Candidates can develop oratory skills relevant to interview preparation for UPSC by engaging in public speaking and presentation activities regularly. Participating in debates and discussions enhances both confidence and articulation of thoughts. Joining groups like Toastmasters provides a structured environment to practice speaking in front of an audience, receiving constructive feedback. Mock interviews with peers or mentors allow for targeted rehearsal, helping candidates refine their responses to potential questions. Recording and reviewing their speeches can also aid in self-assessment, enabling candidates to improve clarity, tone, and engagement during actual interviews.
