OHPC Non-Executive Trainee 2025 – 125 Vacancies

Preparing for this exam becomes easier when you understand what OHPC expects from a trainee. The CBT isn’t about memorising thousands of facts; it is designed to test whether a candidate can learn quickly, follow safety standards, and work confidently inside a power unit. So your preparation strategy should focus on clarity, accuracy and speed—not cramming.

Below is a practical, step-by-step approach created specifically for this recruitment based on the exam pattern in the notification.

Build Concept Strength for the Technical Section

For most posts, technical questions form the largest part of the CBT. Don’t try to “learn everything.” Instead, revise what OHPC practically needs on the job:

• Electrical trainees should focus on wiring systems, earthing, measuring instruments, transformers, circuit protection, motors and troubleshooting basics.

• Mechanical trainees must stay strong in machine tools, fitting practices, safety rules, pumps, bearings, welding joints, and workshop calculations.

• Welder trainees should know welding types, defects, gas cutting, electrodes, safety and joint inspection.

• Crane operator trainees must revise lifting capacity, load charts, OHC safety, signalling and emergency handling.

• Store keeper trainees should focus on store records, stock handling, billing entries, material issue and inventory basics.

One smart way to prepare is to recall real workshop or training experiences. The exam often asks “what is practical” instead of highly theoretical questions.

Short and Accurate Attempts in the General Aptitude Section

This part has only 40 questions but can change the merit list because of negative marking. Accuracy matters more than attempting everything.
Focus on:

• Simple arithmetic, percentages, averages, unit conversions, ratio and time-work

• Clear reasoning questions like patterns, directions, odd one out, coding-decoding

• Basic English grammar, comprehension and error spotting

• Everyday current developments, safety rules, electricity basics and general awareness

If a question looks time-consuming, skip and return later. Many toppers clear exams not by answering all questions, but by avoiding wrong ones.

Keep Notes for “Frequently Asked Practical Questions”

This exam is from a power corporation, so well-prepared candidates revise:

• Why earthing is important

• What happens when a phase is missing

• Why a bearing heats up

• Difference between AC and DC machines

• Safety symbols and colours

• Lock-out, tag-out rules

• Welding defects and how to fix them

These are small topics but score easy marks.

Practice with a 2-Hour Timer

Since the CBT lasts 120 minutes for 120 questions, candidates often lose time switching between sections. Practice solving mixed questions to build rhythm. Within the first 60 minutes, aim to complete the parts you are strongest in, then move to tricky ones.

Read Instructions Carefully During Exam

OHPC clearly mentions negative marking. Many students lose marks by guessing. Every wrong answer brings a penalty, so mark only when you are confident. Smart accuracy always beats random attempts.

Prepare Documents Early

Many candidates qualify the exam but cannot clear document verification because of missing certificates or wrong file sizes. Keep digital scans of all certificates early, especially:

• ITI certificate

• Marksheets

• Odia language proof

• Trade experience certificates

• Workman-C permit for Crane Operator roles

• Valid caste or PWD certificate if claiming reservation

This reduces stress after the result.

Maintain a Calm and Safe Approach

Jobs in power corporations require stability, discipline and attention to detail. If you prepare with a calm mind, follow a timetable, and revise small topics daily, your score will automatically improve. Even 2–3 focused hours per day are enough when done consistently.
