Previous civil service experience can significantly impact UPSC interview performance. Candidates with relevant experience often demonstrate a deeper understanding of administrative processes and governance issues, which can impress the interview panel. Such backgrounds provide them with practical insights into public service challenges, enhancing their answers during critical questioning. Additionally, experience in handling responsibilities can improve their confidence and articulate communication. However, while beneficial, it is essential for all candidates, regardless of experience, to showcase genuine passion and a commitment to serve effectively in civil service.
