2. Leaderless group discussion refers to a temporary working group composed of a group of candidates to discuss and make decisions on a given issue. Because this group took the initiative on the spur of the moment, no one was appointed to be in charge. The purpose was to examine the performance of the candidates, especially to see who would stand out from them, but it didn't have to be the leader, because it needed real skills and confidence, and it also needed to be fully grasped.

Leader-less group discussion is a common evaluation technique in the evaluation center technology, and the candidates are interviewed collectively by scenario simulation. The Leaderless group is a group of a certain number of candidates (8- 10), and the time for discussing work-related issues is about 1 hour. During the discussion, no one is designated as the leader or the position where the subjects should sit, and the subjects are allowed to arrange their own organizations to evaluate whether the candidates' abilities and qualities such as organization and coordination, oral expression, debate and persuasion meet the requirements of the proposed positions. And whether the personality characteristics such as self-confidence, enterprising, emotional stability and flexible response conform to the group atmosphere of the proposed position, so as to comprehensively evaluate the differences between candidates.
