Brain Teasers...

John Kador has some good brain teasers on his site. For those who may have to take a brain teaser interview his book will help to get you more comfortable with this process.

As a fun teaser I saw used some time back try this one out:
Three switches outside a windowless room are connected to three light bulbs inside the room. How can you determine which switch is connected to which bulb if you may enter the room only once?
