Be sure to dress appropriately and gracefully during the interview, and try to wear formal clothes. In addition, you must show your comprehensive ability in the interview and think carefully when answering questions. It is not advisable not to speak. You must answer intelligently and give well-founded examples to make the interviewer feel that you are a thoughtful person.
Also, don't be stressed and nervous during the interview, but smile. Sometimes smiling may give the interviewer a good impression, and it will also make the interviewer feel that you are a relatively calm person. Remember to say more polite words, such as thank you and goodbye.
