The second principle: try to answer with the first, second and third words, and say no more than three sentences at each point.
The third principle: concise and logical, especially when eating in the morning and at the beginning of the afternoon, the answer must be loud and short.
The fourth principle: the appearance (formal dress) is simple and generous, and the behavior is dignified and calm. When answering, you should make eye contact with the examiner and try to take care of all the examiners.
The fifth principle: if the difference in written test scores is not too big, don't deliberately pursue innovation and seek stability during the interview.
Finally, good luck!
