If you’re interviewing for a tech position, I really hope you do know how the internet works.

You don’t want to spend 30-plus minutes explaining how the intricacies of how the internet works. In my opinion, this kind of question is trying to gauge your interest, passion, and, of course, knowledge.

Do you mostly talk about the server side? Do you focus on the client side only? How you talk about the internet can show not only your knowledge, but also your passion and where your interests lie. For instance, if you spend 30 seconds talking about servers but then four minutes describing how webpages are displayed in the browser, that probably means you are much more passionate about the client side.
