I remember either seven or nine, with the examiner in the middle. Last year, I interviewed civil servants in Anhui province, and only recruited one position, and I was waiting for the exam in an examination room with more than 20 people from seven or eight positions. The examiner is randomly selected from the examiner's library, and he will not receive a phone call the night before the exam saying that he was selected as the examiner. Under normal circumstances, there will be staff of the recruiting unit, but this is not necessary. There are also social supervisors, timekeepers and scorekeepers in the examination room.
Don't be nervous, play well and wish you good luck!
