✅ Selection Process

The selection process for NTPC varies based on the post category (engineering, diploma/ITI, safety/environment officer etc.). The common stages are:

Online Application & Eligibility Screening – Candidates apply through NTPC careers portal; eligibility (qualification, age limit, discipline, category) is verified.
Written Test / Online Computer Based Test (CBT) – Most posts have one or two stages of online objective tests covering general aptitude, technical/trade discipline, reasoning, English etc.
Interview / Skill Test / Trade Test – For some posts (especially officer level, safety/environment) there is an interview; for technical/trade posts a practical/trade test may apply.
Final Merit & Appointment – Based on performance in CBT(s) + interview/trade test + applicable cut‑offs, final selection is made.

📘 Exam Pattern

🧮 Pattern for Engineering / Trainee Posts

Here is a representative pattern for engineering, diploma trainee, and other technical posts at NTPC for 2025:

Category	Stage	No. of Questions / Marks	Duration	Negative Marking
Diploma/ITI Trainee – Stage 1	General Aptitude / English / Quantitative / Reasoning	~120 Q / ~120 Marks	2 hours	−0.25 for wrong answer
Diploma/ITI Trainee – Stage 2	Discipline‑Specific/Technical Questions	~120 Q / ~120 Marks	2 hours	−0.25 for wrong answer
Assistant Officer (Safety/Environment)	Single stage objective test – Part A (Subject Knowledge) + Part B (Aptitude)	~120 Q / ~120 Marks	As per notification	No negative marking reported for some posts

📝 Key Notes

Duration is typically 2 hours for major trainee/engineering posts.
Negative marking: For many technical/trainee posts, wrong answer leads to deduction of 0.25 marks.
For higher‑level posts (officers) the pattern may differ and negative marking may not apply.
For safety/environment officer posts, requirement may include a single combined test of subject + aptitude.
Candidates must carefully check the advertisement for their specific discipline/trade for exact pattern.

Accuracy matters: For posts with negative marking (−0.25 per wrong), avoid blind guessing.
Revision notes: Maintain short revision sheets for formulas, important concepts, abbreviations relevant to power/energy sector.
Current affairs & energy sector awareness: For posts especially in safety/environment/assistant officer, stay updated on sector developments, NTPC projects, power generation trends.
Trade test/Interview readiness: If your post requires interview or trade/practical test, ensure you know your projects/trade tools, and practical scenarios in industry.
Time‑table & consistency: Dedicate daily time slots for each section – general aptitude, technical subject, mocks.
Health & mindset: Regular breaks, good sleep, positive mindset help sustain long‑term preparation.
