Rendering and GPU Programming Questions

Authoring and optimizing rendering code and shaders and understanding graphics processing unit constraints and trade offs. Candidates should be able to write and reason about vertex fragment and compute shaders in languages such as High Level Shading Language OpenGL Shading Language or platform specific shading languages discuss shader instruction costs texture lookups branching overhead memory bandwidth and texture compression strategies reduce draw calls through batching and texture atlasing implement level of detail systems and streaming and profile rendering workloads across platforms including tile based renderers on mobile.
