Practice is the key to a confident delivery of your answers. Take a look at the list of questions you compiled and practice your response to each question. Ask a friend to critique your performance, or record yourself and listen to your answers. It is important that you answer each question completely and provide facts, figures or other information that back up your answer, if possible. Pay attention to your tone when you answer questions. Aim for a calm, positive tone, no matter what subject you discuss.
