Sample Answer
Situation: Our flagship app had a cold start time of 4.2 seconds, causing increased churn on low-end devices. Task: I was tasked to reduce startup time by at least 30% without sacrificing functionality. Action: I profiled startup using Android Studio CPU and Systrace, identified heavy synchronous IO and unnecessary app initializations in Application.onCreate. I refactored initialization to lazy loading, moved noncritical work to background using WorkManager and Coroutine Dispatchers.IO, replaced a heavy JSON parser with Moshi streaming, and enabled App Startup library for prioritized initialization. I also converted a large Bitmap decode path to use inSampleSize and Glide with placeholders. Result: Cold start dropped from 4.2s to 2.6s (38% improvement), ANR rate decreased by 42% over two weeks, and 30-day retention improved by 5% on affected cohorts. Metrics tracked via Firebase Performance and Crashlytics.
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?
