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 time you had to test something without much documentation or a clear spec. How did you figure out what to check?
What they are checking: whether the candidate can work with the documentation-driven process here while still being resourceful when things are unclear
Tell me about a project where you had to switch gears quickly, maybe from one task to a completely different one, with little notice.
What they are checking: adaptability, since the role explicitly requires moving between very different testing projects
Describe a time you found a problem in someone else's code or design and had to explain it clearly without knowing the full history of the project.
What they are checking: communication skill and tact when reporting issues to engineers who own the code
Tell me about a time you had to document something in detail, maybe a lab report, a process, or test results, so someone else could follow it without you there.
What they are checking: documentation habits, since the role is explicitly documentation driven
What draws you to the marine industry or boating in general, if anything?
What they are checking: genuine interest and context for the domain, which helps with test case creativity even though it's not required
What would you do
Say you find a bug during exploratory testing that isn't reproducible every time. What do you do before reporting it to the software engineers?
What they are checking: rigor in documentation and communication when results are inconsistent, since flaky bugs are common in embedded and mobile testing
If you had to test an embedded controller both on a simulator and later on an actual vessel, what differences would you expect to run into?
What they are checking: understanding that simulated results don't always match real-world hardware behavior
If a software engineer pushed back on a bug you reported, saying it's not really an issue, how would you handle that conversation?
What they are checking: confidence and collaboration skills when defending test findings without being combative
If you were asked to help design a physical test fixture for validating hardware, how would you start thinking about what it needs to do?
What they are checking: willingness and ability to think beyond pure software into physical test setup, which the posting mentions as a possible task
About the work
Walk me through how you would write a test plan for a new feature on a mobile app that pairs with an engine control unit.
What they are checking: whether they understand how to structure test cases and think about integration between mobile software and embedded hardware
What's the difference between regression testing, exploratory testing, and integration testing, and when would you use each?
What they are checking: basic grasp of core testing vocabulary the job explicitly calls out
Have you written any test automation scripts, in Python or otherwise? Tell me about one and what it actually checked.
What they are checking: real hands-on automation experience versus classroom-only exposure to Python
What working knowledge do you have of C, C++, or C#? Give me an example of something you built or debugged using one of them.
What they are checking: depth of programming background beyond just listing languages on a resume
