The selection process for the IAS exam comprises three key stages: the Preliminary examination, the Main examination, and the Personality test (interview). The first stage, the Prelims, consists of two objective-type papers, primarily testing general awareness. Successful candidates progress to the Mains, which includes nine descriptive papers covering various subjects, including an optional subject. Finally, those who clear the Mains are called for the Personality test, where their social skills, leadership potential, and overall personality are evaluated. This rigorous process aims to identify truly capable individuals for civil services.
