I found pretty funny a question in a recent interview (for a Senior Software Developer position): how you can solve the problem of the ladder & the egg (i.e., lowest height from which the egg would crash) in the most efficient way? The interviewer didn't like my answer "with a custom algorithm; I would have to do some tests...", because he wanted to hear "binary search". This project is just a small application including a custom algorithm performing much better that the plain binary search.
