recent example, one candidate had no idea what I meant by "principle of locality", but I probed a bit, and he understood it perfectly well: but lacking a formal CS education, he didn't have the vocabulary. Same with big-O notation, some guys have never heard of it, but show them a code snippet and they'll tell you straight away how efficient it is.
