Prepare yourself for your interview by reviewing your CV and thinking through your answers to questions a potential employer may ask. They may ask questions about: past experience, future plans, your strengths and weaknesses and why you are applying to spend the summer in the U.S.
You may also choose to practice your interview with a friend! Get dressed in your most professional looking clothes and have someone ask you questions about your CV and your future plans. Thinking through your answers and practicing your interview skills ahead of time will help keep your nerves at bay during the actual interview and it’s a great opportunity to continue to practice your English.
