Sample Answer
In my previous role, we faced a recurring conversion drop on our checkout flow. I gathered transaction logs and session recordings to quantify the issue, isolating mobile users as the primary segment. Using SQL and Python, I hypothesized a UI change caused friction. By optimizing the mobile interface based on this data, we increased conversions by 12% within a month.
Common Mistakes to Avoid
- Focusing on intuition rather than data
