First of all, you must dress appropriately in gfd. No slippers or anything. First impressions are very important.
Second, please speak Mandarin. Although some seniors and sisters speak nonstandard Mandarin, if you answer every question in Mandarin, your interview will definitely get extra points. After all, speaking Mandarin well is convenient for you and me. If you are full of dialects, others can't understand you, not to mention your future job promotion, even communication will be very troublesome.
The third is politeness. You have to learn to sweet talk, not because you want to make progress, but because you call your seniors and sisters hello when you meet, and you receive thanks in the group. It is a courtesy, even if you have some shortcomings in other aspects, you will get extra points in this courtesy.
Fourth, smile and answer questions. Most seniors don't ask difficult questions during the interview, such as why you want to join the student union, or which department you want to work in, what you want to do in the future, and so on. Of course, these questions they want to hear from you are from the heart, not rhetoric, and there are some old Baidu sayings that have been used by people who have been there before, and everyone knows them.
Fifth, details, if you are standing on the podium and explaining yourself wholeheartedly, please don't hold the podium, which is very taboo. If you are sitting face to face, you can put the bench back when you leave, and so on.
To put it bluntly, it is the details and your persistence. If there is no accident and there is no violation of discipline, it will generally enter.
