Likely interview questions for this role

About your past
Tell me about a scheduling problem you solved that others thought couldn't be solved.
What they are checking: Depth of experience with complex scheduling and creative problem-solving under real constraints.
How do you work with logistics so that what you produce actually ships on time?
What they are checking: Seeing the schedule through to delivery instead of stopping at production completion.
Tell me about a continuous improvement initiative you led in planning. How did you measure it?
What they are checking: Leadership of improvement work, which the senior title and posting both expect.
What would you do
Sales calls with a rush order for a key customer that will bump three other orders. What do you do?
What they are checking: Making trade-offs visible to commercial and operations so the right people decide, rather than quietly reshuffling.
A furnace goes down for six hours. How do you rebuild the schedule and who do you tell?
What they are checking: Calm recovery planning and clear communication to logistics, sales and the floor after an unplanned outage.
How do you handle a production supervisor who keeps running orders out of sequence?
What they are checking: Addressing schedule discipline respectfully while understanding why the supervisor deviates.
About the work
Walk me through how you build a daily production schedule that balances customer demand, inventory and capacity.
What they are checking: Whether they have a repeatable method for the core of the job rather than reacting to whoever calls loudest.
In a continuous casting operation, changeovers between bar sizes and grades cost time. How do you sequence work to limit them?
What they are checking: Understanding of how sequencing drives efficiency in a continuous cast iron bar process like Woodstock's.
How do you decide how much finished inventory to hold for repeat customers?
What they are checking: Judgment on make-to-stock versus make-to-order and the cost of carrying iron bar inventory.
What ERP or planning systems have you used, and how much do you trust what they recommend?
What they are checking: Systems skill paired with healthy skepticism about bad data and default settings.
