Sample Answer
(S) I joined a team where a key pricing calculator component, written in jQuery with inline scripts, was difficult to maintain and caused frequent bugs. It was responsible for ~30% of our conversion funnel. (T) I needed to refactor it into our React codebase, improve test coverage, and ensure no regressions in calculation logic. (A) I began by adding Jest and Cypress tests around the existing behavior, focusing on edge cases and high-value user flows. I documented current inputs/outputs using real production data samples. Then I extracted the core calculation logic into pure functions with unit tests and built a new React component around that logic. I used feature flags to ship the new version to 10% of traffic and monitored error logs and funnel metrics. I also paired with QA to run side-by-side comparisons. (R) We increased test coverage for that area from ~10% to 80%, reduced related bug tickets by about 40% over the next quarter, and cut the file size of the component by roughly 30%. Conversion through that step improved slightly (around 3%), and the code became much easier for others to extend.
