The UPSC selection process is designed to recruit competent candidates through a comprehensive evaluation that includes preliminary exams, mains, and interviews. The preliminary exam serves as a screening stage, while the mains test candidates' depth of understanding across diverse subjects. The final interview, or personality test, assesses attributes such as communication skills, decisiveness, and ethical judgment. This multi-stage process allows for a thorough evaluation of candidates’ academic proficiency and personal characteristics, ensuring that those selected possess both subject expertise and essential qualities for public administration.
