Welcome to your interview.
The question is on your right: Design a Real-Time Prediction Platform. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
You are designing the prediction layer for a product that needs to score user or transaction events in real time. The system must serve predictions quickly, keep features fresh, and support model updates without disrupting traffic.
How would you design a scalable machine learning system for real-time predictions?
