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 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?

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?

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?

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?

communication skills needed to bridge mechanical and electrical teams as stated in the posting

Technical

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.

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?

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.

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.

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?

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?

whether the preferred qualification is genuine hands-on exposure or just a term they've heard

Situational

If you got a sensor reading that looked wrong during a test, what would you check first before assuming the sensor itself is bad?

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?

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?

seriousness of commitment and logistical readiness for a relocation-required internship
