The selection process for various services under UPSC can vary significantly. Each service, such as IAS, IPS, or IFS, features distinct eligibility criteria, examination patterns, and interview assessments, although they all follow a similar hierarchical structure of Prelims, Mains, and Interview. Specific services may impose additional requirements, like physical tests for the IPS. This differentiation ensures that candidates are evaluated based on the skills and qualifications necessary for their designated roles. Awareness of these differences is essential for aspirants aiming for specific services.
