Aspirants can develop their oral communication skills for the UPSC interview through several effective methods. Engaging in mock interviews with peers or mentors simulates the actual interview environment, providing immediate feedback for improvement. Regular practice in articulating thoughts on diverse topics helps boost confidence and clarity in responses. Participation in public speaking events or local debates sharpens articulation and poise. Additionally, recording oneself during practice sessions can help identify areas for refinement. Joining workshops and training programs focusing on communication skills also nurtures effective expression, empowering candidates to present their views confidently during the interview.
