Your question is Design for High-Traffic Scenarios. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you design a system to handle a specific high-traffic scenario at Perk?
Clarify the product surface, users, traffic patterns, business objective, and ML decision being made before proposing an architecture. Explain how you would size the system, choose between batch and online inference, address latency and cost, evaluate quality, and monitor failure modes including feature drift and training-serving skew.
