Group discussions (GDs) are used by organizations to evaluate candidates' personality traits and skills. In a GD, candidates are given a topic to discuss in a group for 15-20 minutes. There are different types of GD topics, including factual topics about day-to-day issues, controversial topics meant to generate debate, and abstract topics that test lateral thinking. Effective communication skills, knowledge of the subject, leadership skills, and thorough preparation are important for participating in and summarizing a successful GD.
