Technical Skills & Experience

• 6. What are the key components of the .NET framework?
  Answer: The key components of the .NET framework include the Common Language Runtime (CLR), .NET Framework Class Library, and ASP.NET for web development.
• 7. Can you explain the difference between managed and unmanaged code?
  Answer: Managed code is code written in a language supported by the CLR and is executed by the CLR. It provides automatic memory management and error handling, ensuring better security and performance. Unmanaged code, on the other hand, is written in a language that is not supported by CLR and has to be executed directly by the operating system. It requires manual memory management and error handling.
• 8. How do you handle security vulnerabilities in a dot net application?
  Answer: I follow industry best practices and guidelines, such as regularly updating the application and libraries, implementing secure coding practices, and performing thorough security testing. I also stay updated with the latest security threats and take necessary measures to mitigate risks.
• 9. Can you explain the difference between ASP.NET Web Forms and ASP.NET MVC?
  Answer: ASP.NET Web Forms follow a stateful programming model, where the state of each control is maintained automatically by the framework. It provides an easy and quick way to develop websites, but it can lead to performance issues when handling large amounts of data. ASP.NET MVC follows a stateless programming model, where the state of each control is not maintained automatically. It allows for better control and flexibility over the application's performance and is more suitable for developing large and complex applications.
• 10. How do you ensure the scalability and performance of a dot net application?
  Answer: To ensure scalability and performance, I follow design patterns and principles, such as separation of concerns and dependency injection, implement caching, optimize database queries, and conduct load and stress testing to identify and address bottlenecks in the application. I also regularly monitor and analyze the application's performance to make necessary improvements.

Situational & Behavioral Questions

• 11. How do you handle a situation where there is a sudden change in project requirements?
  Answer: I communicate with stakeholders to understand their reasons for the change and the expected impact on the project. I then reevaluate the project plan and work with my team to adjust our approach and timeline to accommodate the change without compromising on quality.
• 12. Can you give an example of a time when you identified and addressed a critical technical issue in a project?
  Answer: In a previous project, I noticed a significant decrease in the application's performance after implementing a new feature. After thorough analysis, I identified a faulty database query and optimized it, resulting in a noticeable improvement in performance. I also reviewed and improved other queries to prevent similar issues in the future.
• 13. How do you handle conflicting priorities and tight deadlines in a project?
  Answer: I prioritize tasks based on their importance and urgency and communicate with stakeholders to align expectations. I also delegate tasks to my team members and assist them in completing their work on time. If necessary, I also negotiate with stakeholders to adjust deadlines and ensure the project's success.
• 14. Can you share a time when you had to lead a team through a complex project?
