Mock interviews can provide invaluable insights into UPSC preparation by simulating the actual interview experience. They help candidates identify their strengths and weaknesses in communicating their thoughts, allowing them to make necessary adjustments. Feedback from interviewers can inform areas needing improvement, such as clarity, confidence, and articulation of perspective. Engaging in mock interviews also alleviates anxiety associated with the real interview, enhancing candidates' ability to manage stress and think on their feet. This practice allows aspirants to refine their narrative and better present their experiences and motivations.
