Comprehensive Model Answer
Verified Solution
Most of the applications has several top-level directories as below:
- Components: Used for _dumb_ components unaware of Redux.
- Containers: Used for _smart_ components connected to Redux.
- Actions: Used for all action creators, where file names correspond to part of the app.
- Reducers: Used for all reducers, where files name correspond to state key.
- Store: Used for store initialization.
This structure works well for small and medium size apps.
Candidate Response Strategy & Interview Tips
- Start with a concise one-sentence summary: Deliver a direct, confident answer first before expanding into nuances.
- Demonstrate real-world trade-offs: Discuss where this approach excels and when you would avoid it in production systems.
- Discuss complexity & edge cases: Proactively explain time/space complexity or boundary conditions (null values, scale limits).
- Prepare for interviewer follow-ups: Technical hiring panels frequently probe deeper into concurrency, backward compatibility, or alternative libraries.
