Aspirants can enhance their communication skills for UPSC interviews through several effective strategies. Participating in mock interviews can simulate the exam environment, helping candidates gain confidence. Engaging in group discussions on current issues can foster better articulation of ideas. Reading broadly, especially on contemporary topics, improves vocabulary and provides content for discussions. Regular practice of public speaking helps improve clarity and poise. Finally, receiving constructive feedback from peers or mentors can pinpoint areas needing improvement, further fortifying communication skills.
