Group discussions (GDs) are an important part of many job interview processes. They involve putting 5-15 candidates together in a room to discuss a given topic for 20-30 minutes while being observed by recruiters. GDs can be moderated, with a moderator prompting discussion, or non-moderated. Preparing for GDs involves learning about potential topics, practicing applying knowledge, and developing strong active listening and discussion skills. Key guidelines for non-moderated GDs include staying focused on the topic, listening to others before speaking, avoiding domination of airtime, and reaching a group conclusion.
