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 time you found a defect that was hard to reproduce. How did you track it down and what did you do to document it so a developer could act on it?
rigor in defect isolation and quality of written communication with engineers
Describe a project where you had to switch between two very different testing efforts in a short period. How did you manage the context switch without dropping quality on either one?
adaptability across shifting priorities, which the posting flags explicitly
Tell me about a disagreement you had with a software engineer over whether something was really a bug or expected behavior. How did you resolve it?
communication skill and diplomacy when pushing back on engineering
Tell me about a time you worked in a very small team, maybe just two or three people, to hit a testing deadline. What was your role and what almost went wrong?
fit for the small-team collaborative structure described in the role
Technical
Walk me through how you'd design a test plan for a new engine control feature that touches embedded firmware, a Windows diagnostic tool, and a mobile app all at once.
whether the candidate can think across the full software stack rather than testing one layer in isolation
What CAN bus tools have you used, like CANalyzer or CANoe, and can you describe a specific case where you used one to diagnose a communication issue?
hands-on depth with the named tools versus surface familiarity
Have you built or maintained an automated test framework before? Tell me about the scope of it and what problems it actually solved for the team.
real automation experience versus buzzword familiarity, since it's listed as highly desirable not required
How comfortable are you reading or writing C, C#, or C++ to understand what a piece of embedded or desktop software is actually doing, even if you're not the one writing production code?
code literacy needed to troubleshoot software behavior without being a developer
What experience do you have with Azure DevOps or similar tools for tracking test cases, defects, and requirements traceability?
practical fluency with the specific tooling stack named in the posting
Do you have any background with marine systems, boating applications, or internal combustion engines, and how did that experience shape how you approach testing them?
domain knowledge that would shorten ramp-up time, even though it's only preferred
Situational
Say you're testing a helm controller and you see an intermittent fault that only shows up during real-world lake testing but never in the lab. How would you approach chasing that down?
ability to bridge simulated versus real-world testing and reason about environmental variables
If you were handed a vague set of requirements for a new feature and asked to build test cases against it, what would you do first?
initiative and ability to work independently with minimal supervision, as the posting emphasizes
How do you decide what to prioritize between regression testing, exploratory testing, and new feature validation when a release deadline is close?
judgment under schedule pressure and understanding of test strategy tradeoffs
