Puzzles are a really good measure of one's analytical skills and lateral thinking. Many product-based companies ask the puzzles to help them filter candidates based on their real-world problem-solving skills to approach a problem they have not seen before.

A puzzle may have multiple solutions, where the interviewer is generally interested in the candidate's approach to not only solving the puzzle but the approach to building and thinking creatively for the solution to the puzzle.
