Object-Oriented Programming for MAANG Interviews

A book-shaped table of contents for OOP: paradigm foundations, the four pillars, object relationships, SOLID/GRASP design principles, memory and runtime internals, GoF design patterns, language-specific OOP, and OOP at system scale — cross-linking existing pattern, concurrency, and low-level-design notes instead of duplicating them.

1 — Domain-Driven Design Basics

Examines Entities, Value Objects, Aggregates, Repositories, and Domain Services as DDD's core building blocks.

2 — OOP in Distributed Systems

Examines how object modeling changes once objects cross process boundaries — Microservices, Service Boundaries, DTOs, Contracts, and APIs.

3 — OOP and Concurrency

Examines how Shared State, Synchronization, Immutable Objects, and the Actor Model interact with object design.
