The format of the Personality Test conducted by UPSC is an interview process that lasts approximately 30-40 minutes. It assesses a candidate's personality, intellect, and suitability for a career in civil services. The test panel typically consists of experts, including a Chairman and members from varied backgrounds. Candidates are evaluated based on their responses to questions concerning personal background, current affairs, and general awareness. Unlike the written exams, this test emphasizes the interpersonal skills, attitude, and decision-making abilities of candidates, which are crucial for effective governance.
