VB.NET interview questions are what recruiters ask developers when they're assessing knowledge and skills associated with this computer programming language. VB.NET started as VB (Visual Basic) and later evolved into a Microsoft object-oriented programming language to facilitate easy web services and web development. Learning about VB net interview questions can help you prepare answers for technical queries about this programming language and your familiarity with it. In this article, we discuss various interview questions for VB.NET developers, provide example answers to help you make a favourable impression during your interview and give useful tips to help you during the process.

In-depth technical questions

Expect technical questions during a VB.NET interview, as this is how an interviewer can assess your knowledge of this programming language. Here are some examples:

  1. What's the primary point of distinction between VB and VB.NET?

  2. Describe the differences between C# and VB.NET.

  3. How do you use VB.NET coding to create namespaces?

  4. What's your approach to creating a function in VB.NET that can accept a varying range of functions and arguments?

  5. What is JIT and how do you apply it?

  6. Describe the relationship between assemblies and namespaces.

  7. What are dynamic arrays in VB.NET?

  8. Which class acts as a base class for all exceptions in VB.NET?

  9. Explain the terms variable and constant in a VB.NET context.

  10. What's the difference between authentication and authorisation?

Interview questions with sample answers

Here are some examples of specific questions interviewers can ask during an interview, along with sample answers:

1. What's the difference between shared variables and shared methods?

This is an example of a technical question an interviewer can ask you to evaluate your understanding of VB.NET coding. Go beyond the textbook definition of both concepts and provide an example from your experience.

Example: "I can execute a shared method without creating an object of a class, but a shared variable depends on the shared method I apply. It isn't associated with specific classes or structures. This makes it a function that I can apply to different shared methods."

2. How do you store and retrieve images within an SQL server database through VB.NET?

An interviewer may ask this question to assess how you organise the steps in a project and how you apply your technological skills. Describe the steps briefly and clearly, using an example from your prior experience, if possible.

Example: "I'd first convert the files to byte streams with the IO.MemoryStream because image files are stored on an SQL server in bytes. This way, I can save the stream of the bytes in a table with each image data type. I can then transfer the table to the web application or an internal communication application I'm working on."

3. Why do you use an assembly keyword?

When interviewers ask this technical question, it's to gauge a candidate's knowledge of the functions within a .NET application. In your response, mention instances when you used assembly keywords and why.

Example: "An assembly keyword specifies that attributes found at the beginning of a specific source file will apply to the whole assembly built in VB.NET. One way to use assembly keywords is to indicate the methods of expression modified within the code when using VB.NET in a web application."

4. Are you familiar with other coding languages supported by VB.NET?

This is a way for interviewers to see whether you can work on projects that require other coding languages that the VB.NET framework supports. Mention which VB.NET-supported coding languages you're familiar with and your experience in using them.

Example: "I'm proficient in COBOL and used it on several web development projects when I worked with a banking company. I'm also familiar with C# and use it on projects that require me to define classes and methods with generic placeholders. In addition, I'm learning about Perl and its applications.”

5. When do you execute early binding in a VB.NET framework?

Your answer to this question can give the interviewer an idea about whether you know when to execute different functions when running applications in a .NET framework. Use any experience you have in web development to demonstrate your skills in this capacity.

Example: "I'd execute early binding before completely opening and running an application. I'd use late binding while going through the quality assurance procedure as a runtime binding to evaluate the application for optimum functionality."

6. What are the differences between DataSet and DataTable?

An interviewer may ask this question to assess how effectively you can create ways to store and organise data. Give examples of how you can use both functions so you can demonstrate your attention to detail and analytical skills.

Example: "The fundamental difference is that DataSet can hold a large number of tables for various data, but DataTable can only store one table. They're different concepts but you can use both to streamline documentation and save time. For instance, I can use data tables for individual reporting tasks, such as queued projects and completed projects. After this, I can categorise and store these tables within their respective data sets.”

7. What's the difference between client-side and server-side in a VB.NET application? How do you use them?

Your response to this technical question helps an interviewer gauge your working knowledge of creating web applications using VB.NET as a framework. Mention any experience you have with this programming language to describe the differences between each function.

Example: "Within the VB.NET framework, a server-side code executes on the server when submitting a page through specified controls. These controls trigger an event that submits the web page on the server-side of the application. The client-side code only executes on the client's browser but doesn't submit the page. For example, if I create an application in ASP.NET with a web control that executes at the click of a button, it'll submit the page on the server-side while attaching events on the client's side."
