API request handling, routing, contracts, validation, error handling, and production behavior.
Practice items tagged with Backend APIs.
Compare controller ActionResult patterns with minimal API typed results and explicit HTTP outcomes.
Explain API behavior when data and operations cross services with separate data ownership.
Explains attribute routing, binding-source inference, automatic validation responses, and where explicit domain validation still belongs.
Partitions limits by authenticated user or trusted client address and returns useful 429 retry metadata.
Design and debug rate limiting while protecting the API without blocking legitimate users and integrations.
Explains how ASP.NET Core schemes select handlers and why authenticate, challenge, and forbid produce different security behavior.
Preparation paths where this taxonomy appears in the track scope.
Full-cycle .NET full-stack interview preparation.
A role-based preparation path covering C#, ASP.NET Core APIs, data access, frontend integration, testing, deployment, system design, real-life scenarios, and behavioral interview topics.
Backend-focused .NET interview preparation.
A backend-focused .NET preparation path covering C#, ASP.NET Core APIs, data access, reliability, testing, and practical coding.
Build the endpoint, protect its boundaries, and make failure behavior explicit.
A hands-on ASP.NET Core interview track covering typed contracts, validation, list queries, overposting, idempotency, concurrency, bulk writes, capability and resource authorization, secure files, downstream calls, durable jobs, webhooks, and rate limiting.
Prove API behavior, reproduce failures, and leave durable regression evidence.
A practical ASP.NET Core track covering authenticated integration tests, capability and ownership boundaries, ProblemDetails, idempotent retries, stable pagination, cancellation, concurrency, database command guards, correlated failures, distributed tracing, connection-pool pressure, health checks, incident regressions, and post-deploy smoke checks.
