2. Being late or rushing to an interview is fatal, and arriving more than half an hour in advance will also be considered as having no sense of time. After arriving at the interview site, you should wait patiently in the waiting room and keep quiet and correct sitting posture.
If you want to knock, it's more standard to knock twice. Never knock too hard when knocking at the door. Don't close the door with the back of your hand after entering the door. Turn to face the door and gently close the door with your hand.
After entering the interview room, you can sit down when the examiner tells you "Please sit down". After you sit down, don't lean back against the chair or bend over. You don't have to straighten your waist, it will give a rigid impression. You should straighten your waist naturally.
When talking to the examiner, you don't need to look at each other all the time. Speak naturally, and do what you usually do when talking to others. Of course, you can't just look around.
6. After the interview, stand up and thank the examiner. Open the door before leaving the interview room, then turn around and bow to the examiner and thank you again. Then close the door gently.
