Mobile Problem Solving and Constraints Questions

Ability to diagnose and solve engineering problems that arise from mobile specific constraints such as limited memory storage and battery variable network conditions and device fragmentation. Topics include memory efficient data structures lazy loading streaming and pagination image and media handling network resilience progressive enhancement offline first approaches and graceful degradation on low end devices. Candidates should be ready to walk through trade offs prioritize optimizations and propose validation strategies using metrics and instrumentation to verify improvements.
