Android Architecture and Patterns Questions

Comprehensive understanding of Android architecture patterns and pragmatic application of those patterns in production apps. Topics include MVVM MVI and clean architecture approaches, separation of concerns between UI view model and repository layers, unidirectional data flow, use cases and domain boundaries, dependency injection patterns and tools, state management using LiveData StateFlow or reactive streams, offline and caching strategies, testing approaches for each layer, and trade offs when choosing an architecture. Candidates should be able to design an architecture for a feature end to end justify module boundaries and explain how the chosen patterns improve maintainability testability and scalability.
