What this question tests
Rapid root-cause diagnosis and response prioritization under an operational crisis with a clear cost driver.
How to approach it
- Confirm the 30% increase is real and recent, checking for a reporting change in how 'wrong order' is logged.
- Segment by cause category: picking errors in the warehouse, wrong item shipped by a vendor, or a system bug in order-to-fulfillment mapping.
- Segment by fulfillment center, product category, and time period to find where the increase concentrates, since a single node likely drove most of it.
- Check for a recent change: a new warehouse, a new SKU catalog update, a staffing change, or a vendor onboarding.
- Propose an immediate mitigation, like manual double-check on the affected SKUs or fulfillment center, while root-causing continues.
- Define success metrics: wrong-order rate by fulfillment center, tracked daily until it returns to baseline.
What a strong answer includes
- Prioritizes segmentation by fulfillment center and SKU category first, since a 30% jump is likely concentrated, not evenly distributed.
- Proposes an immediate stopgap (manual QA on flagged SKUs) alongside root-causing, reflecting urgency appropriate to the business impact.
- Gives an illustrative finding, e.g. the spike traced to a new fulfillment center with untrained staff, marked as an assumption.
- Distinguishes a data/labeling bug from a true operational failure, since the fix differs completely.
Common mistakes
- Jumping to a company-wide fix before isolating where the spike concentrates.
- Not proposing any immediate mitigation despite the urgency implied by 'immediately.'
Likely follow-up questions
- What immediate step would you take in the first 24 hours?
- How would you prevent this from recurring after the root cause is fixed?
