The UPSC determines the merit list for selected candidates based on their performance in the Mains Examination and the Interview stage. The written examination carries significant weight, with total scores from individual subjects contributing to an overall cumulative score. Following the interview, the Commission finalizes the merit list, considering both written and interview marks, subject to existing reservation policies. This transparent and systematic approach ensures that the selection process remains objective and reflects the candidates’ comprehensive capabilities and suitability for civil services.
