This is an operational question. Interviewers at YouTube will ask operational questions to determine how you complete the tasks required by this role.

"During my software development career, I've tried many different design patterns. These include Singleton, MVC, and Template. However, the one I prefer and use most often is Iterator. This helps me code in an organized fashion and reduces the amount of time to develop the software. It also results in fewer errors and less debugging."
