What this interview tests
- Python web stack performance optimization (FastAPI, Flask)
- GPU-integrated Python workloads (CUDA-aware Python, TensorRT, torch.compile, ONNX)
- Internal developer platform / library design
- Low-latency, high-throughput distributed systems performance
- Judgment on risk-aware change management for foundational infra
Common question themes
Walk through a real Python performance optimization you did — how did you profile and what changed?
How would you decide what functionality belongs in a shared internal Python library vs. team-owned code?
Describe your hands-on experience integrating Python with GPU workloads (CUDA, TensorRT, or similar)
Tell me about a time you chose a conservative, lower-risk technical approach over a more modern one, and why
How do you gather requirements from internal 'customers' (other engineering teams) and prioritize platform work?
