Weapons system

Identifying design patterns in a C++ weapons hierarchy

This easy question asks you to recognize a structural design pattern in an existing codebase. It tests whether you can read object-oriented code and map its structure to one of the classic Gang of Four patterns—a skill that matters when code review, refactoring, and architectural communication are part of the job.

The scenario involves a weapons system where base weapons can exist in multiple rarity forms. Rather than asking you to implement from scratch, the question gives you working code and asks you to name the pattern. This approach is common in interviews at firms like Microsoft, where engineers often inherit and maintain complex systems and need to recognize design patterns quickly to reason about extensibility, coupling, and where to add new features.

• Structural vs. creational vs. behavioral patterns
• Inheritance and composition tradeoffs
• How patterns reduce code duplication and improve maintainability
• Recognizing patterns from code structure rather than intent alone
