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 class or team project where you had to design something under real constraints.
What they are checking: How they handle tradeoffs and teamwork before they have industry experience.
Tell me about a time you had to explain a technical idea in writing to someone who wasn't an engineer.
What they are checking: Clear, short writing, which the posting asks for specifically.
Tell me about a mistake you made on a technical project. How did you catch and fix it?
What they are checking: Honesty and learning from errors, which matters when interns touch production drawings.
What would you do
An engineer asks you to change a part on the BOM, but you're not sure it fits the rest of the assembly. What do you do?
What they are checking: Whether they check and ask before making changes that flow into manufacturing.
How would you balance 15 to 20 hours a week here with a full engineering course load?
What they are checking: Reliability during the school year, which the posting requires.
What would you do if you finished an assignment early and your supervisor was in meetings all day?
What they are checking: Initiative and judgment about useful next steps without direction.
About the work
What's a part or assembly you've modeled in Pro-E, Creo, SolidWorks or AutoCAD? Walk me through how you built it.
What they are checking: Real CAD experience, since interns here create models, drawings and templates from day one.
What is a tolerance stack-up, and why would one matter for a transfer switch enclosure?
What they are checking: Whether they grasp how small variations add up and affect fit and assembly.
What do you know about what a transfer switch does in a home standby system?
What they are checking: Curiosity about the product they would be designing for, not just the title.
How have you used Excel for engineering work, like tracking data or calculations?
What they are checking: Practical spreadsheet skill that supports analysis and BOM work.
