Effective communication is crucial for UPSC aspirants, as it enhances their ability to articulate thoughts clearly during both the written exam and the interview. It involves not only speaking eloquently but also actively listening and engaging with questions. Strong communication skills help candidates convey complex ideas simply and persuasively. Practicing public speaking, engaging in debates, and participating in group discussions can sharpen these skills. Mastering the art of concise expression aids in writing effective answers under time constraints. Ultimately, good communication fosters confidence and makes candidates more appealing to the interview board.
