Grokking the Object Oriented Design Interview is a learning resource that provides code examples and documentation for object-oriented design patterns and system design concepts.
The repository extends a course on object-oriented design interviews by adding executable and pseudo-code implementations to demonstrate design principles. It covers multiple case studies with Python code examples showing how to structure classes, relationships, and system components. The material includes UML object diagrams and system overview diagrams to visualize design patterns and architectural relationships, with detailed documentation explaining the patterns and their interactions.
This resource suits developers preparing for system design interviews or those seeking to understand how design patterns apply in practice. It works best as a supplementary learning tool alongside formal study, since the code examples are intentionally simplified—most sections use placeholder implementations with None or pass statements rather than full working code. The repository covers eight or more case studies with varying levels of completeness; some sections are left empty for self-directed practice. The diagrams can be viewed through PlantUML tools, making the visual relationships between components accessible without special software.
The project maintains comprehensive documentation including detailed explanations of all diagrams, patterns, and relationships. The repository includes both OOP basics that are executable and higher-level design examples that serve as pseudocode. The codebase is organized around multiple case studies with consistent structure across examples.
