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 during testing that others had missed. How did you catch it and what happened after?
attentiveness to detail and follow-through on problem containment, not just spotting issues
Describe a time you had to fabricate or assemble a piece of test equipment from a blueprint. What issues came up?
practical fabrication skill and comfort reading engineering drawings
Tell me about a continuous improvement project you were part of that actually reduced defects or errors. What was your specific role in it?
real contribution to root-cause and corrective action work versus passive involvement
With ten years in this kind of work, what's a mistake early in your career that changed how you approach testing today?
depth of experience and capacity for self-reflection rather than just years logged
Technical
Walk me through how you'd set up a test on a new generator prototype, from reading the test procedure to getting the equipment ready.
whether the candidate follows structured test procedures rather than winging setup based on memory
Tell me about your experience working in an ISO 17025 accredited lab, or a lab with a similarly strict scope of operations.
real familiarity with formal lab accreditation requirements versus general shop experience
What kinds of mechanical, electrical, and electronic measurement devices have you used day to day, and which ones are you least comfortable with?
breadth of hands-on instrument experience and honesty about gaps
How do you go about writing up a formal test report versus a quick informal note for the engineering team?
ability to adjust documentation style and rigor to the audience and purpose
What's your experience keeping test data and lab records in a database system, and how do you make sure that data stays accurate over time?
comfort with data administration and understanding why traceability matters in a lab
How familiar are you with 5S programs, and what does keeping a lab organized actually look like in your day-to-day work?
whether the candidate treats lab organization as a discipline or an afterthought
Situational
Say you're running an environmental test and the readings look off compared to what you'd expect. What do you do before reporting anything?
discipline around verifying instruments and isolating measurement error before assuming a product defect
A production line calls you because a unit is failing intermittently and they need it back running. Walk me through how you'd troubleshoot it.
structured troubleshooting approach under time pressure versus guesswork
If you noticed a bill of materials didn't match what was actually on the test bench, what would you do?
attention to detail and willingness to flag discrepancies rather than working around them
