Why HPCL ET is One of India's Hardest PSU Exams
HPCL Engineer Trainee is consistently rated among the most competitive PSU exams in India. Unlike BHEL or Coal India where GATE score alone can secure selection, HPCL runs its own CBT — and the technical section is set at near-GATE difficulty. The competition is fierce: tens of thousands of engineering graduates apply for a few hundred seats across five branches.
HPCL also has a three-stage selection process — CBT, Group Discussion, and Personal Interview — making it one of the few PSU exams that tests both academic preparation and soft skills. Getting the CBT rank is only half the battle.
HPCL 2026 Exam Pattern
The HPCL ET CBT has 170 questions to be solved in 150 minutes. Negative marking is 0.25 per wrong answer. The paper is divided into four sections:
| Section | Questions | Weightage |
|---|---|---|
| Technical / Domain | 85 | 50% |
| Quantitative Aptitude | 30 | 17.6% |
| Logical Reasoning | 30 | 17.6% |
| English Language | 25 | 14.7% |
Tip
Accuracy matters more than speed. Attempting 130 questions with 90% accuracy beats attempting 160 with 75% accuracy due to negative marking.
Branch-wise Technical Focus Areas
The technical section is where HPCL is won or lost. Here are the highest-weightage topics by branch:
- ▸Mechanical: Thermodynamics + Fluid Mechanics account for ~40% of technical questions. Steam turbines, refrigeration cycles, and Rankine cycle variations are HPCL favourites.
- ▸Electrical: Electrical Machines + Power Systems = ~45% weightage. Transformer OC/SC tests, induction motor torque-speed characteristics and power factor correction are frequently repeated.
- ▸Civil: Structural Analysis + RCC Design = ~40%. IS 456 limit state design and soil mechanics (bearing capacity, consolidation) carry heavy marks.
- ▸Chemical: Mass Transfer + Heat Transfer dominate. Process Control and Instrumentation carries significant marks unique to HPCL Chemical paper.
- ▸CS/IT: DSA + DBMS + Networks = ~40%. HPCL CS paper uniquely tests industrial automation, ERP systems and IT infrastructure in refinery context.
HPCL Cut-off Trends
Cut-offs vary significantly by branch. Mechanical typically has the highest cut-off due to the largest candidate pool. Chemical and CS/IT tend to have relatively lower cut-offs. In recent cycles, cut-offs for Mechanical have ranged from 65–72% of total marks, while Chemical has seen 58–65%.
The final merit list combines CBT score (70%) and interview performance (30%). A borderline CBT rank can be recovered with a strong GD and PI.
Group Discussion and Personal Interview
HPCL's GD topics are almost always energy-sector or policy related: crude oil pricing, renewable energy transition, LPG subsidy reform, India's energy security. Preparation should focus on understanding India's petroleum sector — refinery capacity, import dependence, and HPCL's specific business segments.
The Technical PI for HPCL goes deep into branch fundamentals. Expect questions on your B.Tech final year project, core subject derivations, and applied questions like 'how does a centrifugal pump cavitate and how do you prevent it.' HR PI typically covers situational questions and HPCL's role in India's energy landscape.

Preparation Strategy: 90-Day Plan
Days 1–30: Solidify two highest-weightage technical subjects for your branch. Do not spread thin across all subjects. One chapter per day, MCQ practice daily.
Days 31–60: Cover remaining technical subjects + start aptitude and reasoning. HPCL aptitude is moderate difficulty — DI, time-distance, percentage, and data sufficiency. Daily 20-question sessions are enough.
Days 61–90: Full-length mock tests every alternate day. Review wrong answers the next day. Identify your accuracy-speed pattern and adjust accordingly. Start GD topic reading in the final 3 weeks.
