Socio-political knowledge significantly affects candidates' performance in the UPSC interview by enabling them to engage thoughtfully with current issues. An informed candidate can articulate views confidently and demonstrate a strong understanding of governance, policy, and social dynamics. This depth of knowledge helps in critical thinking and responding to unexpected questions, showcasing not only intelligence but also personality and clarity of thought, which are vital in the selection process. Thus, candidates who are well-versed in socio-political contexts generally perform better in interviews.
