Sample Answer
I’d start by reproducing the problem reliably across devices: automate a scrolling test (Monkey/espresso loop) on low- and mid-range phones and reproduce with a large dataset (500+ items). I’d attach Android Studio Memory Profiler and LeakCanary to capture heap growth and GC churn. In one past job we found Glide requests held references after onBind; I added logging and used onViewRecycled to clear/cancel loads and call Glide.with(view).clear(). I also downsampled images, enabled bitmap pooling, and switched a few expensive transformations to server-side versions. After changes I ran 1,000-scroll iterations and saw OOMs drop from 4 per 100 runs to 0, and memory steady-state fall by ~60%. I added regression tests and a CI memory threshold so we don’t regress.

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?
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.
