SJE-Rhombus Systems Engineer interview questions & guide 2026

The following questions reflect the core competencies required for a Systems Engineer at SJE-Rhombus. While specific technical tasks may vary, these patterns represent the areas where you will be most rigorously evaluated.

Technical and Domain Expertise

These questions test your foundational knowledge of electrical systems, control theory, and your ability to apply engineering principles to real-world scenarios.

• How do you approach the design of a control panel for a new pumping application?
• Can you describe your experience with PLC programming and troubleshooting?

Preparation for SJE-Rhombus requires a focus on both your technical depth and your ability to communicate complex ideas clearly. Approach your preparation as a professional review of your own engineering portfolio.

Role-related Knowledge – You must be prepared to discuss specific electrical and control components. Interviewers will look for your depth of understanding regarding circuit design, relay logic, and automation hardware. Be ready to explain the "why" behind your design choices, not just the "how."

Problem-solving Ability – We value engineers who think methodically. Whether you are dealing with a design flaw or a manufacturing constraint, demonstrate a structured approach: identify the issue, gather data, evaluate alternatives, and implement a solution.

Communication and Collaboration – As a Systems Engineer, you will interface with cross-functional teams. You must demonstrate that you can explain complex technical concepts to non-technical stakeholders and work effectively with team members across different departments to reach project goals.

The interview process at SJE-Rhombus is designed to gauge your technical proficiency and your fit within our engineering culture. You should expect a series of interactions that move from initial screening to in-depth technical discussions. The pace is professional and thorough, reflecting the high standards we maintain for our products.

Our philosophy centers on practical application. We want to see how you think through problems and how you apply your engineering knowledge to the specific challenges we face in the water and control industry. You will likely engage with both peers and leadership, providing you with a comprehensive view of the team dynamics.

The visual timeline above outlines the typical progression of our hiring process. Use this to structure your preparation, ensuring you have refreshed your knowledge of both theoretical concepts and your own past project experiences before your technical deep-dive rounds.

Electrical and Control Design

This area covers your ability to design robust and efficient systems. We look for candidates who understand the nuances of industrial electrical design and safety compliance.

Be ready to go over:

• Schematic Design – Your experience with CAD tools and your attention to detail regarding wiring diagrams.
• Component Selection – How you choose relays, controllers, and sensors based on project requirements.

As a Systems Engineer, your day-to-day work centers on the lifecycle of our control systems. You will translate customer needs into technical specifications and lead the design process for control panels. This involves constant collaboration with production teams to ensure that what you design can be efficiently built and reliably deployed.

You will also serve as a technical resource for internal teams. When issues arise in the field or during the manufacturing process, you are expected to provide clear, actionable guidance. Expect to manage multiple projects simultaneously, balancing new product development with the support of existing, high-performing systems.

A strong candidate for the Systems Engineer position at SJE-Rhombus brings a mix of hands-on technical skill and a proactive mindset. We look for individuals who are comfortable with the end-to-end engineering process.

• Must-have skills – Proficiency in electrical design software, deep understanding of PLC/control logic, and experience with industrial control components.
• Nice-to-have skills – Experience in the water/wastewater industry and familiarity with specialized communication protocols.
• Experience level – We offer roles ranging from entry-level (Engineer I) to senior positions (Senior Engineer), with compensation and expectations scaled accordingly.

Q: How much technical preparation should I do? A: You should be deeply familiar with the specific electrical and control projects listed on your resume. Be prepared to explain the technical hurdles you faced and how you overcame them.

Q: What differentiates successful candidates? A: Successful candidates show a balance of technical competence and a collaborative attitude. We look for engineers who are not only smart but also easy to work with and invested in the team's success.

Q: Is there a specific culture I should be aware of? A: SJE-Rhombus values reliability, safety, and innovation. We work in an environment where precision matters, so showing a disciplined, detail-oriented approach to your work is highly regarded.

• Structure your answers – When answering behavioral or technical scenario questions, use the STAR method (Situation, Task, Action, Result) to keep your responses concise and impactful.
• Know your resume – Be prepared to discuss any technical project in extreme detail; if it is on your resume, it is fair game for deep-dive questions.
• Ask thoughtful questions – Use your time with the interviewers to ask about the team’s current technical challenges or the company’s approach to new product development.

The Systems Engineer role at SJE-Rhombus offers a unique opportunity to shape the future of our control systems. By focusing your preparation on your technical design experience, your problem-solving process, and your ability to collaborate across teams, you will be well-positioned to succeed in the interview process.
