Interview Questions to Ask Before You Hire .NET Engineers
Identify the right fit faster with these targeted technical and behavioral questions.
C# language & nullability
How do I enable nullable reference types and stop NREs in C#?
Add <Nullable>enable</Nullable> in the .csproj, use string?, safe calls ?., coalesce ??, and validate with ArgumentNullException.ThrowIfNull().
When should I use record vs class for DTOs?
record vs class for DTOs?Use record for value equality/withers and immutability; class when identity/mutation matter.
What’s the clean way to guard method inputs?
Use guard clauses and ThrowIfNull/OutOfRange; add [NotNull] and unit tests for contracts.
How do I avoid boxing/allocations in hot paths?
Prefer Span<T>, ReadOnlySpan<T>, pooled buffers, and string.Create; avoid LINQ in tight loops.
ASP.NET Core Web APIs
Minimal APIs vs Controllers, when should I pick each?
Minimal for small services/fast startup; Controllers for filters, conventions, versioning, and complex binding.
How do I return RFC7807 errors globally?
Configure UseExceptionHandler and map to ProblemDetails; enable [ApiController] for auto-400s.
How do I avoid socket exhaustion with HttpClient?
HttpClient?Use IHttpClientFactory typed clients, set handler lifetime, add Polly policies for retry/circuit-breaker.
What’s the right way to version APIs?
Add Microsoft.AspNetCore.Mvc.Versioning, version via header/path, and produce OpenAPI per version.
EF Core performance & data access
How do I kill N+1 queries in EF Core?
Project with Select to DTOs, use Include or AsSplitQuery(), and preload lookup sets.
Should I use AsNoTracking() by default?
AsNoTracking() by default?Yes for reads; use AsNoTrackingWithIdentityResolution() when joining graphs you still need de-duped.
What’s the fastest way to bulk insert?
Batch with EFCore.BulkExtensions or SqlBulkCopy; disable change tracking during bulk ops.
How do I handle concurrency correctly?
Add RowVersion (timestamp) columns and catch DbUpdateConcurrencyException with a merge prompt.
Async, concurrency & threading
How do I safely run I/O in parallel?
Compose tasks with Task.WhenAll, bound concurrency via SemaphoreSlim or Channels; avoid .Result/.Wait().
When is ValueTask worth it?
ValueTask worth it?When calls often complete synchronously and you control both sides; otherwise prefer Task.
How do I cancel work reliably?
Thread a CancellationToken from request to DAL/external calls; honor it in all awaits.
What causes deadlocks in ASP.NET Core?
Blocking async (.Result/.Wait()), sync over async in EF/HTTP, and thread-pool starvation.
Caching & speed
How do I add Redis cache without stampedes?
Use cache-aside with jittered TTL; lock around misses (e.g., DistributedLock), and short stale-while-revalidate.
What should I cache at API layer?
Stable DTOs, lookup tables, and user prefs; don’t cache secrets or per-request state.
How do I cut cold-start time?
Publish with ReadyToRun, trim unused assemblies, pre-warm, and enable Tiered PGO in modern .NET.
Where do I put response compression?
Enable UseResponseCompression for JSON; set correct MIME types and minimum body size.
Red Flags to Watch For
⭕ Blocks threads; no async I/O.
⭕ Leaky DbContexts, N+1 queries.
⭕ No logging, tracing, metrics.
⭕ Weak auth, secrets in code.
Additional Interview Questions
Microservices & resiliency
How do I implement idempotent handlers with outbox pattern?
Write domain + outbox in one transaction; a background publisher emits events; consumers dedup via inbox table keyed by message id.
What’s a sane retry policy?
Exponential backoff + jitter; only retry idempotent operations; cap attempts and add circuit-breakers.
How do I do canary releases with ASP.NET Core?
Route by header/cookie/percentage at the gateway/ingress; monitor p95/error budgets before full rollout.
How do I prevent cascading failures?
Time-outs everywhere, bulkheads (separate pools), and degrade to cached/placeholder responses.
Identity & security
How do I set up JWT auth quickly and safely?
AddAuthentication().AddJwtBearer(...) with short TTL access tokens, rotating keys, clock skew, and audience checks.
What’s the right approach to refresh tokens?
HttpOnly, Secure cookies, rotation per use, and server-side revoke list; strictly bind to client + IP if needed.
Where should I keep secrets?
Local: User-Secrets; cloud: Azure Key Vault/Parameter Store; never in code or build logs.
How do I protect against over-posting?
Use input DTOs, [BindNever], and model validation; never bind entities directly from the request.
Testing & CI/CD
How do I write real integration tests for minimal APIs?
Use WebApplicationFactory, seed a test DB (Sqlite/Testcontainers), call endpoints with HttpClient, assert payloads.
What should my test pyramid look like?
Heavy unit tests, focused integration, a few Playwright E2E; keep UI tests stable and parallel.
How do I test authenticated flows?
Stub identity handlers or mint test JWTs; for UI, preload Playwright storageState.
What CI gates actually catch regressions?
Static analysis, unit/contract tests, integration suite, then E2E on a prod-like env with artifacts retained.
Diagnostics & observability
How do I add OpenTelemetry to ASP.NET Core?
AddOpenTelemetry() with WithTracing/WithMetrics, auto-instrument HTTP/EF, export to OTLP (Grafana/Jaeger).
Which counters matter under load?
GC (% time/heap), thread-pool queue, Kestrel connections, exceptions/s; monitor with dotnet-counters.
How do I trace a single request across services?
Propagate traceparent/baggage; log correlation IDs in structured logs.
What’s a good logging baseline?
Structured logs (JSON), Warning+ in prod, PII scrubbers, and scoped ILogger per request.
