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 a machine went down on the floor and you had to figure out what was wrong. What was the actual problem and how did you find it?

real hands-on troubleshooting experience versus theoretical knowledge

Describe a preventive or predictive maintenance procedure you built from scratch. How did you decide what to include and how did you know it was working?

ownership of maintenance strategy versus just following existing procedures

Give me an example of a project you led on the floor, even an informal one. What was your role, and what would you do differently now?

actual project leadership experience since the posting explicitly asks for it despite no direct reports

Tell me about a time you wrote an SOP or maintenance documentation that someone else later used. What made it useful or where did it fall short?

clarity of documentation and awareness of how others will use it

Tell me about a time you had to learn a new technology fast because the job demanded it. What did you do and how long did it take before you were productive with it?

genuine adaptability given how many different tools and platforms this role touches

Technical

Say a work cell with an Allen Bradley PLC and an HMI throws an intermittent fault that only shows up under load. How would you go about isolating the cause?

systematic diagnostic approach on the exact PLC platform they use

How comfortable are you moving between Allen Bradley and Siemens platforms, and can you give an example where you had to work in both on the same project?

actual breadth across the two named PLC families, not just familiarity with one

Tell me about your experience with CNC controls, Siemens or Fanuc specifically. What kind of programming or troubleshooting have you done on them?

depth of CNC controls exposure since it's called out as a plus but tested directly

Have you built or maintained anything in Ignition SCADA? What did it connect to, and did you use SQL or Python anywhere in that work?

specific hands-on depth with the exact SCADA stack and scripting tools named in the posting

Tell me about a time you had to read or modify a controls print in AutoCAD to solve a real problem on the floor.

ability to translate documentation into physical troubleshooting or modification

What do you know about industrial network setups like Ethernet or DeviceNet, and have you had to troubleshoot a network issue that was actually a controls problem in disguise?

awareness that many controls failures are really network issues, and comfort diagnosing across that boundary

Situational

If a robot cell integrated with a vision system starts misreading parts intermittently, where do you start looking first?

understanding of how vision systems, robots, and RFID components interact and fail together

Two departments disagree about how a new automation solution should be designed and you're stuck in the middle. How do you handle that?

ability to work cross-functionally and influence design decisions without formal authority

How do you use data from the floor, like downtime logs or sensor data, to decide what to fix first?

whether analytics gets applied practically to prioritize work, not just collected
