How do you design the system for centralized application
Asked in the Technical stage. Architecture design question. Treat this as a practical ML system design exercise: clarify the application scope, define service boundaries, and explain how centralized data and model serving would operate reliably at scale. Discuss assumptions explicitly rather than relying on unstated product context.
Address the request path, offline data and training path, deployment model, observability, security, scaling, and failure recovery. Explain which parts are online versus batch, how models and features are served, and how you would evaluate changes.
