Sample Answer
At my last company, our AWS bill jumped from about $180K to $260K in a quarter, with no matching revenue bump. I pulled the CUR data into Athena and used QuickSight to slice costs by service, tag, and environment. Two things popped: idle-but-sized-up EC2 in non-prod and unoptimized RDS and S3 usage. I proposed three changes: implement right-sizing with Compute Optimizer, enforce schedules on dev/test via Instance Scheduler and Lambda, and move infrequently accessed data to S3 IA/Glacier with a lifecycle policy. We also introduced mandatory cost-allocation tags and a weekly cost review with engineering leads. We rolled the changes out in stages over six weeks. Using Cost Explorer and a simple internal dashboard, we tracked savings by team. Within two months, EC2 spend dropped 35%, RDS 20%, and S3 18%, bringing the monthly bill down by roughly $70K while keeping performance SLAs intact.

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?
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?
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.
