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
Walk me through a time you designed a test to answer an engineering question that hadn't been answered before. What did you measure and why?
whether the candidate can structure a test from a vague question to a defensible plan, not just execute one handed to them
Tell me about the last time you had to translate a CFD or FEA request to another group. How did you make sure they were validating the right thing?
ability to specify simulation requests clearly rather than throwing a vague ask over the wall
Describe a time you had to change a hydrodynamic shape, like a fin or a housing, to meet a functional requirement. What forced the change and how did you know it worked?
hands-on experience with iterative shape optimization tied to a measurable requirement
Tell me about a report you wrote that changed a design decision. What made it convincing to the people who read it?
communication skill and whether their documentation actually drives engineering outcomes
What's your experience with boats or marine systems, and if you don't have direct experience, how have you gotten up to speed on a technical domain you didn't know well?
honesty about gaps and evidence of fast, self-directed learning since marine-specific background is preferred but not required
Technical
How would you set up an on-water test plan to compare gearcase loads in calm water versus rough water versus a hard turn?
real understanding of what varies mechanically across those operating conditions and how to isolate it in a test matrix
Explain how you'd use an IMU on a boat to develop a structural load target for a propeller. Walk me through the coordinate transformations you'd need.
actual working knowledge of Euler angles and rigid body transformations versus name-dropping the terms
Give me an example of a script or tool you built in Python or MATLAB to process test data. What problem was it solving and who else ended up using it?
whether their coding is purpose-built and reusable, not a one-off exercise
How would you build an FMEA for a new gearcase design? What failure modes would you prioritize first and why?
whether they understand FMEA as a prioritization tool rooted in actual failure risk, not paperwork
Situational
Say you're running an on-water boat test and the load cell data on the propulsor comes back noisy and inconsistent between runs. What do you do before you write it off as bad data?
practical instinct for troubleshooting instrumentation versus jumping to conclusions about the physics
Suppose your 1-D performance prediction model disagrees with test data by a meaningful margin. How do you decide whether the model is wrong, the test is wrong, or both are right and something else is going on?
judgment about reconciling simulation, model, and physical test data without just trusting whichever number is convenient
If a prototype structural test on a midsection component comes back marginal, close to the requirement but not clearly a pass, what do you do next?
comfort making a recommendation under ambiguity instead of deferring the decision entirely
You need a component-level structural test during the prototype phase, but the test lab and the design analysis group have different opinions on what needs to be measured. How do you resolve that?
cross-functional collaboration skill and ability to align competing technical priorities without escalating unnecessarily
