Sample Answer
Situation: Team relied heavily on RxJava2, with complex disposables and memory leaks. Task: Evaluate and migrate to Kotlin Coroutines to simplify async code. Action: I piloted Coroutines in a small feature, demonstrating structured concurrency with CoroutineScope and SupervisorJob, and replaced Observable chains with suspend functions and Flow for streams. Created migration guides, automated lint checks to avoid mixing paradigms, and offered two training sessions. For interoperability, I used kotlinx-coroutines-rx2 adapters where incremental migration was necessary. During migration, we added unit tests for suspend functions and used CoroutineTestRule for deterministic testing. Result: Code readability increased, average function complexity decreased by 27%, memory leaks related to disposables dropped by 90%, and average bug turnaround time for async issues improved by 40%. The team completed migration over three sprints with minimal regressions.
Walk me through a recent multi-channel digital marketing campaign you managed end-to-end. How did you set objectives, choose channels, allocate budget, and measure success?
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.
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?
