Sample Answer
(S) Our React SPA had minimal automated tests; regressions in core flows (login, checkout) were frequent, causing 2–3 hotfixes per month. (T) I was tasked with improving reliability without slowing the team down with an overly heavy testing process. (A) I started by identifying high-risk areas based on bug history and traffic, then introduced Jest and React Testing Library for unit/integration tests and Cypress for E2E. I created a testing strategy: unit tests for pure logic and components, integration tests for complex forms, and a lean E2E suite for the checkout and account flows. I set up GitHub Actions to run tests on every PR, with E2E smoke tests on main. To encourage adoption, I paired with teammates to write the first 20–30 tests and added coverage thresholds for new code. (R) Within two months, we increased frontend test coverage from ~10% to ~65% on critical modules, reduced production regressions in core flows by about 70%, and cut average hotfixes from 2–3 per month to roughly one per quarter. PR cycle time increased by only ~5–10%, which the team felt was acceptable given the stability gains.

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?
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.
