What to ask ASP .Net Developers when hiring for your IT project?

Warm-up with the general requirements, which should be quite simple for anyone who has knowledge of ASP.NET Development. 

Listen carefully to how candidates respond and how they communicate to solve problems...

1. What is ASP.NET and why do we use it?

Here, some candidates will focus on development and consider ease of deployment, multilingual help, or compatibility with popular databases. Other respondents may be more impressed with the results, such as how ASP.NET can be used to create dynamic websites and applications, how it can easily grow in scale, and support the global development community.

Either way, this question will tell you a lot about how candidates view the role of ASP.NET Developers. This will also help you assess their ability to explain complex technical concepts to non-specialists, this is an important soft skill.

2. What is ASP.NET Core?

ASP.NET Core is an open-source version of Microsoft ASP.NET. First released in 2016, ASP.NET Core runs on macOS and Linux, as well as Windows. The framework has been extensively rewritten, with changes such as MVC and Web API in one model.

3. How does .NET support multiple languages?

The answer to this question in ASP.NET interviews can be deceptively difficult, but it helps candidates who only know the fact that.

The strong answer to this question may sound as follows: 

“To be classified as. NET language, it must meet the general standard for language duration. In .NET, the code is embedded in the Microsoft intermediate language. Once as the intermediate language, the language is not a barrier. The code can use or call functions written in other languages. ”

4. What is Postback?

Feedback occurs when clients request a response from the server on the page they are viewing. A simple example of this is a user who fills out a form and clicks on the "Submit" button. In this case, the IsPostBack function is valid, so the server processes the request and sends a response to the client.

The return mail will refresh the whole page and without simply restoring the data, the request will be refreshed without a full refresh.

Once you know the basics, you can further assess the ASP .NET Developers candidates' knowledge with these more in-depth questions:

5. If the try-catch block fails to find an exception, what will happen to the block in the end?

Try-catch is a method for handling exceptions in C # and other languages. This is actually Plan B - the way to say "try

and if it doesn't work, do it". After all, the block happens then and always executes if there was an exception.

Try to catch up and finally become more familiar with more experienced developers who have worked in a production environment.

6. What are the advantages and disadvantages of consumer control and personal control?

There are two main areas of this question: Knowledge of interviews and their approach to ASP.NET application design. It is important not to focus on factual questions, the answers to which you can easily find on the Internet.

Measuring candidates' ability to apply what they have learned is much more useful. Some important differences between client and custom controls:

Creating custom controls is easier, but there is limited support for users using visual design tools. They are best suited for static layout.

7. What are some of the page events in the ASP.NET page lifecycle?

The ASP.NET page life cycle goes through several different events during page startup. This question is of a technical nature for ASP .NET developers, as it requires familiarization with the entire life cycle, as well as the process of implementing and maintaining the correct code and controls for each stage.
