Mock Interview Scenario — “Design a Scalable Order System” Interviewer: “Design an order processing system using Azure for high traffic.” Weak Answer (Most candidates give): “I will use App Service, SQL Database, and Service Bus.” 👉 Rejected immediately (too generic) Strong Answer (What gets selected): I would design the system using event-driven microservices architecture to ensure scalability

Short answer: And fault tolerance. rchitecture: API Layer → Azure App Service Order DB → Azure SQL Messaging → Azure Service Bus Background processing → Azure Functions Cache → Redis Monitoring → Application Insights Flow:

Real-world example (ShopNest)

ShopNest’s API runs on Azure App Service with staging slots—swap staging to production after smoke tests.
