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
Tell me about a coating or printing defect you traced to its root cause in a metal packaging operation.
What they are checking: Whether they have real hands-on process experience with coil coating or sheet printing.
Tell me about a continuous improvement project you led from start to finish. What were the results?
What they are checking: Whether they deliver measurable gains and can explain how they got them.
How do you document process settings so they're consistent across shifts?

What would you do

A customer complains about color variation between lots. How do you investigate?
What they are checking: Whether they can use measurement data and process records to find what changed between lots.
About the work
Walk me through the key variables in oven curing for coated metal sheet, and what happens when they drift.

How would you approach reducing waste on a sheet coating line?
What they are checking: Whether they can use data and continuous improvement methods to find and cut the biggest losses.
Print registration on sheets starts going off partway through a run. What do you look at?

What they are checking: Whether they plan trials and testing to protect food-contact performance and line efficiency.
How do you handle the environmental and safety side of running coating ovens and solvents?
What they are checking: Whether they consider emissions, ventilation and fire risk as part of process engineering.
What do you check during metal coil cutting to keep sheet quality right for coating and printing downstream?
What they are checking: Whether they understand how upstream sheet quality affects every later step.
