Sample Answer
At my last role, I built a real-time monitoring dashboard in React for about 600 internal users to track order processing across regions. We were streaming events over WebSockets at peaks of 2–3k messages per minute. I split the UI into a container layer with hooks for data fetching/subscriptions and presentational components for rendering. For state, I kept server state in React Query (caching, refetch intervals, retries) and local UI state (filters, column visibility, sort) in a lightweight Zustand store so different widgets could stay in sync. For side effects, I wrapped the WebSocket connection in a custom hook that handled (un)subscription and automatic reconnects, and exposed a simple `useOrdersStream()` interface. Performance-wise, I used `react-window` to virtualize large tables (we went from ~1.8s render to ~200ms) and memoized heavy cell renderers with `useMemo` and `memo`. I also batched incoming events into 250ms intervals to avoid React re-render storms while still feeling real-time to users.

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. Walk me through each step: from reference evapotranspiration estimation, crop coefficient selection, effective rainfall calculation, to arriving at canal discharge for a given command area.
In your civil engineering studies, what specific design coursework or project work did you complete related to irrigation channels or canals (e.g., design of lined/unlined canals, distributaries, minors)? 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.
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?
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?
