Behavioral
Tell me about a time you found a failure mode on a product that wasn't obvious at first. How did you track it down?
root cause troubleshooting skill and patience with ambiguous failures
Have you used 8D, 5 Why, or PDCA on a real problem? Tell me about one and what the actual root cause turned out to be.
whether root cause methodology is a practiced skill or just a term they know
Tell me about a time you wrote or updated a test procedure or troubleshooting guide for someone else to use.
ability to document knowledge clearly enough that another technician can follow it
Describe a time you had to train a coworker on a work instruction or standard work. What made it stick for them?
teaching ability, since the role explicitly requires training other employees
What's your experience with 5S, and can you give me an example of how you kept your test station organized under a busy production schedule?
whether workplace organization habits are genuine or just something they say they value
Tell me about a time your test results or a process suggestion actually changed how something was done on the line.
initiative and willingness to contribute to continuous improvement, not just execute instructions
Technical
Walk me through how you'd perform a Hipot test on a unit up to 10KV, start to finish, including the safety steps you take before you even power it up.
whether the candidate actually knows the procedure and treats high-voltage safety as automatic, not an afterthought
Tell me about the medium voltage or high voltage testing you've done before, and which specific tests you're most comfortable running, like Doble, resistance, DGA, or CT test.
real hands-on exposure to the exact test types this job requires versus general electrical background
Have you worked in SAP or a similar ERP system like Oracle or JD Edwards? What did you use it for day to day?
comfort with the recordkeeping systems the role expects them to use
What's your understanding of NFPA 70E and why it matters for the work you'd be doing here?
baseline electrical safety knowledge required before they're allowed to work on medium voltage equipment
Situational
Say you're reading a schematic and the test result doesn't match what the drawing says should happen. What do you do next?
ability to interpret drawings correctly and troubleshoot logically rather than guessing or skipping the discrepancy
How do you decide whether a repair is something you handle at your workstation versus something you need to send to another resource?
judgment about scope of authority and knowing when a fix is beyond a minor repair
You're testing under takt time pressure and you hit a unit that's failing intermittently. How do you balance staying on schedule with actually solving the problem?
how the candidate handles production pressure without cutting corners on quality
If you noticed a piece of test equipment was drifting out of calibration or acting unreliable, what would you do before it caused bad data on the floor?
