Think about possible #questions and what #answers you would give in order to be able to answer them as concisely as possible during the #interview. It is not about learning answers by heart, but about having ideas ready and appearing well prepared. It is also very important to listen carefully to the interviewer, especially since you cannot perceive facial expressions and #gestures as well as in a personal conversation. Also pay attention to your #posture, because it is important to show that you are concentrated and enthusiastic in the conversation. An upright posture makes you look confident and you do not run the risk of getting tired.
TIP: Practice this behavior during a video conference with a friend.
