Sample Answer
(S) While working on a recommendation service, I initially wanted to rebuild it using a new tech stack for better scalability. (T) After discussing with the product manager, I realized the real business goal was to increase click-through on recommendations by at least 5% within the quarter, not to change the stack. (A) I shifted focus to quick, testable improvements: I added tracking around recommendation impressions and clicks, then implemented a simple rules-based boost for items with higher conversion history. I worked with product to A/B test three ranking strategies and surfaced metrics in a shared dashboard. Instead of rewriting the service, I only optimized some queries and added a small cache, which took 2 days. (R) The winning variant increased recommendation CTR by 9% and overall revenue per session by about 3.5%. We delivered this within three weeks, well within the quarter. The experience reinforced my habit of asking for the target metric first and validating whether a technical change directly contributes to that outcome before investing in larger refactors.
