Speak politely and naturally even if you are feeling shy. Think before you answer any questions.
If you cannot understand, ask: “Would you mind rephrasing the question, please?" The question will then be repeated in different words.
If you are not definitely accepted or turned down on the spot, ask: "When may I expect to hear the results of this interview?"
If you do receive a letter offering you the job, you must reply by letter (keep a photocopy) as soon as possible.
Good luck.
