Combine two network sources using Coroutines and Flow
Tests your grasp of async data combination and state management. A good answer uses Flow.combine in a ViewModel, fed by a Repository, emitting a sealed class for UI state (Loading, Success, Error). A red flag is trying to combine state in the UI layer itself.
This question tests your practical knowledge of modern Android architecture, specifically handling concurrent async operations with Coroutines and Flow. A strong answer starts in the ViewModel using Flow.combine on two repository Flows, models UI state with a sealed class (Loading, Success, Error) emitted to a StateFlow, and handles errors gracefully. The main red flag is suggesting complex manual synchronization or trying to combine data streams directly within the UI layer, which violates separation of concerns.
