To prepare effectively for the UPSC interview, candidates should focus on self-awareness and current affairs related to their field. Conducting mock interviews with peers presents an opportunity to refine responses and receive feedback. Understanding one's bio-data, interests, and opinions is crucial, as interviewers often probe these areas. Candidates should stay informed about recent national and international developments since these are likely discussed. Practicing concise and articulate communication is essential, as clarity and confidence can positively influence the panel’s perception. Ultimately, a balanced approach combining preparation and spontaneity will enhance interview performance.
