I once asked a question like this for an interview. "Tell me what happens when you press the Buy button on a web site". It really helped me gauge a sense for the person's interests and expertise. Like some folks just talked about javascript and some node code. Others talked about tcp a bit, some got into cloud stuff. It was really telling. Not bad or good, just a great way to learn where someone's head is at and was a fun back-and-forth conversation.

This web site is basically a cheat code for that question lol. So well done, kudos to the author. Bookmarked and shared
