The Nuclear Power Corporation of India Limited (NPCIL) is a government-owned corporation of India based in the financial capital of India viz Mumbai in the state of Maharashtra. NPCIL Syllabus: 1. MANAGEMENT & GENERAL APTITUDE TEST English language Aptitude test Logical reasoning Data interpretation Analytical reasoning 2. FUNCTIONAL KNOWLEDGE TEST Selection Process:- The candidates who are qualified in written test will be called on for personal interview. The final selection will be based on their marks in written and interview test combined. The interview schedule and call letter will be announced in later stage after the declaration of result.
