Can a public institution be an examiner when recruiting staff in the unit?

Of course. The chief clerk of a public institution can serve as an examiner when recruiting staff, because the chief clerk of a public institution belongs to the staff in preparation. If the chief clerk belongs to the excellent logistics staff when recruiting personnel, he can apply for the position of examiner on his own initiative, thus ensuring the quality of interviewing candidates and ensuring that the recruited candidates belong to high-quality talents.
