Entity Component System Design Questions

Focused on the entity component system architectural pattern used primarily in game engines and simulations. Key concepts include the separation of entities, components, and systems; component composition versus inheritance; data oriented design principles; memory layout and cache friendliness; vectorization and single instruction multiple data considerations; serialization and networking of components; lifecycle and dependency management for systems; and trade offs when adopting ECS versus traditional object oriented hierarchies. Candidates should demonstrate understanding of performance implications, concurrency models, and typical use cases for ECS.
