Remember those little logic puzzles your crazy uncle used to throw your way after Thanksgiving dinner to see if he could stump you? Well, they have been given new life and function in consulting, investment banking, and high-tech industry job interviews.
Brainteaser cases can take many forms. Some are straightforward logic puzzles (for example, "If you have a drawer filled with eight white socks and 13 black socks, what is the smallest number you would have to pull out without looking in order to be sure that you had a matching pair?").
Other questions might not have a single correct answer. Instead, they may serve as a platform for you to demonstrate your creativity and ability to think "out-of-the-box." For example, your interviewer might ask you to list all the ways you could find a needle in a haystack.
It's always a good idea to let your interviewer know what you are thinking as you attack the question. Even if you don't end up with the right answer, your analytical ability will be on display. Also, if you do start down the wrong track, your interviewer may be kind enough to nudge you down another path.
