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
Walk me through an actuator you designed that had to bridge both electrical and mechanical systems. What was your role in each domain?
What they are checking: whether the candidate can genuinely work across electrical and mechanical boundaries rather than leaning on one discipline
Tell me about a time you led or participated in a DFMEA for a new or existing product. What failure modes surprised you once you dug in?
What they are checking: real hands-on experience with structured risk analysis versus just knowing the term
Tell me about a time you had to guide a technician through a test procedure that didn't go as planned. How did you handle it?
What they are checking: ability to direct and mentor technicians through detailed execution, a stated responsibility
Describe a project where you had to incorporate voice of customer input into a technical design. How did that change your engineering decisions?
What they are checking: whether the candidate can translate customer needs into systems engineering requirements
Tell me about a quality improvement project you contributed to. What was the measurable outcome?
What they are checking: genuine involvement in continuous improvement work versus passive exposure
What would you do
Say you're troubleshooting an actuator that fails intermittently in the field but passes every bench test. How would you approach isolating the cause?
What they are checking: structured troubleshooting logic across both electrical and mechanical failure paths
Tell me about a time procurement or quality raised a concern about your design partway through development. How did you resolve it?
What they are checking: cross-functional collaboration skill and willingness to adjust designs under real constraints
If you inherited an existing actuator product line with known wear or seal issues, how would you prioritize which problems to tackle first?
What they are checking: judgment in balancing legacy product maintenance against new development demands
How comfortable are you working in a fast-paced lab environment where design and testing happen almost simultaneously, and can you give an example?
What they are checking: fit with the iterative, hands-on pace described in the posting
About the work
How would you compare a hydraulic actuator solution to an electromechanical one for a marine drive application, and what factors push you toward one over the other?
What they are checking: depth of applied knowledge across the actuator technologies central to this role, not just textbook familiarity
Describe your experience with brushed and brushless motors. What's different about how you'd control and troubleshoot each?
What they are checking: specific working knowledge of the motor types called out as required skills
Tell me about a test you designed that used data acquisition to answer a real engineering question. What did you measure and why?
What they are checking: practical DAQ and test design competence, not just tool familiarity
Have you used a multi-function oscilloscope to diagnose a power electronics or sensor issue? Walk me through that situation.
What they are checking: hands-on instrumentation skill for electrical troubleshooting, a preferred but telling qualifier
What experience do you have with seal or wear component design or manufacturing, and how does that affect actuator reliability?
What they are checking: depth in a specific preferred skill tied directly to marine actuator durability
