Insight into the EIL Mechanical Engineering Interview Experience

As I sat down for my interview with the Engineering Implementation Laboratories (EIL) through the Graduate Aptitude Test in Engineering (GATE) 2023, I was not only aiming for a challenging but also a fulfilling role in the construction department. This article shares my experience, the questions that were asked, and the journey I undertook to prepare for this critical interview.

Preparation and Context

I had undergone a Group Discussion (GD) round prior to the interview. My branch of study was Mechanical Engineering, and I was in the General Category. My GATE rank was AIR 189, and I was applying for a position in the construction post, specifically within EIL's 7 available roles for construction candidates and 9 others for various positions.

Interview Experience

The interview was stationed at EIL's head office in Delhi and lasted approximately 40 minutes. Here’s a detailed account of the interview process:

Introduction and Subject Inquiry

Upon my entry, I was met by a panel of four interviewers. They started by asking me to give a brief introduction about myself.

They then inquired about my favorite subjects that I had prepared for. I mentioned Fluid Mechanics, Thermodynamics, Powerplant RAC, and Heat Transfer. This was followed by a discussion on my professional background, particularly my internship experience in the automatic lubrication system at a coke plant.

Internship and Counter Questions

They delved into my internship, asking specific questions about lubricants, their types, and applications. I was asked about the different types of lubrication and their usage, the type of lubricant used in electric motors, its usage, and the effects of a lack of lubrication. In my excitement, I gave a slightly incorrect answer, but the interviewers were supportive, hinting at the correct response, which I then provided.

Windmill and Energy Conversion

The interviewers asked about windmills and the energy conversion process, which I answered confidently. They then moved on to more technical questions, covering fluid mechanics, heat transfer, thermodynamics, and various welding techniques, including soldering and brazing, with particular attention to welding defects and their detection.

About EIL and Reasons for Choosing Construction

They then inquired about EIL and what it does. I had prepared extensively for this, making sure to understand the company’s objectives and initiatives. I explained that being placed in LT Construction, I felt it would give me a better understanding of EIL's work, leading me to choose the construction department over other options.

Role of a Mechanical Engineer in Construction

There was a segment where I was asked about the role of a mechanical engineer in a construction department. I initially answered partially but was given a hint and asked the same question again, allowing me to provide a more comprehensive answer.

Personal and Professional Details

The interview extended to personal details such as my GATE rank, score, and why I chose EIL over other potential employers, including LT, NPCIL, and BARC. They also asked about IOCL and the reasons for my preference over EIL. I shared about my family background and the roles of my parents to provide a more holistic response.

Conclusion and Tips

The interview concluded with a positive note, and the results were communicated to me a week later, which included my selection. It was a rigorous and insightful interview that tested my knowledge, understanding of the technical aspects of my field, and my preparedness for a career at EIL.

Here are a few tips to help others prepare for similar interviews:

Thoroughly Prepare Your Internships and Projects: Ensure your internships and projects are closely aligned with EIL's operations and objectives. This will not only demonstrate your hands-on experience but also your readiness to contribute to the company's goals. Stay Calm and Confident: Even if you encounter challenging questions or mistakes, maintain your composure and seek clarification or hints from the interviewers. This shows your ability to think on your feet and learn from your mistakes. Know Your Strengths: Be prepared to discuss not only your technical knowledge but also your soft skills and personal qualities that make you a good fit for the role and company.

Preparation and clear communication can go a long way in making a positive impression. I am grateful for the opportunity to share my experience and hope it benefits those preparing for similar interviews.
