Effective communication skills significantly impact an aspirant's interview performance in UPSC. Candidates need to articulate their thoughts clearly and confidently, as interviews assess not only knowledge but also the ability to convey ideas. Good communication facilitates better engagement with interviewers, demonstrating a candidate's poise and coherence under pressure. Active listening is equally critical; it allows candidates to respond appropriately to questions and prompts, showcasing their analytical thinking and maturity. Mastering these skills can help aspirants build rapport with panelists, thus enhancing their prospects for selection.
