The requirements for students delivering meals are quick and sensitive. I don't know what your interview status is, so make a good impression on the interviewer. I don't think your answer to the experience in KTV is very good. This is undoubtedly a trap for yourself, because the food delivery students also need to remember the menu and know which table it is. Of course, my opinion is one-sided, and the average interviewer will wait. Three days is normal. Good luck.
