Your question is REST vs gRPC. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain the differences between REST and gRPC and their typical use cases.
Asked in the Advanced DSA + system discussion stage. Compare the protocols practically, including communication style, serialization, contracts, streaming, performance, observability, compatibility, and deployment considerations. Explain when you would choose each for service-to-service communication, public APIs, browser clients, and latency-sensitive systems. Mention relevant failure modes and migration considerations.
