Sample Answer
On my last project, I helped design auth for a customer portal used by about 40k monthly active users. We went with a stateless JWT-based approach. On login, the backend (Node/Express) issued a short-lived access token (15 minutes) and a refresh token (7 days). The refresh token was stored in an HTTP-only, Secure, SameSite=Lax cookie; the access token lived only in memory on the client to avoid XSS-related theft. On the React side, I wrapped the app in an AuthProvider that decoded the JWT, cached the user/roles, and used a PrivateRoute component to protect routes and redirect to /login when unauthenticated. Role-based checks were enforced both in the UI (e.g., hiding admin buttons) and, more importantly, in the API layer using middleware. Each route declared required permissions, and the middleware validated them against a roles-permissions table in Postgres. We also stored a token version per user so we could instantly revoke all refresh tokens on password reset or account compromise.

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?
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?
