I counter with the 9-layer model and that causes them to ask a more relevant question. This happens a lot when you're receiving a generic interview from a US Megacorp that has only recently ditched irrelevant (save for "how does this person think") quizzes for cross-functional interviews from people whose function is far removed from what you thought you were going to be interviewing for. (They all seem to have migrated to this strategy, for what that's worth.)
