Patterson & Dewar Engineers Systems Engineer interview questions & guide 2026

The following questions reflect the technical and professional expectations for this role. While specific inquiries may vary based on your experience level, you should expect a consistent focus on your foundational knowledge of power systems and your ability to apply engineering principles to practical scenarios.

Technical and Domain Knowledge

These questions evaluate your grasp of fundamental power systems concepts, including circuit analysis, protection schemes, and grid operations.

• How would you explain the difference between load flow analysis and short circuit analysis?
• What are the primary factors to consider when designing a distribution protection scheme?

Preparation for Patterson & Dewar Engineers requires a dual focus on your technical toolkit and your ability to communicate complex engineering concepts clearly. Your interviewers are looking for a combination of academic rigor and an orientation toward practical, client-facing solutions.

Technical Competency – You must demonstrate a solid foundation in electrical engineering principles, specifically within power systems. Be prepared to discuss your experience with industry-standard modeling software and your understanding of power system physics.

Analytical Rigor – Interviewers will test your ability to break down complex systems into manageable components. Show them your work: explain your thought process when solving a technical problem rather than simply jumping to the final answer.

Communication and Professionalism – As a consultant, you will eventually interact with clients. You must be able to articulate technical findings to non-technical stakeholders, ensuring that your logic is clear, defensible, and aligned with project goals.

The interview process at Patterson & Dewar Engineers is designed to be thorough and reflective of the technical rigor required in the power engineering field. You should expect a progression that begins with an initial screening to gauge your background and interest, followed by one or more technical assessments where your core engineering knowledge is tested in depth.

The firm prioritizes a collaborative environment, so expect to interact with multiple members of the engineering team. The tone is professional and focused on your capacity to contribute to ongoing projects immediately. The pace is steady, reflecting the deliberate nature of infrastructure engineering work.

The visual timeline above illustrates the standard progression from initial contact through technical assessment. Use this to pace your preparation, ensuring you have refreshed your core technical concepts before the deeper, skill-based interviews occur.

Power Systems Fundamentals

This area is the cornerstone of your evaluation. You will be expected to demonstrate a high degree of proficiency in power system analysis, including load flow, fault analysis, and steady-state stability.

Be ready to go over:

• Per-unit systems – Understanding how to normalize values across different voltage levels.
• Protection coordination – The logic behind relay settings and circuit breaker operation.

As a Systems Engineer, your primary responsibility is to perform high-quality technical analysis for power system projects. You will spend a significant portion of your time utilizing specialized software to build, run, and interpret models that inform client decisions regarding grid stability, equipment upgrades, and system expansion.

Collaboration is central to the role. You will work closely with other engineers to peer-review designs, ensuring that all work meets both internal quality standards and external regulatory requirements. You will often act as an internal consultant for your team, providing the data-driven insights necessary to move complex infrastructure projects forward.

A successful candidate at Patterson & Dewar Engineers possesses a blend of academic achievement and practical application.

• Must-have skills: A degree in Electrical Engineering (with a focus on power systems), proficiency in circuit analysis, and a strong understanding of power system modeling principles.
• Nice-to-have skills: Prior experience with industry-standard power systems software (such as ETAP, SKM, or PSS/E), and exposure to utility-scale project work.
• Experience level: Roles range from entry-level, where foundational knowledge is paramount, to senior positions requiring a proven track record of project management and technical oversight.

Q: How much preparation time should I dedicate to the technical portion? A: Dedicate at least 1–2 weeks to review core power systems theory. Focus on the concepts you haven't used recently, as the interview will test your ability to apply these fundamentals on the fly.

Q: What differentiates top-tier candidates? A: Top candidates don't just know the "what"—they know the "why." Being able to explain the engineering rationale behind your technical decisions is what separates a good candidate from a great one.

Q: Is there a specific culture I should be aware of? A: Patterson & Dewar Engineers values a culture of technical integrity and teamwork. Show that you are a lifelong learner who is eager to contribute to the collective knowledge of the engineering department.

• Show your work: When answering technical questions, narrate your thought process. It is better to show a logical, step-by-step approach than to provide a quick, unverified answer.
• Know your resume: Be ready to discuss the specific technical challenges you encountered in any past projects or internships listed on your CV.
• Ask informed questions: Prepare questions about the types of projects the team is currently handling to show your genuine interest in their work.

The Systems Engineer position at Patterson & Dewar Engineers offers a unique opportunity to shape the future of power infrastructure. By focusing on your technical fundamentals, maintaining a methodical approach to problem-solving, and demonstrating a clear, professional communication style, you will position yourself as a strong contender for this role.
