Sample Answer
I led a migration from ~40 Activities to single-Activity with Navigation for an app used by 50k MAUs. The main challenges were deep-link handling, shared ViewModel state, and preserving back-stack behaviour for analytics. I started with a pilot: migrated three feature activities to fragments, added a navigation graph, and introduced scoped ViewModels for feature-level state. We kept complex, isolated activities (camera workflow) for one sprint to avoid regressions, which cost an extra week but prevented user-facing bugs. Trade-offs: increased fragment lifecycle complexity vs. faster navigation animations and easier shared state. After migration we cut average navigation-related crash rate by 70% and reduced APK method count by 8%.

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.
