The C# online test assesses candidates' knowledge of programming in the C# 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 C# developer needs to be able not only to solve problems using C# 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 C# and find and fix bugs in a C# program.

Alert Service

10min

Easy

CODE

C# Refactoring Public

Refactor the AlertService and AlertDAO classes:

Create a new interface, named IAlertDAO, that contains the same methods as AlertDAO.
AlertDAO should implement the IAlertDAO interface.
AlertService should have a constructor that accepts IAlertDAO.
The RaiseAlert and GetAlertTime methods should use the object passed through the constructor.

Merge Names

10min

Easy

CODE

C# 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(new string[]{'Ava', 'Emma', 'Olivia'}, new string[]{'Olivia', 'Sophia', 'Emma'}) should return an array containing Ava, Emma, Olivia, and Sophia in any order.

Palindrome

10min

Easy

CODE

C# Strings Public

A palindrome is a word that reads the same backward or forward.

Write a function that checks if a given word is a palindrome. Character case should be ignored.

For example, IsPalindrome("Deleveled") should return true as character case should be ignored, resulting in "deleveled", which is a palindrome since it reads the same backward and forward.

What Others Say

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.

Jan Opperman, Grindrod Bank

Very smooth, well supported, great for assessing candidates

Very Prompt and helpful support when needed, we were looking to work with a third party to write and set up new tests, TestDome was able to quickly set up and support a method to do this, allowing us to start testing candidates straight away.

George Offer, Guided Solutions

Easy to use and efficient for testing developers of different levels

It provides us an opportunity to set our own timing policy, to choose from variety of questions from different areas and with difficulty gradation. Also it is great that TestDome provides free of charge tests for candidates to prepare and check how online IDE works. And support is always ready to help:)

Screening Applicants: The Good, the Bad and the Ugly

Since we’re all biased and we use incorrect proxies, why not just outsource hiring to experts or recruitment agencies? After all, they’ve been screening people for many years, so they must know how to do it right?

Not really. I was surprised to discover that many experts disagree with each other. Everybody praises their pet method and criticizes the others. Many of these methods look legitimate, but are based on...
