About this page

gRPC is a single-topic module. This module covers gRPC fundamentals — protocol buffers, the four service types, streaming, deadlines, interceptors, error handling — organized as an elevation arc within the one topic from 'what is gRPC and why vs REST' through to production patterns.

REST API & Spring MVC Interview Questions

REST API interviews are the bread-and-butter backend surface. This module is an elevation arc: it opens with REST fundamentals (what REST is, the constraints, Richardson maturity), then request/response handling and Spring MVC controllers (the code tier). REST clients (RestClient, WebClient, Feign) follow, then the design tier — error handling, versioning, API design, HATEOAS, OpenAPI. HTTP caching closes the production tier, then comparisons and scenario-based questions.
