Premium questions with real-world problems

The VB.NET online test assesses candidates' knowledge of programming in the VB.NET language and their ability to leverage commonly used parts of the .NET framework's class library.

It's an ideal test for pre-employment screening. A good VB.NET developer needs to be able not only to solve problems using VB.NET but also recognize when to leverage the functionality provided by the .NET framework's class library to write robust and maintainable code.

This online test requires candidates to solve coding problems in VB.NET and find and fix bugs in a VB.NET program.

Our sample questions are free for companies to use on a trial plan. See more about our premium questions for paid plans below.

Merge Names

CODE

VB.NET Arrays Public

Implement the UniqueNames method. When passed two arrays of names, it will return an array containing the names that appear in either or both arrays. The returned array should have no duplicates.

For example, calling MergeNames.UniqueNames({'Ava', 'Emma', 'Olivia'}, {'Olivia', 'Sophia', 'Emma'}) should return an array containing Ava, Emma, Olivia, and Sophia in any order.

User Input

CODE

VB.NET Inheritance OOP Public

User interface contains two types of user input controls: TextInput, which accepts all characters and NumericInput, which accepts only digits.

Implement the class TextInput that contains:

  • Public sub Add(c As Char) - adds the given character to the current value
  • Public function GetValue() As String - returns the current value

Implement the class NumericInput that:

  • Inherits TextInput
  • Overrides the Add method so that each non-numeric character is ignored

For example, the following code should output "10":

Dim input As TextInput = New NumericInput()
input.Add(CChar("1"))
input.Add(CChar("a"))
input.Add(CChar("0"))
Console.WriteLine(input.GetValue())

Folders

CODE

VB.NET Serialization XML Public

Implement a function FolderNames, which accepts a string containing an XML file that specifies folder structure and returns all folder names that start with startingLetter. The XML format is given in the example below.

For example, for the letter "u" and XML file:

<?xml version="1.0" encoding="UTF-8"?>
<folder name="c">
    <folder name="program files">
        <folder name="uninstall information" />
    </folder>
    <folder name="users" />
</folder>

the function should return "uninstall information" and "users" (in any order).

Pass/fail grouping

Our tests are designed to put candidates into either the pass group or the fail group so you can find the best candidates faster.

Full customization

We have pre-built tests and questions, but you can customize them however you like. Change the pass/fail scores, time requirements, and more.

Cheating protection

Use tests that solve real-world problems, with no answers that can be easily found online. Because we test performance and skills (not information), we allow the use of online resources, just like in real life. Copy/paste prevention and online proctoring via webcam prevent cheating.

Candidate reporting

Get an overview into the percentage of passes and fails. Then dive deeper into the results of your top candidates to select who goes onto the next phase of hiring.
