The UPSC pattern differs for Civil Services and State Services examinations primarily in the scope, syllabus, and exam structure. The Civil Services Examination focuses on selecting candidates for All India Services and central services, while State Services examinations cater to state-level administrative roles. The UPSC examination typically involves three stages: the preliminary exam, the mains exam, and the interview. In contrast, State Services may have variations in their selection processes and specific eligibility criteria, reflecting the distinct requirements of different administrative levels.
