Sr. Data Engineer Top Tech Architecture
The Signals That Power Recommendations
Our personalization platform powers product recommendations for millions of users. It needs a continuous feed of user interaction signals - clicks, purchases, saves, and ratings - from multiple product surfaces and a feature computation layer that keeps user profiles current. Different teams own different signal sources and have different latency requirements. Design the ingestion and feature pipeline.
Ask the interviewer clarifying questions to understand the requirements and constraints before designing.
