**What role do group discussions play in preparing for the UPSC interview?**
Group discussions serve a vital role in preparing for the UPSC interview. They create a platform for candidates to articulate their thoughts and debate diverse viewpoints on current affairs and socio-economic issues. Through collaborative dialogue, candidates develop critical thinking skills and enhance their ability to present coherent arguments. Constructive feedback from peers helps identify areas of improvement, such as communication style and confidence. Group discussions also simulate real interview scenarios, helping to alleviate anxiety.
