Mobile System Design Building Blocks- Part 1
I started reading this book Mobile System Design by ByteByteGo. It emphasizes on understanding about key building blocks of a mobile system design before jumping into designing actual apps. Here’s the crux of building blocks!

Architecture- Common patterns, architecture layering, modularization and testing
Data Management- Data storage, networking, authentication, pagination and performance.

Most widely adopted approaches are:
- Clean Architecture which emphasizes UDF and Repository pattern
- MVC, MVVM and MVI
How I put it in interview-
