The interview stage of the UPSC exam, also known as the Personality Test, assesses a candidate's suitability for civil services. It comprises a panel of experienced members who evaluate a candidate's personality traits, communication skills, and general awareness. The interview typically lasts about 30 minutes, where questions range from personal background, current affairs, and hypothetical situations to psychological aspects of decision-making. Candidates' demeanor, confidence, and ability to handle unexpected questions are crucial in this stage, aiming to assess their adaptability and thought processes.
