Who is a role model for you?
When interviewers ask this question, their intent is to learn something about you through your answer. In other words, whom you admire says something about you. So be careful to explain your role model choice. If you just say that your role model is golfing superstar Tiger Woods but offer no explanation, you aren't sharing much about yourself. The judges won't know if Tiger is your role model because he's a good golfer, a Stanford graduate or something else. No matter whom you choose as a hero, be sure to know enough about him or her to explain what specific quality you want to emulate. Also, know that person's shortcomings (and how he or she doesn't let it interfere with success) since you may be asked about that as a follow-up question.
