Sample Answer
I led backend work on a ride-sharing microservice in Go, PostgreSQL, Redis, and gRPC for a team of six; the service handled ~25k requests/min during peak. I owned API design, DB schema, and observability. After a release latency spiked 3x, I dug into traces via OpenTelemetry and found long tail latencies on a single geo-indexed query that hit a full sequential scan when a nullable column was present. I reproduced the issue with a 10M-row dataset, added index diagnostics, and changed the query to use a covering index along with prepared statements and connection pooling tweaks. Within a week p99 latency dropped from 1.8s to 220ms and CPU costs fell ~35%, keeping SLAs intact.

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?
