This is a brain teaser designed to test and observe your analytical skills in real-time. It will also help them determine your strengths as an analytical or interpersonal thinker, depending on how you go about teasing apart your answer.

Try answering the question at home on your own before looking up the answer. Try to vocalize your answer as you attempt to problem solve it to practice your communication skills. Whether you find the answer to the question before the interview is beside the point. You want to go through the whole problem-solving process, communicating clearly when this question is posed.
