Hi - no you would not take these to an interview. You would use these to prepare before going in. Maybe it's not for everybody, but for people who are really bad at interviewing (and I've worked with a few of them) structuring their answers and thinking about them before the interview can help. There's nothing magical about cheat sheets other than the fact that using them forces you to think through and structure your answers beforehand. Maybe you already do that - in which case this product isn't for you.
