Sample Answer
On AWS, I designed an event‑driven order processing platform for an e‑commerce client that needed to handle Black Friday spikes of 10x traffic without pre‑provisioning hardware. I went with a hub‑and‑spoke VPC model: a shared services VPC with Transit Gateway, then app VPCs with private subnets, NAT gateways, and AWS WAF in front of Application Load Balancers. Compute was mostly ECS Fargate for stateless services, plus Lambda for lightweight enrichment. We used Aurora MySQL for transactional data and S3 + Glacier for long‑term order histories, with KMS‑backed encryption everywhere. Security integrated with IAM Identity Center, security groups locked to least privilege, and GuardDuty/CloudTrail for monitoring. We supported ~8x traffic growth while cutting infra costs ~35% versus their colo. If I redesigned it today, I’d use more serverless (Lambda + EventBridge + DynamoDB) for low‑churn services to reduce operational overhead and improve elasticity even further.

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?
