The weightage of the interview in the final score of the UPSC exam is approximately 275 marks out of a total of 2025 marks. Although it constitutes a smaller percentage of the total score, its significance lies in evaluating a candidate's personality, communication skills, and overall suitability for public service roles. This stage assesses attributes such as leadership, integrity, and awareness of current affairs. Thus, candidates must prepare holistically for the interview to enhance their chances of success.
