Aspirants can effectively present their thoughts during group discussions in interviews by adhering to several best practices. First, they should ensure that their contributions are relevant and concise, focusing on the topic discussed. Using structured arguments that are easy to follow can help maintain clarity. Listening actively is crucial; it allows candidates to build on others' points and facilitate deeper discussions. Noting the viewpoints of peers may also inform their responses. Additionally, demonstrating respect for differing opinions and exhibiting confidence without being overbearing can enhance their presence in the discussion.
