NPCIL Deputy Manager Exam 2025: CBT and Interview Weightage Explained (50-50 Final Merit Rule): NPCIL (Nuclear Power Corporation of India Limited) conducts the Deputy Manager Examination to recruit candidates in various disciplines. In the 2025 notification, NPCIL has clearly mentioned that final selection will be based on 50-50 weightage of CBT and Interview marks. This means that both written test (CBT) and interview performance will carry equal importance in preparing the final merit list.

What Does 50-50 Weightage Mean?
In simple terms, “50-50 weightage” means that your CBT score and Interview score will each contribute 50% to your final selection marks. Even if you score very high in the CBT but perform poorly in the interview, your final merit may drop significantly. Similarly, a candidate with average CBT marks but a strong interview can move up in the ranking.
Example Calculation
➡️CBT (Computer Based Test) is of 120 marks
➡️ Interview is of 100 marks
Now, consider a candidate who scores:
✅CBT = 90 marks out of 120 → (90/120) × 100 = 75%
✅Interview = 70 marks out of 100 → 70%
Applying the 50-50 weightage rule:
👉 Final Score = (75 × 0.5) + (70 × 0.5) = 72.5%
So, the candidate’s final merit score is 72.5%.
Comparison of Three Candidates
| Candidate | CBT (out of 120) | Interview (out of 100) | CBT% | Interview% | Final Merit (50%-50%) |
|---|---|---|---|---|---|
| A | 100 | 60 | 83.3 | 60 | 71.65% |
| B | 80 | 90 | 66.6 | 90 | 78.3% |
| C | 110 | 40 | 91.6 | 40 | 65.8% |
👉Candidate A has a higher CBT score but performs average in the interview — resulting in the average final merit.
✅ Candidate B has a lower CBT score but performs well in the interview — resulting in the highest final merit.
❌ Candidate C scores brilliantly in CBT but fails in the interview — resulting in the lowest merit.
Key Takeaways
NPCIL uses a balanced evaluation approach — CBT and Interview carry equal weightage (50-50).
Final Merit List = (CBT Score calculated in 100 × 0.5) + (Interview Score × 0.5)
Performing well in both sections is crucial for selection.
Candidates should focus on communication, confidence, and HR/technical knowledge for the interview.
