FAANG Specific Technology and Culture Questions
Understanding of what makes each FAANG company's technical challenges and culture unique. Google focuses on scale and distributed systems. Amazon emphasizes customer obsession and operational excellence. Meta focuses on mobile and infrastructure. Apple emphasizes hardware-software integration and user experience. Netflix is known for microservices and freedom and responsibility culture. Microsoft has become increasingly cloud-focused with Azure. Understanding each company's technical philosophy helps you source engineers who align with that culture.

You are asked to hire an AI research team that must deliver both publishable research and production-grade systems (a common tension at Google and Meta). Design role definitions, performance evaluation criteria, incentives, and career progression paths that balance open research with production delivery while avoiding perverse incentives (e.g., publishing at the expense of product quality).

In Python, implement a utility that quantizes a PyTorch nn.Linear layer's weights to 8-bit integers and provides a dequantize method for inference. Support both per-tensor and per-channel quantization options, and provide a brief explanation of the accuracy vs compression tradeoffs. Keep the API simple and testable (no need for GPU acceleration).

Explain key differences between how Google, Amazon, Meta, Apple, Netflix, and Microsoft approach AI infrastructure and product priorities. For each company, name one technical challenge an AI engineer is likely to face and one cultural/value-driven decision that would shape how you solve that challenge (e.g., scale-first, customer-obsession, mobile-first, hardware integration, freedom-and-responsibility, cloud-first).

Implement an offline log-analysis tool in Python that helps detect microservice regressions caused by a new ML model version (Netflix-style). Input: JSON lines logs with fields {request_id, timestamp, model_version, latency_ms, error_flag, user_cohort}. The tool should aggregate by model_version and user_cohort, detect statistically significant regressions in latency or error rate (choose an appropriate test), and emit a short actionable alert summary per regression. Focus on correctness and explainability, not performance.

Case: Amazon must deploy a real-time fraud detection model into their payments pipeline that has sub-100ms latency and five-nines availability. Describe an organizational change-management plan for this rollout: stakeholders to involve, phased rollout (canary, shadow), instrumentation to measure customer impact, governance/approval steps, and how to embed 'customer obsession' into KPIs.
