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
Much of this work is a co-innovation program with customers. Tell me about building something with a customer while requirements were still moving.
What they are checking: Whether they can deliver in close partnership with customers when the target keeps changing.
Tell me about a time you had to learn a new platform fast to deliver a project.
What they are checking: Whether they can keep up with a fast-changing product portfolio.
What would you do
A customer's plant engineers are wary of letting new software near their production lines. How do you win their trust?
What they are checking: Whether they respect uptime concerns and can roll out changes safely.
About the work
Tell me about an application you built in Studio 5000 Logix Designer. How did you structure the code so others could maintain it?
What they are checking: Whether they write Logix code with structure and standards, not just code that works once.
What have you built with FactoryTalk Optix, and how does it compare to older HMI tools you have used?
What they are checking: Whether they have hands-on experience with the HMI and edge platform the posting names.
Walk me through how you would get machine data from a Logix controller into FactoryTalk DataMosaix and on to a cloud application.
What they are checking: Whether they understand the full edge-to-cloud data path across OT and IT layers.
How would you integrate production data with Plex MES and maintenance data with Fiix CMMS?
What they are checking: Whether they can connect enterprise systems to shop floor data in a useful way.
You design APIs and microservices for industrial data. What do you do differently because the data comes from a factory?
What they are checking: Whether they account for OT realities like intermittent connectivity, timestamps and high-frequency data.
How do you secure the connection between OT controllers and IT or cloud systems?
What they are checking: Whether they treat OT security as part of the design, since an exposed controller can cause physical harm.
How do you test an industrial application before it touches a running process?
What they are checking: Whether they use emulation and staged testing to protect live production.
