To enhance verbal communication skills for the UPSC interview, candidates should practice articulating their thoughts clearly and confidently. Engaging in mock interviews with peers or mentors can provide valuable feedback on body language, tone, and clarity of speech. Reading aloud while preparing can also help improve diction and fluency. Moreover, staying informed on current affairs allows candidates to speak intelligently on relevant topics. Finally, gaining experience in public speaking through participation in groups or events can significantly boost overall communication skills.
