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
Describe a situation where inventory levels at a site were badly out of line with targets. How did you find the root cause and what action funnel did you build?
structured problem-solving on inventory health, since that's a named metric they own
Tell me about a time you had to influence a cross-functional team, maybe manufacturing or demand planning, when you had no direct authority over them. How did you get them to move?
the influence-without-authority skill the posting calls out directly for leading SIOP meetings
Tell me about a time your supply plan and the site's actual production plan diverged. How did you catch it and get them realigned?
attention to the gap between planned and executed supply, a core accountability in this role
Give me an example of root-causing past-due demand at a site. What was the real cause versus what people assumed it was, and what countermeasure actually stuck?
rigor in distinguishing symptoms from root cause and follow-through on permanent fixes, not just firefighting
Technical
Walk me through how you would build an 18-month rolling supply plan starting from a demand plan that's given to you. Where do you start and what breaks first?
whether the candidate actually understands the mechanics of translating demand into a phased supply plan across long and short horizons
Tell me about a time you had to turn a rough-cut unit forecast into a SKU-level supply plan for short-range materials planning. What went wrong along the way?
hands-on depth with the specific long-range to short-range translation this job requires, not just familiarity with the term
How have you used Oracle or SAP settings to fix a recurring planning problem, rather than working around it manually every cycle?
real ERP fluency versus surface-level exposure, since the job explicitly wants someone who configures the system
Walk me through how you'd set up a dashboard in Power BI or Tableau to track supply plan accuracy and attainment across multiple sites. What would you actually put on it?
whether they can design useful metrics rather than just pull existing reports
What Lean tools have you actually applied to a planning or inventory process, and what changed as a result?
whether continuous improvement experience is concrete or just a resume keyword
Situational
A plant manager tells you the supply plan you've published isn't achievable with current capacity, but sales is counting on that volume. What do you do?
how they handle the constant tension between demand fulfillment and capacity reality without just deferring upward
You're running a plant-level SIOP supply meeting and a site flags a labor constraint that will blow past due demand out further. Talk me through how you handle that meeting.
ownership of the meeting cadence and ability to escalate and drive resolution rather than just document the problem
If a key supplier or internal site suddenly can't meet a committed volume and you have multiple customers competing for limited supply, how do you decide allocation?
judgment under constrained supply and ability to work cross-functionally on prioritization decisions
Tell me about the toughest working capital versus service level tradeoff you've had to make. How did you decide, and who did you have to convince?
understanding of the core business tension this role sits on top of and comfort making a defensible call
