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.

Using concepts you studied in open-channel flow and irrigation engineering, explain how you would assess and improve the hydraulic efficiency of an existing earthen distributary that is suffering from seepage losses and silt deposition. What investigations, calculations, and remedial measures (e.g., lining, slope adjustment, control structures) would you propose as an Executive Engineer in the irrigation department?

Describe a recent full‑stack feature you implemented from scratch. How did you design the data model, choose the API structure, and integrate the front end with the back end? Walk through specific technical decisions you made and any trade‑offs you considered.

Describe in detail how you typically organize and architect a mid-sized React (or similar framework) codebase for a multi-page product (e.g., routing, state management, reusable components, and API integration). What trade-offs do you consider?
