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
Why supply planning, and what part of your coursework or experience prepared you for it?
What they are checking: Whether they understand what planners do day to day and have a real reason for wanting it.
Tell me about a time your analysis turned out to be wrong. What did you learn?
What they are checking: Whether they own misses and adjust their method, since every forecast will be wrong to some degree.
Tell me about a problem you solved by noticing something in the numbers that others had missed.
What they are checking: Whether their attention to detail turns into useful findings rather than just careful data entry.
What would you do
How would you estimate inventory needs for a brand-new product with no sales history?
What they are checking: Whether they can borrow history from similar items and work with Merchandising to make a reasonable first call.
A buyer tells you a vendor is running two weeks late and customers are already ordering. What do you do?
What they are checking: Whether they act quickly with buyers and product managers to protect customer orders rather than just flagging the problem.
How would you explain a forecast to another department that doesn't know planning?
What they are checking: Whether they can communicate high-level plans in plain terms so other Uline departments can act on them.
About the work
Walk me through how you'd build a simple demand forecast for a product with two years of sales history.
What they are checking: Whether they can use trend and seasonality in a basic, sensible forecast rather than just averaging everything.
A product had one huge order from one customer last spring. How do you handle that when you forecast this spring?
What they are checking: Whether they know to separate one-time spikes from true demand so they don't overstock.
What's the cost of forecasting too high versus too low, and how would you think about that trade-off?
What they are checking: Whether they understand that both overstock and stockouts cost money and that the balance depends on the product.
How comfortable are you in Excel, and what's the most complex thing you've built in it?
What they are checking: Whether their number skills are hands-on enough for daily forecasting and inventory work.
