This is the worst possible advice. It shows you are a narcissist, incapable of learning from experience, incapable of accurate self-analysis (identifying weaknesses or areas of improvement). It also shows you struggle with soft skills, because you have completely misunderstood the point of these questions and are treating them as an opportunity to 'win' the question or 'beat' the interviewer. You are showing that appearing clever is more important than being smart. You think the questions are beneath you, you think honesty is beneath you, and that interactions between people are defined only by the letter of the law and not its spirit. You know very well the intent of the questions, but you play games with your answers? No one is looking for an answer here that says "I have no weaknesses and have never failed". Which would be a better and more honest answer than the "clever" answers you are suggesting. You might as well be saying "I decline to answer because I am too smart to answer this question. Where's my signing bonus, will I be receiving it today, before the end of this interview? Because I have won, yes? I won the question by giving a non answer that makes me look great, so I am the cleverest! Therefore you must make me an offer immediately, yes? Because I am so clever! I beat the test! I beat YOU!" a/k/a "no hire". Follow this advice if you wish to remain unemployed or (arguably worse) hired by an idiot, into a team of fellow idiots. Which if you answer this way is where you belong.
