Yours was a clever answer to a stupid question. Tech interviewers need to leave college behind and start treating candidates as professionals. Puzzles, white boarding and riddles are unique to software engineering roles, you would never see a lawyer, an accountant, a doctor, or engineers in other disciplines going through any of this nonsense. These methods are proven to be a poor predictor of job performance. In my last role as lead engineer we would chat with the candidate over lunch about random topics. We first wanted to see if they would fit our team. Then in the afternoon let them work in a little project that was actually part of active development. This way we discovered that most candidates who went through the screening process could actually be pretty good team members. Our issue was having to decide who to give the offer to, while other companies keep rejecting candidates over bubble sort. Our attrition was also pretty low. So it happens that software engineers will surprise you when you treat them as grown ass adults. Who would have guessed?
