 The second biggest mistake for people to make in-the-job interview is not asking clarifying questions correctly. For example, in the product manager interview, it's likely they're going to give you a case, product design case. The case question could be design a kitchen or design a dating app. Could also be design an Uber app for blind people. All those are typical product design interview questions for all the way to fan levels to startups. They will ask you those kind of questions all day long. But the number of biggest mistakes that candidates interviews always ask the wrong clarifying questions. For example, if I asked you to design a kitchen, I literally had heard a candidate say, design kitchen for who? Tell me. It's for what type of kitchen? You mean commercial kitchen or home kitchen? So tell me what type of kitchen you want me to design and then I can design for you. This is a wrong clarifying question up front because you basically ask the interviewer how to decide the customer segmentation and the prioritization of customer segmentations as well.
