Similar story: I had an interview for an internship at a trading firm, in which they asked me several questions that I wrote (for a math competition at my school). I took the honest route and explained that I had authored all these problems, leading to the interviewer getting so annoyed that they just cut the interview early.

Unsurprisingly, did not get an offer.

How about being interviewed using your own book, but the interviewer didnt notice authors name on the cover, doesnt understand the questions and butchers the problems? ;-) Happened to Elecia White (of https://embedded.fm/)
