Echoing the statements that others have made, I think this is a crappy question. When I get asked it, I tend to ask straight back what the interviewer means by 'failure'. Usually they have their own slant on it, which means you can answer pitch your response correctly
If I failed at something - as in made a mistake, for which I then corrected, I don't consider it a failure - it's called learning. If I failed at something, and didn't learn from it, or at least didn't learn how to correct for the failure, then I probably didn't know I failed at it - and I certainly wouldn't be able to articulate anything about it.
