I'm not speculating. This all took place during a phone call so the post is completely the interpretation of the author with regard to how the recruiter answered the questions. For all we know, the author just paraphrased everything as "That's wrong" to make the recruiter look like a simpleton so that they themselves wouldn't look silly for not passing. We have no other information except for 1 side that happens to be the author's side. Others have commented that they took this same test and were told after that the person doing the interview was a psychologist that wasn't testing technical skill. That's where my speculation is based.
