Step into the challenge of designing a GitHub-like Version Control System, a cornerstone tool for modern software engineering teams worldwide. This interview case study evaluates your ability to break down complex collaboration workflows, capture essential system entities, and craft a scalable object-oriented design. You’ll grapple with concepts like repositories, branching, commits, and pull requests, while addressing concurrency, permissions, and collaboration patterns in a real-world setting.

What You'll Practice:

• Translating vague collaboration needs into precise system requirements.
• Modeling repositories, branches, commits, and pull requests with clean object-oriented principles.
• Handling concurrency and conflict resolution during merges and simultaneous updates.
• Applying design patterns that simplify workflow management and ensure maintainability.
• Presenting your design visually with UML diagrams that demonstrate relationships and flows.

By the end of this interview, you will sharpen your ability to reason about distributed collaboration systems, defend architectural tradeoffs, and communicate your design choices with confidence and clarity.
