Explain the principles of Clean Architecture (or Onion Architecture). Discuss the dependency rule and how it promotes separation of concerns.

Discuss patterns like Publish-Subscribe, Competing Consumers, and Sagas. Explain the role of a message broker (e.g., RabbitMQ, Azure Service Bus).

Discuss horizontal vs. vertical scaling. Explain patterns like load balancing, database read replicas, and database sharding.

Practice designing systems (e.g., URL shortener, Twitter feed). For each, start by defining key non-functional requirements like scalability, availability, latency, consistency, and cost, then discuss the trade-offs of your design choices.
