Sample Answer
On a previous ecommerce project, we started getting sporadic “ghost” cart issues: about 5–7% of users would see items disappear after refreshing the page. Frontend logs looked clean, and the API was returning 200s, so it wasn’t obvious. I started by reproducing it with a network throttler and multiple tabs, while tailing both browser logs and backend logs with correlation IDs. I noticed that under slower connections, the React app sometimes sent two rapid PATCH requests to the /cart endpoint. The backend used a non-atomic read-modify-write on a shared Redis key, so the second request occasionally overwrote the first with stale data. I paired with our backend engineer to introduce an optimistic locking mechanism plus idempotency keys on cart updates, and I also debounced the client-side updates. That dropped cart-related support tickets by ~90% within a week and improved checkout completion by about 3.5%.

In your resume you note improving or optimizing [a process, KPI, or metric]. What specific baseline metrics did you start from, what steps did you personally take, and how did you verify that the improvement was due to your changes rather than external factors?
On your resume you mention working on a cross-functional project (e.g., involving multiple teams or stakeholders). Describe a situation from that project where priorities conflicted—how did you navigate the trade-offs and what was the final outcome?
Walk me through a recent multi-channel digital marketing campaign you managed end-to-end. How did you set objectives, choose channels, allocate budget, and measure success?

Describe one such design in detail, including how you determined discharge, permissible velocity, section dimensions, and lining choice for Gujarat-type soil and climate conditions.
Based on your hydrology and irrigation engineering background, explain how you would estimate the irrigation water requirement for a kharif crop in a semi-arid region of Gujarat.
