Before you speak the answer, walk the interviewer through these steps:
- 1Server data goes in
a cache like React Query with keys per widget.
- 2UI chrome like sidebar
open stays local or in a small store.
- 3I avoid one giant
Redux dump of API responses because cache invalidation and background refetch are already solved by query libraries.
- 4Give an example
One tiny concrete case you can say aloud.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.
EXAMPLE — See it in action
Here's a short line you can speak, broken into clear beats:
Note: Adapt this scaffold to your own project — keep it under 60–90 seconds.
Key takeaway
Server data goes in a cache like React Query with keys per widget. UI chrome like sidebar open stays local or in a small store.
