You will be asked many questions during your required interviews. Your interviewers may be friendly or hostile, straightforward or apparently friendly but bent on tripping you up. Make your answers straightforward and sincere. If you don't have a good answer in your own mind, it's all right to say that you haven't arrived at an answer for a particular question.
Nobody knows all the answers.
The questions below are real. They have been asked, along with thousands of others. You won't be asked all of them. You may be asked none of them. But you, your counselor, and your friends can use them to prepare for your interviews, or to help in preparing your CO statement.
