McDermott Software Engineer interview questions & guide 2026

The following questions are representative of the patterns reported by candidates. Note that while technical questions may be highly specific to your domain, the core focus remains on your ability to apply engineering principles to real-world problems.

Technical and Domain Knowledge

These questions test your understanding of fundamental engineering concepts and their practical application within the energy sector.

• Can you explain the units of viscosity and perform a mass balance?
• How would you determine the shear force diagram (SFD) and bending moment (BMD) for a uniform load?

Preparation at McDermott requires balancing deep technical knowledge with the ability to communicate your practical problem-solving approach.

Technical Proficiency – You must be comfortable explaining the "why" behind your technical decisions. Interviewers prioritize candidates who can demonstrate a solid grasp of core engineering principles rather than just memorized formulas.

Practical Application – McDermott values "hands-on" experience. Be prepared to explain how your academic or past work experience translates to the field or office environments typical of large-scale construction and energy projects.

Communication & Collaboration – You will often work in multi-disciplinary teams. Demonstrate your ability to simplify complex technical ideas and explain how you contribute to a collaborative environment.

Alignment with Industry Goals – Research McDermott’s current focus, particularly in energy transition and sustainability. Showing that you understand the company’s strategic direction will distinguish you from other candidates.

The hiring process at McDermott is structured to be thorough yet professional. While the specific number of rounds can vary by location and seniority, you should generally expect a screening process followed by one or more technical assessments and interviews with managers or department heads. The process is designed to evaluate your competence in a practical, real-world context, often involving discussions about your CV, past projects, and technical problem-solving capabilities.

This visual timeline illustrates the typical progression from initial screening to final panels. Use this to pace your preparation; focus on your technical foundations early, and prepare your "professional story" for the behavioral and manager-led discussions that occur later in the process.

Technical Judgment

This area evaluates your ability to apply engineering theory to real-world scenarios. Strong candidates show they can troubleshoot, analyze, and justify their design choices.

Be ready to go over:

• Fundamental physics and math applications in an industrial context.
• Specific industry standards relevant to the role (e.g., offshore structures, instrumentation).

As a Software Engineer at McDermott, your day-to-day work centers on bridging the gap between digital solutions and physical engineering outcomes. You are responsible for designing, developing, and maintaining software tools that enable the company to execute its massive energy projects. This includes collaborating with project managers to understand technical requirements, working with cross-functional engineering teams to integrate data, and ensuring that all software deliverables meet the high safety and performance standards of the oil and gas industry.

You will often find yourself acting as a translator between engineering needs and technical implementation. Whether you are automating repetitive tasks to reduce manual effort or building robust systems for complex asset management, your goal is to enhance the operational capability of the team. Expect a fast-paced environment where your work directly supports the success of offshore construction, fabrication, and energy transition projects.

A strong candidate for this role possesses a blend of technical expertise and a practical, "can-do" attitude.

• Must-have skills: A solid foundation in core engineering principles, proficiency in relevant technical software, and strong analytical skills.
• Experience level: A demonstrated ability to apply theoretical knowledge to real-world projects is essential. Whether you are a recent graduate or an experienced professional, show how you have handled concrete engineering challenges.
• Soft skills: Clear communication, the ability to work well in a team, and the confidence to ask questions when you do not know an answer.

Q: How long does the interview process typically take? The timeline varies, but it is generally a streamlined process. Expect it to span a few weeks from the initial screen to the final offer.

Q: What is the best way to prepare for the technical portion? Review your fundamental engineering concepts and be ready to discuss the projects listed on your CV in significant detail. The interviewers want to know that you truly understand the work you have done.

Q: What is the culture like at McDermott? The culture is generally professional, collaborative, and focused on practical, high-impact results. There is a strong emphasis on safety and engineering excellence.

Q: Are remote work or hybrid options available? This depends heavily on the specific team and location. It is best to clarify this during your initial recruiter screen.

• Own your CV: Be prepared to explain every line on your resume. If you list a skill, be ready to provide an example of how you have used it.
• Focus on the "Why": Don't just explain what you did; explain why you chose a specific approach over others.
• Be curious: Ask thoughtful questions about the team’s current projects or the company’s vision for the energy transition.
• Stay confident: Maintain a professional, confident demeanor, even when faced with challenging technical questions.

The Software Engineer role at McDermott is an exceptional opportunity to apply your technical skills to projects that shape the global energy landscape. Success in this role requires a balance of rigorous technical knowledge, practical problem-solving, and a commitment to the high standards of safety and excellence that define the company.
