Sometimes I feel like I'm part of a very tiny minority that prefers honesty in most situations. If I don't like a question at an interview, I say that I don't like the question. Or just answer the question. Giving vague answers or even lying at a job interview seems like a good way to get a job I'll not like.
This is sort of the same line of reasoning that people use to justify wearing jeans and a t-shirt to a job interview. The "should I be my everyday self" vs. "should I be a slightly-better (better dressed, more diplomatic, etc) version of my everyday self" has probably been around since the first formal job interview.
I tend to err on the side of "be slightly better, because they'll assume I'm doing that anyway, and what will they assume if I'm just my everyday self?" but whatever works for you :)
