Get ready to dive into the object-oriented design of an Online Gaming Platform, inspired by systems like Steam or Epic Games. This interview experience focuses on evaluating your low-level design skills in modeling complex digital ecosystems that blend commerce, entertainment, and social networking. You’ll need to carefully think through scalability, concurrency, and security challenges.

What You'll Practice:

• Translating business requirements into detailed system requirements.
• Designing scalable and extensible architectures for digital content distribution.
• Applying solid OOP principles such as abstraction and polymorphism to real-world gaming features.
• Exploring relevant design patterns like Observer (for notifications) and Strategy (for matchmaking).
• Visualizing your design through UML diagrams, highlighting relationships among players, games, publishers, and platform services.

By the end of this interview, you’ll be well-prepared to handle design challenges that combine e-commerce, digital rights management, and real-time social interaction—skills highly relevant to modern large-scale platforms.
