Sample Answer
On my last team, we standardized on the ELK stack for logs, Prometheus + Grafana for metrics, and Jaeger for distributed tracing across about 40 microservices. That stack heavily influenced how I designed endpoints and error handling. Every request gets a correlation ID injected at the edge and propagated through HTTP headers and Kafka messages. In handlers, I log in a structured way (JSON with service, endpoint, userId, requestId, latency, and key business fields), and I’m very deliberate about log levels: warnings for client mistakes, errors only for genuine server issues. That reduced noisy “error” logs by ~60%. For metrics, I expose RED metrics (rate, errors, duration) per endpoint and business KPIs, like signup conversion. When something spikes, tracing lets us see the slow span within seconds instead of digging through logs for hours, which cut mean time to resolution by roughly 30–40%.

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.
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.
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?
