Sample Answer
At my last company, I had a classic tension between security, finance, and the product team for a new customer analytics platform on AWS. Security wanted everything private with no public endpoints, finance pushed for the absolute lowest cost, and product needed sub‑200ms responses for ~15k concurrent users. Instead of debating at a high level, I quantified the tradeoffs. I built three lightweight reference architectures in a week: one “secure-first,” one “cost-first,” and one “balanced,” and modeled expected costs and latency using load test data from our on‑prem system. We reviewed them in a joint workshop, walking through concrete numbers: for example, PrivateLink everywhere drove security risk down but added ~22% to monthly costs. We aligned on a hybrid design: private subnets with an ALB in public subnets, AWS WAF, and regional edge caching. That kept p95 latency under 180ms, cut projected infra spend by ~18% vs the secure‑only option, and passed internal security review on the first round.

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?
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.
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?
