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 project where you had to combine mechanical and electrical knowledge to solve a problem. What was your role and what did you actually build or fix?
What they are checking: whether the candidate has real cross-disciplinary experience versus purely coursework theory
Tell me about a time you had to design or set up a test to collect data on a physical system. What did you measure and how did you know your setup was giving you good data?
What they are checking: understanding of test design and data acquisition rigor
Describe a situation where you disagreed with an engineer or teammate about how to approach a design problem. How did you handle it?
What they are checking: ability to work respectfully across disciplines and experience levels without being passive
Tell me about a time you had to explain something technical to someone who didn't have your background. How did you adjust your explanation?
What they are checking: communication skills needed to bridge mechanical and electrical teams as stated in the posting
What would you do
If you got a sensor reading that looked wrong during a test, what would you check first before assuming the sensor itself is bad?
What they are checking: systematic troubleshooting instinct versus jumping to conclusions
Suppose you're asked to help improve an existing actuator product, but the engineer leading the project is unavailable for a week and you hit a roadblock. What do you do?
What they are checking: initiative and judgment about when to push forward versus wait, in an ambiguous internship setting
This role requires being full time on-site in Fond du Lac from May through August. What made you choose to apply here specifically, and how are you thinking about relocating for the summer?
What they are checking: seriousness of commitment and logistical readiness for a relocation-required internship
About the work
Walk me through how you would troubleshoot an actuator that's drawing more current than expected but still moving through its full range of motion.
What they are checking: structured diagnostic thinking across electrical and mechanical failure modes
What is the difference between a brushed and a brushless motor, and why might you choose one over the other for a marine drive actuator?
What they are checking: baseline knowledge of motor types required for the actual product line
Have you used MATLAB or Python to process test data? Describe a specific dataset you worked with and what you were trying to pull out of it.
What they are checking: concrete data-processing experience versus a resume line with no substance
Explain what a DFMEA is and walk me through how you'd identify a failure mode for a hydraulic actuator component.
What they are checking: real exposure to failure mode analysis methodology, not just familiarity with the acronym
What do you know about power electronics, like drivers or controllers, that would be relevant to running an electromechanical actuator?
What they are checking: depth of coursework or hands-on knowledge in power electronics specific to actuator control
Have you had any exposure to electrohydraulic or electromechanical actuators specifically? If so, what did you do with them?
What they are checking: whether the preferred qualification is genuine hands-on exposure or just a term they've heard
