An interview is a two way process. Your interviewer wants to find out more about you to see if you are suitable for their school or company. You want to present your skills in a way which is attractive and also want to find out whether the school or company is an environment in which you can thrive.
Interviews are conversations: both sides need to take part!
Speak to friends who are currently studying at the school. They are the experts!
1: Think about what you really want to get out of the interview. Why do you want to join this school?
2: Think about what skills and talents the school is looking for
3: Think about what you have to offer
4: Ask yourself: what don't I know about this school? Some questions you will be able to research online or find answers through asking friends. Other questions will be only answerable by people within the school. These form the basis of your questions.
Once you have done some planning, the whole process becomes much less frightening. It is also worth bearing in mind that not everyone is a natural interviewer; they may be as worried as you are!
