 The fourth type of interview question the TikTok is, product metrics and execution interview questions. For example, question 12, what's the success metrics of your current project? Question number 13, as a product manager at TikTok, how would you know if this product is good or bad? Question number 14, how would you embed new technology to TikTok live shopping? Regarding those product metrics interview questions, I highly recommend you guys to use my computer science PhD framework, embedded by me, Dr. Nancy Lee. So what this stands for is, you must start with why admission of this company and customer segmentation, CS, and then PhD stands for prioritize metrics, which means your newer star metrics and product health metrics and the de-risk metrics, and all those metrics are very critical for you to give a very comprehensive answer to those product metrics and define success and different kind of goals questions.
