Group discussion is used in jobs and education. It tests skills like leadership, teamwork, and communication. Topics can be current issues, abstract ideas, or case studies. Speak clearly, listen actively, and use good body language. Respect others and avoid personal fights. Interviews are another way to test personality and skills. Different interview styles include panel, behavioral, and group. Employers look for confidence, integrity, teamwork, and quick thinking. Prepare by researching, practicing answers, and boosting confidence. Dress well, stay polite, and carry needed documents.
