Role-playing techniques can assist with preparing for the UPSC interview format by simulating real-life scenarios and encouraging spontaneity in responses. Candidates can practice articulating their viewpoints on various current affairs or ethical dilemmas in a safe environment. This method cultivates confidence and enhances communication skills, allowing for smooth interactions during actual interviews. Engaging in mock interviews with peers or mentors can provide constructive feedback, enabling candidates to refine their responses and presentation style. Additionally, role-playing helps in managing stress and developing quick-thinking skills, vital for performing well under pressure during the UPSC interviews.
