Group discussions are used in selection processes to evaluate candidates' ability to work in a team, communicate effectively, and think critically. There are different types of group discussions, including factual, controversial, abstract, and case study discussions. Recruiters look for candidates who begin or conclude discussions with good content, listen to others, communicate clearly, and build on others' points. Effective group discussion requires preparing by thinking before speaking, speaking concisely while showing interest in others, taking an objective stance, and citing evidence to support arguments. Participants should avoid forcing views, interrupting, bluffing, or going off topic.
