Our .NET and C# test online use coding tests powered by the RealLifeTesting™ methodology. In these tests, the candidate is asked to build or add new features to an application using the languages and components of the .NET framework. Instead of having a separate C# online test and ASP.NET online test, our test lets developers use frameworks and libraries to show off their coding skills, business logic, problem-solving skills, and ability to meet deadlines.
.NET is an extensive software development framework developed by Microsoft. It provides a controlled environment where software can be developed installed and executed across the web, desktop, and mobile. Originally developed just for the windows environment, .NET Core now allows .NET application do be developed across platforms. C# is an
C# is one of the primary languages used by .NET but it is not enough to only be able to use the language. An effective .NET developer needs to be familiar with and be able to use key features of the framework like ASP.NET, MVC, Entity Framework, WCF, LINQ, and other resources. They should also be familiar with .NET build tools like MSBuild.
Do you want to give a .NET and C# online test using your own codebase? No problem. Our task wizard allows you to build your own coding test using your own resources. You can send your test to candidates anywhere in the world and see how they perform doing the task of your choosing. Finding your next .NET and C# developer is easy with a .NET and C# test online.
It can sometimes be difficult to know how effective something can be if you’ve never tried it. After all, our DevSkiller C# online tests are different from traditional algorithmic tests. Instead of taking our word for it, have a look at what some of our past customers have to say:
“The duration of the recruitment process has not changed, but we spend less time and effort per candidate. We also don’t waste time on the wrong candidates.”
“We’ve replaced a high-maintenance in-house solution with DevSkiller. Our process looks the same, however, the product gives us better performance. The results are also way easier to assess.”
“DevSkiller helped us to save precious on-site time for applicants that are already likely to be a fit. We’re saving 3 hours per candidate – that was the time we spent with applicants on a technical task before.”
One of the main advantages of DevSkiller testing is that our .NET/C# online tests are evaluated automatically, as soon as the candidate is finished, or their time has run out.
Candidates are assessed on several contributing factors. Whether or not the solution they came up with would run (an essential factor in all software development). How their solution would perform in edge cases and the content and quality of their code. Successful candidates are those who can demonstrate their critical thinking skills and manage their time effectively, to be able to progress.
The result for our .NET/C# online tests are compiled into clear, easy to follow reports, that non-technical professionals can understand.
To avoid hours of in-house testing, Devskiller’s .NET/C# online tests are accessed remotely and can be taken from anywhere in the world. All the recruiter has to do is send the candidate a test invite. If you prefer, recruiters can even monitor test progress in real-time so it is just like being in the same room.
The test invites can be made available for a specified amount of time so the recruiter is not kept waiting. The candidates can then start the test whenever is convenient for them within that time.
When it comes to the test itself, candidates have the option of using DevSkiller’s state of the art in-browser IDE or they can complete the project on their favorite IDE and then clone the project to GIT. During the C# online tests, if they desire to test their work as they go along, then candidates can run unit tests to make sure their solutions work the way they are supposed to.
The duration of our C# online tests is flexible and is really the decision of the recruiter. Each C# test comes loaded with default settings, including a default duration, but these can be easily adjusted. It is even possible to set time limits for individual questions within a test if required.
Developers’ reactions to our .NET/C# online tests are by and large, very positive. The vast majority of candidates seem to relish having the chance to prove their software development skills. On the odd occasion, a developer’s reaction is not as we would expect, we find this is usually just an initial reaction to having to take the tests. Many developers have grown wary of developer testing because in the past they have been subjected to boring algorithm tests that don’t reflect the actual development work they do. Once they see our C# online tests and that our approach to developer testing is different, then they are usually very keen to show what they can do.
Developers appreciate the fact that our C# online tests allow them to use normal coding tools and conventions like unit testing, and cloning to GIT from a personal IDE. DevSkiller testing is more accurate to the work developers are used to performing, and they appreciate the chance to prove their skills.
