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 class project or work experience where you had to analyze data to find a problem, and walk me through what you found.
What they are checking: whether the candidate can apply basic analytical thinking to a real situation, not just recite coursework
Can you describe a time you had to work independently on something with very little supervision or direction? How did you keep yourself on track?
What they are checking: readiness for a co-op environment where they'll be given projects and expected to self-manage
Tell me about a time a plan you were working on hit an unexpected obstacle. What did you do?
What they are checking: resilience and problem solving under real friction, since the posting explicitly calls out overcoming unforeseen obstacles
What made you choose to study supply chain, operations, or procurement, and what part of it interests you most?
What they are checking: genuine motivation and whether their academic focus lines up with the actual work
Tell me about a group project where people disagreed on the approach. How did you handle it?
What they are checking: collaboration skills in a plant environment where they'll work alongside experienced professionals
What would you do
Say you noticed a supplier was consistently sending more inventory than the production line was using. How would you go about figuring out whether that's a real problem and what to do about it?
What they are checking: basic grasp of pull systems and inventory logic, and whether they think before acting
Imagine you're supporting a new product introduction and the parts list keeps changing right up to launch. How would you keep the inventory plan accurate?
What they are checking: whether they can think through change management in a fast-moving, imperfect environment
If you found that the way material currently flows from receiving to the production line was wasteful, how would you go about proving that and getting someone to act on it?
What they are checking: understanding of waste elimination concepts and the ability to influence without authority, since co-ops have no direct reports
This role runs a fixed co-op term, either January through August or May through December 2027, working full time on-site in Fond du Lac. What questions do you have about that commitment, and is there anything about the schedule or relocation that would be hard for you?
What they are checking: logistical fit and honesty about ability to fully commit to the term
About the work
What do you understand a PFEP, or Plan For Every Part, database to be, and why would a plant like this rely on one?
What they are checking: whether they've done homework on core supply chain terminology used in manufacturing
Walk me through how comfortable you are in Excel. What's the most complex thing you've built or done in it, like a pivot table, VLOOKUP, or a model?
What they are checking: whether their stated Excel proficiency has any substance behind it
What's the difference between VMI and consignment inventory, as you understand it?
What they are checking: whether they actually know the inventory management concepts named in the posting or are just familiar with buzzwords
How would you go about forecasting demand for a part if you only had a few months of past sales data to look at?
What they are checking: basic reasoning about demand planning and comfort working with incomplete information
