Sample Answer
I’d build a React front end with an `<input type="file" multiple>` wrapped in a drag-and-drop zone. On select, I validate type (MIME/extension whitelist: jpg/png/webp), size (e.g., max 5 MB), and count, then show client-side previews via `URL.createObjectURL`. Errors (wrong type/too large/network) are surfaced inline per file. Uploads use a signed-URL approach: the frontend requests a POST `/api/uploads/sign` (Node.js/Express or NestJS), then uploads directly to S3/GCS, avoiding backend payload bloat. The backend stores metadata (URL, ownerId, size, hash) in Postgres and triggers a thumbnail Lambda/Cloud Function using Sharp/Imagemagick to generate multiple sizes and store them under a CDN (CloudFront) path. I cap file size at the API gateway, scan uploads with a malware scanner (e.g., ClamAV or cloud service), enforce authZ (per-user access), and use caching + pagination on the dashboard to keep thumbnail loads under ~200 ms P95.

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?
