Why is a manhole cover round?
Really?! What does that tell them about an employee?
It tells them if you can think through a problem without giving up soon and criticizing them for the question instead. The answer - A round cover can never fall inside. Any other shape can fall in. A square, rectangle, triangle, .....You can always have a way to shove it into the whole. But a diameter of the circle will never be greater than itself (unlike the other shapes where some dimensions are smaller than the diagonal)
