Effective communication plays a critical role in the UPSC interview, as it enables candidates to express their ideas clearly and confidently. Good communicators can articulate their thoughts, showcase their knowledge, and engage the interview panel effectively. Active listening is equally important, as it allows candidates to respond appropriately to questions and demonstrate their understanding of the topic. Non-verbal cues, such as body language and eye contact, also contribute to a positive impression. Ultimately, strong communication skills distinguish candidates and enhance their chances of success in this significant stage of the UPSC selection process.
