Topics follow a teaching order. Each answer ends with a clear Next question control so you can move forward without hunting the list.
Microservices interviews are the broadest backend topic — the module has the most topics because the surface is huge. This module is an elevation arc: it opens with fundamentals (what microservices are, why, the trade-offs), then service design (decomposition by business capability). The communication tier follows — API gateway, service discovery, load balancing, the patterns that make services find and talk to each other. Resilience (circuit breaker, saga) is the production tier, then observability (distributed tracing) and verification (contract testing). Feign, migration strategies, and service mesh close out the advanced tier. It closes with comparisons and scenario-based questions.

Interviewers rarely ask Microservices Architecture in isolation. These are the modules that most often come up in the same loop.
