T4 Automotive and self-driving Zhuoyu New grad Round 1
Zhuoyu AI Infra campus hire first round
Zhuoyu AI Infra campus hire first-round interview questions covering inference optimization, operator optimization, and high-performance computing
Inference optimization Operator optimization High-performance computing
Operator optimization
- From profiling to production, what is the full operator optimization workflow? How do you tell whether an operator is memory-bound or compute-bound?
- Which profiling tools do people commonly use? Does Nsight Systems support instruction-level pipeline analysis?
- When warp utilization is low, how do you attribute the cause? How do you fix load imbalance?
- How do Ascend NPU and NVIDIA GPU differ in architecture? How is the memory hierarchy designed?
Fundamentals
- How do multi-process and multi-thread differ in performance?
- When model outputs do not match expectations, how do you debug? How do you handle error accumulation?
Inference optimization
- What are the principles behind model-level optimizations such as KV Cache, operator fusion, and quantization?
Project experience
- Walk through your project experience in depth.
