Sample Answer
I’d first confirm the issue in Chrome DevTools using Performance and Network tabs. I’d check initial page load, TTFB, DOMContentLoaded, and Largest Contentful Paint. If TTFB is >1s, I’d inspect the backend. If most time is spent on “Waiting (TTFB)”, I’d profile the API in tools like New Relic/Datadog, checking endpoint latency, throughput, and error rates. I’d then run slow query analysis on the DB (e.g., PostgreSQL pg_stat_statements) to catch full table scans, missing indexes, or N+1 queries, measuring query times and rows scanned. On the frontend, I’d audit bundle size using Webpack Bundle Analyzer, lighthouse, and coverage to remove unused JS/CSS, enable HTTP/2, gzip/brotli, and image optimization. I’d iterate until p95 load time is <2s on 4G and Core Web Vitals are green.

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?
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?
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.
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?
