Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

About your past

Tell me about a part you redesigned to be cheaper or easier to build. What did you change?

What they are checking: Whether they practice design for manufacture and assembly, which this posting emphasizes.

Tell me about a time a design you released had a problem on the production floor. What happened?

What they are checking: Whether they own mistakes and work with manufacturing to fix them quickly.

What draws you to designing products for renewable energy, microgrids or data centers?

What they are checking: Whether they have real interest in the energy markets this team serves.

What would you do

An electrical engineer needs more space for components than your enclosure allows. How do you work it out?

What they are checking: Whether they collaborate across disciplines and find tradeoffs instead of defending their own part.

About the work

Walk me through how you'd design an enclosure for outdoor equipment like an EV charger or battery system.

What they are checking: Whether they consider ingress protection, corrosion, thermal management and structural loads together.

How do you approach thermal management in a power product with heat-generating electronics?

What they are checking: Whether they understand heat paths, airflow and cooling choices that keep equipment within limits.

How do you choose a material for a structural sheet metal part?

What they are checking: Whether they balance strength, cost, weight, corrosion and fabrication process when selecting materials.

What CAD and analysis tools have you used, and how do you use FEA to make a decision?

What they are checking: Whether they use simulation to inform design rather than as decoration.

How do you qualify a mechanical assembly before it goes into production?

What they are checking: Whether they plan verification testing like vibration, thermal and environmental tests.

How do you apply tolerance stack-ups and GD&T to make sure parts fit when built?

What they are checking: Whether they understand how tolerances add up and how to call them out clearly on drawings.
