Patterson & Dewar Engineers Software Engineer interview questions & guide 2026

The following questions reflect the core competencies required for engineering roles at Patterson & Dewar Engineers. Use these to understand the patterns of inquiry rather than as a rigid list to memorize.

Technical Competency and Domain Knowledge

These questions test your ability to apply software principles to electrical and physical engineering challenges.

• Can you describe your experience with software tools used in electrical design or substation layout?
• How do you ensure the accuracy and reliability of the software tools you develop?

Preparation at Patterson & Dewar Engineers requires a balance of technical depth and industry context. You should focus on demonstrating that you understand the specific constraints of the energy sector.

Technical Proficiency – You must demonstrate a solid grasp of the programming languages and software tools listed in your background. Expect to explain not just how you write code, but why you chose a specific architecture or method to solve an engineering-related problem.

Domain Adaptability – Even if your background is purely in software, you must show a willingness to learn the language of electrical and transmission line engineering. Interviewers want to see that you can communicate effectively with stakeholders who view the world through an engineering lens.

Attention to Detail – In the power industry, errors can have significant real-world consequences. Your interviewers will look for evidence that you are methodical, thorough in your testing, and disciplined in your documentation.

The interview process at Patterson & Dewar Engineers is designed to evaluate both your technical problem-solving capabilities and your ability to fit into a collaborative, engineering-focused culture. You can typically expect a series of discussions ranging from initial screenings with recruiters or hiring managers to deeper technical conversations with subject matter experts.

The pace is professional and deliberate, reflecting the high-stakes nature of the utility and infrastructure projects the firm manages. You should expect the process to be highly structured, focusing on your past experiences, your technical methodology, and your ability to collaborate with non-software colleagues.

This visual timeline illustrates the typical progression from initial contact through the final evaluation stages. Use this to pace your study and ensure you have designated time to revisit your past project documentation before the later-stage technical interviews.

Engineering-Software Integration

This area explores your ability to apply software logic to physical infrastructure. Strong candidates are those who can explain how their software creates value for physical engineers.

• Data Handling – Understanding how to manage large datasets related to transmission lines or substation components.
• Workflow Automation – Identifying repetitive manual tasks in engineering and building scripts or applications to automate them.
• Accuracy Standards – Discussing how you incorporate validation and verification into your development cycle.

As a Software Engineer at Patterson & Dewar Engineers, your primary responsibility is to develop and maintain the digital tools that empower our engineering teams. You will work closely with Substation Physical Engineers and Transmission Line Design Engineers to identify bottlenecks in their design processes.

You will likely be tasked with building custom applications, managing databases, and automating data processing tasks that support large-scale utility projects. Success in this role requires not only coding expertise but also a genuine interest in the power and utility space, as your software will be used to facilitate critical infrastructure development.

A competitive candidate for this role possesses a blend of strong software fundamentals and a high aptitude for learning complex engineering systems.

• Must-have skills:

  • Proficiency in core programming languages relevant to the team’s current tech stack.
  • Demonstrated ability to solve complex, logic-heavy problems.
  • Strong verbal and written communication skills for cross-functional collaboration.
  • A methodical approach to debugging and testing.

• Nice-to-have skills:

  • Prior experience or coursework in electrical engineering, power systems, or related fields.
  • Familiarity with CAD software or engineering modeling tools.
  • Experience in an industry where safety and regulatory compliance are critical.

Q: How long does the interview process typically take? A: While timelines vary by location and team, most candidates move through the process in a few weeks. We recommend maintaining consistent communication with your recruiter to stay updated on your status.

Q: Is industry experience in utilities required? A: While beneficial, it is not always a strict requirement. We value strong software fundamentals and a demonstrated ability to learn new, complex domains quickly.

Q: Will I be tested on electrical engineering theory? A: You will not be expected to be an electrical engineer, but you should be prepared to discuss how your software interacts with engineering data and why that data is important to the project.

Q: What is the culture like at the firm? A: Patterson & Dewar Engineers prides itself on a culture of technical excellence, precision, and collaboration. We look for individuals who are intellectually curious and take pride in the tangible impact of their work on public infrastructure.

• Contextualize your experience: When describing past projects, highlight the "engineering" impact—did your code save hours of manual calculation? Did it prevent a design error?
• Prepare your stories: Use the STAR method (Situation, Task, Action, Result) to keep your behavioral answers concise and impactful.
• Ask meaningful questions: Use your time at the end of the interview to ask about the team’s upcoming technical challenges or how they balance software development with project-based consulting.
• Be ready for technical depth: Even if the interview feels conversational, be prepared to dive deep into the architecture of your past projects.

The Software Engineer position at Patterson & Dewar Engineers offers a unique opportunity to apply your technical skills to the foundational infrastructure of the power grid. By focusing on your ability to integrate software with engineering workflows and demonstrating a clear, methodical approach to problem-solving, you will be well-positioned to succeed in your interviews.
