Volvo claims it's one of the safest cars in the world because fewer people die in a Volvo than in any other car manufacturer. As a consultant, how would you answer this question not knowing the accuracy of this information?

A hiring manager will pose a question like this to gauge how you will respond to facts and data that you are not able to provide at that moment in the interview. This is mostly used to see if you answer incorrectly by guessing, or taking a more prudent approach and answering more analytically which should be the correct approach. This approach will tell the interviewer that you are honest, and think through all your responses in a logical manner, and base your response on data driven facts that can be proven or verified. In order to show respect to the interviewer, I would compliment them on asking this question to you, and follow that up with how the interviewer wants you to answer that question. They might want you to explain a process you use to validate the information or ask additional questions to learn more before responding.
