Here’s a comprehensive .NET interview preparation guide tailored for professionals with 8+ years of experience. This guide covers advanced C# concepts, architecture, system design, real-world scenarios, and soft skills expected at senior levels.

---

• OOP Principles (Inheritance, Polymorphism, Abstraction, Encapsulation)

• Abstract Classes vs Interfaces

• Delegates, Events, Func, Action, Predicate

• LINQ (projection, filtering, joins, grouping, aggregates)

• Exception Handling (best practices, custom exceptions, retry patterns)

• Async/Await, Tasks, Parallelism, CancellationTokens

• Generics (constraints, variance, use in collections and services)

• Memory Management & Garbage Collection

• Reflection & Dynamic Code

• Records, Tuples, Value Types (readonly struct, record struct)

• Nullable Reference Types

• Indexers, Iterators (yield return), Attributes

• .NET Core vs .NET Framework vs .NET 5/6/7

• GC internals, JIT, value vs reference types, boxing/unboxing

• Configuration & dependency injection

• Logging and diagnostics (ILogger, Serilog, etc.)

• Singleton, Factory, Strategy, Decorator, Adapter

• Repository, Unit of Work

• CQRS, Mediator (with MediatR)

• Dependency Injection patterns

• SOLID Principles, DRY, KISS, YAGNI

• ASP.NET Core middleware pipeline

• Filters (Action, Exception, Authorization)

• Authentication/Authorization (JWT, OAuth2, Identity)

• Rate limiting, caching (Memory, Distributed)

• API versioning, pagination, OpenAPI/Swagger

• Model validation, custom model binders

• Global error handling

• Code-first vs DB-first

• LINQ-to-Entities vs LINQ-to-Objects

• Change tracking, lazy loading, eager loading

• Transaction management, raw SQL

• Migrations and versioning

• Performance tuning (N+1, compiled queries)

• Layered, Onion, Clean Architecture

• Microservices vs Monoliths

• Domain-Driven Design (DDD) basics

• Communication patterns (REST, gRPC, message queues)

• Caching strategies (Redis, in-memory, cache invalidation)

• Security (XSS, CSRF, HTTPS, OWASP top 10)

• Logging (Serilog, ELK, Seq)

• Scaling, load balancing, fault tolerance

• xUnit/NUnit, Moq, FluentAssertions

• Test-driven development (TDD)

• Integration testing (WebApplicationFactory)

• Mocking frameworks

• Code coverage

• Azure DevOps / GitHub Actions / Jenkins pipelines

• Azure services (App Services, Key Vault, Storage, Service Bus)

• AWS equivalents (Lambda, S3, API Gateway)

• Docker (Dockerizing .NET apps)

• Kubernetes basics

• Terraform/Bicep for IaC
