State services exams differ from the UPSC Civil Services exam primarily in terms of scope and structure. While UPSC recruits for all-India services, state exams focus on local administration and governance. The syllabus for state exams may be tailored to specific regional issues, unlike the broader national perspective of UPSC. Moreover, the selection process content, exam patterns, and eligibility criteria can vary significantly, making each examination distinct in its objectives and assessments.
