Explain recursion to a 3 year old

Hello, as an MS employee I have created an interview prep guide for Microsoft interviews, based on my and my colleagues' recent interview experiences. The guide has questions you should expect along with our answers that got us into Microsoft. You can find it here: interviewjoy.com/services/interview-process-details/microsoft-program-product-manager-interview-questions-answers-details-ms/ (please do not forget to also look at the reviews at the bottom of that page). Thanks and good luck! Ryan
