Why would originality be a concern, if the question is good and cannot be "prepared in advance"? I believe that the question is not meant to be asked without follow-ups, or deep dives in specific areas (maybe asking the candidate where they want to focus next). I agree that if the question is asked without entering a two-way discussion, then it's useless. In the interest of a constructive discussion, why do you believe that a URL shortener is a bad interview question?
