At my work we have this program called The Associates Program (TAP). They work for us for two years and travel all over the world to our different offices working on projects. The recruiters really only go to 6-7 of the top schools to recruit for the position. They look for extremely intelligent people who are good at thinking "outside the box". The recruiters were in Boston recently and asked the following question as part of the written portion of the interview:
You have 8 metal balls in front of you. All appear identical, but one has a manufacturer's defect and weighs slightly more than the other seven. You also have a scale (one of those old school ones that weighs two quantities against each other). Your job is to find the defective ball. You can only use the scale twice. What do you do?
Think you know? Post your answer as a comment.

What? You expect me to venture a guess and post it for all to see my stupidity? Think again, sonny.
Hello David! How are you? What have you been up to?
Oh by the way, I know the answer. You start by measuring three of them against three of them. If they weigh the same you measure the remaing one vs one. If one of the first groups of three weighed more than the other, you would put one vs one on, if those were the same you kow it was the one you didn't put on. DOes that make sense. It is hard for me to type it! David are you impressed? = )
