💬 Potential Interview Questions

What is the difference between .NET Core and .NET Framework, and why would you choose one over the other?
.NET Core is cross-platform and open-source, ideal for microservices and modern cloud applications, while .NET Framework is Windows-only and used for legacy systems.
How do you manage state in a React application?
State can be managed using React’s built-in useState and useReducer hooks, or external libraries like Redux or Zustand for more complex state management.
Explain the role of dependency injection in .NET applications.
Dependency injection promotes loose coupling and better testability by injecting required services into classes rather than hard-coding dependencies.
How would you structure a full stack application using .NET and React?
The backend would be an ASP.NET Core Web API serving data via REST or GraphQL, while the frontend React app consumes the API and handles UI and client-side logic.
What are some best practices for securing a .NET API?
Use HTTPS, validate input, implement authentication and authorization (e.g., JWT), and use IdentityServer or similar IAM tools for managing user access.
How do you handle errors in React and .NET?
In React, use Error Boundaries and try-catch in async code. In .NET, use global exception handling middleware and structured logging (e.g., Serilog).
What is your approach to continuous integration and deployment in a microservices environment?
Set up CI/CD pipelines using tools like Jenkins or GitHub Actions, integrate automated tests, and deploy to Kubernetes clusters with Docker containers.
What’s the role of IAM in modern software systems, and how have you implemented it?
IAM ensures only authorized users can access specific resources. Implementation may include OAuth2, OpenID Connect, and tools like Okta or Azure AD.
How do you optimize SQL Server queries for performance?
Use indexes, avoid unnecessary joins, review execution plans, and use stored procedures or parameterized queries to minimize query parsing and improve performance.
Can you describe a time you used test-driven development (TDD) in your work?
In TDD, I wrote unit tests before the code, focusing on small, testable components, which improved reliability and reduced bugs during development.
