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 the last time you had to troubleshoot a downed piece of automated production equipment with a PLC involved. What was the process from the moment you got the call to the machine running again?
whether the candidate has a real, structured troubleshooting method versus guessing under pressure
Describe a time you laid out and wired an entire relocated or rebuilt machine from scratch. What did that process look like from schematic to energizing it?
ability to handle full installation work, not just repair and maintenance
Tell me about a time you had to train or mentor an apprentice on something technical. How did you know they actually understood it and weren't just nodding along?
ability to transfer skill, not just possess it, since mentoring apprentices is part of the role
Tell me about a continuous improvement idea you brought to a maintenance team. What happened to it?
whether the candidate actively contributes to process improvement or just does assigned repairs
Technical
Tell me about your experience with Allen Bradley PLCs and ladder logic. What's the most complex program you've had to read or modify to diagnose a fault?
actual depth of PLC knowledge versus surface familiarity
What's your hands-on experience with DeviceNet networks, and have you had to diagnose a communication fault on one?
specific exposure to the named control network rather than general automation knowledge
Have you worked with Mazak CNC machinery or RFID-based tracking systems on a production line? Tell me about a specific issue you resolved on one of those.
whether the named equipment experience is real or just listed as familiar
How do you approach reading an unfamiliar electrical schematic on equipment you've never seen before, especially when there's no documentation for recent changes?
schematic literacy and adaptability when documentation is incomplete or outdated
What's your experience diagnosing and replacing electrical motors, and how do you decide whether to repair in place versus pull the motor?
practical judgment on motor maintenance decisions
Situational
Say a robot cell on the line goes down at 2 a.m. and you're the only electrician on shift. Nobody else is around to consult. How do you approach it?
comfort working independently on 3rd shift with no backup or supervision
You're working on a control circuit and the voltage jumps between 24V and 480V AC depending on the section. What precautions do you take before you even touch anything?
safety discipline and lockout/tagout habits across mixed voltage systems
Describe a situation where you disagreed with a production supervisor about whether a machine was safe to run. What did you do?
willingness to hold the safety line even under production pressure
How do you keep your documentation and paperwork current when you're moving fast between multiple breakdowns in a shift?
discipline around documentation despite the pace of a heavy manufacturing floor
