The national examination interview is usually 1 round in the morning and 1 round in the afternoon, twice a day and closed at noon. All candidates are divided into several groups by drawing lots, and each group of candidates is interviewed by the same group of examiners in the order of 1 and 1. Generally, you can finish the interview around 12 in the morning. But don't draw the last one in each group. You have to wait for more than four hours. You are bored and the examiner is not in the mood.
