Preparing for the NDPHC Internship isn’t just another item to check off your graduate to-do list. It’s a golden opportunity—a 12-month paid internship with Nigeria’s largest fleet of power plants. Imagine gaining hands-on experience working with real electrical and mechanical systems, while stepping directly into the heart of Nigeria’s rapidly growing energy sector.

But before you can claim this chance, there’s a hurdle you need to clear: the online aptitude test. Every year, thousands of hopeful engineering graduates take this test, and only the best make it through.

In this post, we’ll break down exactly what the test covers, why practicing with real past questions is a game-changer, and how our specially crafted NDPHC Internship Past Questions & Answers Pack can give you a head start. Plus, we’ve included 10 sample questions to get your preparation underway.

What is the NDPHC Internship Program?

The Niger Delta Power Holding Company (NDPHC) launched the internship in 2022 as part of its Corporate Social Responsibility initiative to build local engineering talent. The program offers:

• Duration: 12-month paid internship across NDPHC’s National Integrated Power Projects (NIPP) power plants

• Target Group: Nigerian engineering graduates (Electrical, Mechanical, Chemical, Mechatronics, or Computer Engineering) not earlier than 2017, aged between 18 and 26

• Selection Process: Online Aptitude Test → In-person Interview → Security and Medical Clearance

Why the Aptitude Test Matters

NDPHC uses a competitive, computer-based aptitude test to shortlist candidates. The test evaluates your ability to think critically, analyze technical data, and make sound decisions under time pressure. With thousands of applicants vying for a limited number of internship slots, only those who stand out in the test move on to the next stage.

Practicing with actual past questions is one of the smartest ways to prepare. It gives you familiarity with the test format, reduces anxiety, and helps you build confidence.
