Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
Behavioral
Tell me about a time you found an error in your own design during a review, after it had already gone out. What did you do next?
honesty and ownership when their own work is the source of the mistake
Tell me about a project where you had to coordinate closely with purchasing and suppliers to get the right components approved. What went wrong and how did you fix it?
cross-functional coordination skill and how they handle supply chain friction
Describe a time you had to work with contractors, consultants, and end users who all wanted different things on the same project. How did you keep the design moving?
ability to manage competing stakeholder demands without stalling delivery
Tell me about a time you had to learn a new technology or standard quickly to apply it to a project. What was it and how did you get up to speed?
self-directed learning ability, since the role explicitly expects them to track new technology on their own
Technical
Walk me through a low or medium voltage switchgear design you developed from customer spec to final drawings. What was the scope and what made it technically tricky?
whether the candidate has actually led a design end to end, not just contributed pieces of one
Tell me about a project where you had to design a control scheme for paralleling multiple generators with one or more utility sources. How did you approach the control logic?
depth of hands-on experience with the specific application this role centers on, not generic power systems knowledge
How do you handle grounding scheme design differently between a low voltage system and a medium voltage system?
whether their MV knowledge is real or they've only worked LV and are stretching the resume
Describe your process for building out AC and DC schematics and one-line diagrams for a project submittal. What do you check before it goes to the customer?
quality control habits and familiarity with the actual deliverables this job produces daily
What's your experience programming or integrating PLCs and HMIs into a switchgear control system, and what platforms have you actually worked with?
concrete platform experience versus surface-level familiarity with automation
How would you troubleshoot a fault in a load management or generator control scheme once it's already installed in the field, working with limited information from the site?
practical debugging skill under real-world constraints, not just design-desk competence
What do you know about Modbus and CANbus, and where have you had to make one of those protocols work correctly in a design?
whether communication protocol knowledge is applied experience or just something they read about
Situational
A customer's specification conflicts with what NEC or UL891 requires. How do you handle that conversation with them?
comfort acting as the technical face of the company and pushing back on a client without damaging the relationship
You're mid-project and priorities suddenly shift because another project needs urgent attention. How do you decide what gets your time?
how they actually triage under the deadline-driven, multi-project environment described in the posting
