FAQ
What do materials planner interviewers look for?
They look for MRP knowledge, inventory awareness, supplier follow-up, lead-time judgment, shortage handling, data accuracy, and production communication.
How is materials planning different from production planning?
Materials planning focuses on parts and supply availability. Production planning focuses more on schedule, capacity, and work order timing.
Should I mention safety stock?
Yes if relevant. Explain how you balance service, risk, lead time, and excess inventory rather than treating safety stock as a guess.
