Sample Answer
We had an outage where latency spiked 5x for a critical service used by ~200k daily users. I led the initial triage with two SREs and noticed autoscaling groups were running wrong instance types after an ad-hoc manual change. I rolled back to the last known-good Terraform state within 18 minutes, shrinking latency back to normal and avoiding an estimated $30k/day revenue hit. Post-mortem, I added drift detection with periodic 'terraform plan' checks, enforced PR-only infra changes, and implemented CI gating that rejected manual console edits by reconciling on a 15-minute schedule. Over three months drift alerts fell to zero and emergency interventions dropped by 85%.

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.
