Stream a server-rendered shell, virtualise the dense views and draw high-density charts to canvas, keep server cache separate from UI and URL state, coalesce socket messages into one commit per frame, give every widget its own empty, error and stale states, and enforce a byte budget per pull request.
Evaluate the candidate's ability to reduce Android app size and optimise delivery using Dynamic Feature Modules, the Play Core Library, and reversed dependency injection structures. Use this MOBILE answer to show the decision, trade-off, and evidence rather than a memorised definition.
Assess the candidate's ability to migrate a large-scale iOS application to a modular architecture using Tuist, managing dependency graphs, enforcing architectural boundaries, and optimising build times. Use this MOBILE answer to show the decision, trade-off, and evidence rather than a memorised definition.
Evaluate the candidate's understanding of offline-first principles, background processing using Android's WorkManager, conflict resolution strategies, and battery optimization techniques. Use this MOBILE answer to show the decision, trade-off, and evidence rather than a memorised definition.
Assess the candidate's understanding of the React Native architecture, bridge performance limitations, profiling techniques, and modern solutions like JSI and the New Architecture. Use this MOBILE answer to show the decision, trade-off, and evidence rather than a memorised definition. It also connects cross platform to the point an interviewer is testing.
Assess candidate's ability to architect fault-tolerant micro-frontends, manage distributed dependencies, and implement robust error handling in a Module Federation setup.
Cache hashed assets for a year and never cache the entry document, retain several previous builds so a stale tab can still fetch its chunks, and treat a failed dynamic import as the signal to prompt a reload rather than as an error to swallow.
