Group discussions are used in recruitment to evaluate candidates' communication skills, leadership abilities, and ability to work as part of a team. Recruiters look for qualities like beginning or concluding discussions with good content, listening skills, communication skills, and leadership skills. There are different strategies for group discussions depending on a candidate's familiarity with the topic, such as using frameworks to structure the discussion if unfamiliar or leading the discussion if very familiar. The dos include speaking clearly, being attentive, and using data to support points, while don'ts include forcing views, cutting others off, or going off topic.
