The key is temperament. You should have that kind of comfortable temperament and affinity. Show eight teeth when you laugh, and your weight and height should not be too high or too low.
Also, if you really go for an interview, remember to observe the people around you. If everyone in your group is taller or shorter than you, that is, you are too special in a group, remember to find a way to change groups, because the judges will brush out the most special first, because they are looking for the most special person among ordinary people (a very abnormal reason).
Don't wear heavy makeup, but highlight your eyes and lips. Dress yourself with spirit and temperament. You can refer to the image of a flight attendant, but don't imitate it too deliberately. Also, when you answer questions, you must be measured. If you have an English interview, you should speak more if you are good at English, but enough is enough. If it's not good, just get to the point and be brief.
Also, don't show yourself too much, which will only lower your score.
