The UPSC selection process consists of three main stages: the Preliminary Examination, the Mains Examination, and the Interview (Personality Test). The Preliminary Examination acts as a screening test, featuring objective-type questions that assess candidates' general knowledge and awareness. Those who qualify proceed to the Mains Examination, which consists of written papers testing various subjects and essay-writing skills. Finally, successful candidates are interviewed to evaluate their personality traits and overall suitability for civil services. Each stage is critical in determining a candidate’s potential for a future in public administration.
