Common misconceptions about the UPSC interview process include the belief that it solely tests knowledge rather than personality. In reality, the interview evaluates communication skills, emotional intelligence, and decision-making under pressure. Another misconception is that success in the written exams guarantees a good performance in the interview. However, spontaneity and genuine engagement are often more important. Finally, the idea that candidates must have extensive knowledge in every subject misrepresents the interview's focus on a holistic understanding and the candidate's ability to express thoughts clearly.
