Group discussions involve 8-12 members discussing a topic for 20-30 minutes. They assess personality, communication skills, leadership, and more. Good discussion skills include preparing, actively listening, supporting views with facts, maintaining cordiality, and avoiding interruptions or changing opinions. Participants should be assertive but not hurt others, accept criticism politely, show leadership, and suggest ideas without blaming. Common topics discuss issues in technology, society, culture and India's development.
