Android System Design Interview Prep with Saurabh Arora

System design rounds decide senior Android offers, and most people walk in unprepared. In 60 minutes we do a realistic mock. Stuff like designing offline sync for a chat app, scaling an app's architecture, caching and data layer calls. Then I tear your approach apart and rebuild it with you: tradeoffs, the Android-specific constraints like process death, Doze mode and battery life, and how interviewers actually score the round.
