I agree with dagmx.

However, I'd carve out an exception. In an interview where you have, without a doubt, not done well and there's greater than a 80% chance that you feel you won't proceed, this question may potentially be a good hail mary, for salvaging the interview.

But, I've never used the technique before. And unless you have alot of interview experience, it will also be difficult to make judgement calls on how well or bad an interview has gone.
