A Good Question

I caught the end of the talk by David Brooks on Minnesota Public Radio's presentation of the Aspen Ideas Festival. He presented a question he learned from someone who does a lot of hiring. "What is the one question you ask," he asked the hiring expert, "that gives you what you want to know." The answer:

When did you tell the truth even though it hurt you?

I'm impressed by the thoughts this can raise. I have a hunch that many would probably be taken aback by the question. It is a surprising way of finding out what kind of a person the interviewee is.

I wonder how I would answer it in a quick response?
