The structure of the UPSC exam process comprises three main stages: the Preliminary exam, the Mains exam, and the Personality Test. The Preliminary exam is objective in nature, featuring multiple-choice questions that assess general studies and aptitude. Candidates who qualify move on to the Mains exam, which consists of written subject-specific papers, including essay writing and optional subjects. Following this, selected candidates undergo a Personality Test, which evaluates their interpersonal skills and suitability for civil services. The entire process aims to select well-rounded candidates capable of fulfilling administrative roles effectively.
