There is one examiner, six other examiners or eight examiners in the exam, which must be singular anyway. Only the examiner speaks, and other examiners can't speak. The examiner only tells you the opening explanation, so that you know what's going on, and then guides you to answer questions and read them to you.
Answer one question, then look at the next one, and the candidates will answer after listening, and so on.
Finally, the highest and lowest total scores of the judges are removed, and the average score is divided into interview results.
