Basic Game Development Patterns Questions

Understand and explain common game development patterns and when to use them. Core topics include object pooling for memory and allocation control, event systems such as publisher subscriber or observer patterns for decoupled communication, input handling strategies, game state management, coroutine and asynchronous patterns in modern engines, and spatial data structures such as quadtrees or spatial hashing for performance. Candidates should be able to implement, reason about complexity and memory trade offs, and describe optimizations or debugging approaches under time pressure.
