• Use the STAR method: Situation, Task, Action, Result. Start by describing the context, then your specific actions (e.g., profiling, algorithm changes), and the measurable outcome.
• For technical questions, walk through your thinking process: identify the problem, analyze potential causes (e.g., memory bandwidth, compute units), propose solutions (e.g., tiling, data layout), and validate with benchmarks.
• Explain how you would optimize a neural network layer for execution on an NPU.
• Describe a time you profiled and improved performance of a parallel computing application.
• How do you approach debugging a low-level memory issue in C++ on an embedded system?
• What experience do you have with TensorFlow or PyTorch integration with custom hardware backends?
• How would you collaborate with hardware engineers to resolve a performance bottleneck?
• Review fundamentals of computer architecture, parallel computing, and ML building blocks (CNN, RNN, transformers).
