Difficulty: easy
Interview Round: Technical Screen
## Question
You built a web app with **React** and **Firebase**.
Explain how a React frontend typically **reads/writes data** with Firebase, and how you would structure the app for:
- Real-time updates (subscriptions)
- One-time fetches and caching
- Authentication and authorization
- Calling server-side logic (e.g., Cloud Functions)
You may reference using either **Realtime Database** or **Firestore**, and optionally a client-side data layer (e.g., TanStack Query).
Quick Answer: This question evaluates understanding of frontend-backend data flow and integration with cloud-hosted databases, specifically concepts like real-time subscriptions, one-time fetches and caching, authentication and authorization, and invoking server-side logic within the Software Engineering Fundamentals domain.
