1.Walk me through a corrective action you owned from the customer complaint to closure.
Why they ask
This is the core of the job. They want to hear whether you find real root causes or write CAPAs that close on paper and come back a few months later.
How to answer
- Name the complaint and the containment you did first: sorting stock at the customer, in transit and on your own shelves.
- Explain how you got to root cause, including the theory you ruled out and why.
- Describe the fix and why it addressed the cause rather than adding another inspection step.
- Say how you checked effectiveness before closing it and what you told the customer along the way.
