About the test

The C# and .NET online test assesses candidates' knowledge of programming in the C# language and their knowledge of the .NET Framework.

It's an ideal test for pre-employment screening. A good C# developer, capable of working on the back-end or the full-stack of an application, needs to be able not only to solve problems using C# but also to leverage the utilities and classes provided by the .NET Framework.

This online test requires candidates to solve coding problems in C# and answer questions about the features of the .NET Framework.
