I'd probably answer, "My total lack of respect for people who ask stupid interview questions. Are we done here?"

I do as many lists of answers will tell you to do. Try to make it a positive.

I tell them that I'm a perfectionist and that sometimes bothers some people. Which is true, and they always seem to like that answer.

When it comes to answering "none", it probably all depends on how you do it. No one wants to hire arrogance, but if its an honest assessment and you just can't think of anything...

As Brian pointed out earlier, it's a kinda dumb question to begin with, designed to see how someone reacts and judge honesty/humbleness/etc.

"kryptonite" is still my favorite response though ;)

It is like in a movie "office space": -" I am good with people, I have good people skills, don't you see; what is wrong with you people" )

Too personal question.(but not answer like that)

I would say, that you just have to show HR person that manageable without them knowing personal side of your life. If your title going to be higher than HR, than you need to show them that(if you hired) you would not ask them personal questions as well)))))))

Greatest weakness? Admiting that I cant break higher ethical principles in order to benefit my company-organization or even self when it becomes materially vital for that system you are part of . To declare that you will always hold higher ethical principles above the self centered utility of the company you are part of although you are flexible enough to realize that on occasion it may be proper to compromise a weak ethical standard to achieve a higher final one (end justifies means only if the ethics you sacrifice during the process is recovered eventually at a larger scale). If it becomes a choice of preservation of maximal company utility (ie profits) at the expense of a significant ethical principle you will have a hard time compromising and likely will not. So you shouldnt be part of a mechanism that requires corrupt action design. Strong second a never ending desire for analytical thinking that can show you as opinionated and show excessive focus on the complexity of things.
