Yeah i was asked this question in Water Resources Engineering position: "Tell us your two weakness". Its one of those questions where you have to throw a curve. I guess this question is generally asked to see how we can handle any shooters with tough questions.

My Curve throw: "Well i would say when i am stressed, i don't eat good. Since i would have my priorities to finishing my jobs, i eat unhealthy foods and just get blooded. During stress from work in wrapping up the project  i sometime miss my morning jogging hours which i promised to do it regularly."

Their response was "Welcome to America, you changed your lifestyle to an American way". I got the offer call next day.
