How our .Net framework tests work

DevSkiller .Net framework interview questions and tests are unlike other coding tests. We implement the RealLifeTesting™ methodology into our .Net framework online tests and ask candidates to solve problems that mirror the work they do in the real world. Our .Net framework tests provide recruiters with detailed insight into your candidates’ coding skills, problem-solving ability, and time-management skills.

Key features of our .Net framework coding tests

  • Testen Sie die Programmierfähigkeiten der Kandidaten und nicht nur ihre akademischen Kenntnisse
  • Verfolgen Sie in Echtzeit, wie der Kandidat die Tests absolviert, überall auf der Welt
  • Die RealLifeTesting™-Methodik bietet eine bessere Benutzererfahrung, bei der die Kandidaten ihre eigene IDE verwenden, zu Git klonen, Unit-Tests ausführen und für Recherchen auf Stack Overflow/GitHub/Google zugreifen können.
  • Mehrere Anti-Plagiatstools zur Sicherstellung der Prüfungsgenauigkeit
  • Automatisierte Ergebnisse, die auch von Nichttechnikern verstanden werden können

What to look for in .Net framework developers

.NET is a software development framework created by Microsoft. It was produced as Microsoft’s response to the popularity of the Java platform. .NET allows software to be easily developed, installed, and executed on Windows-based operating systems.

Your .NET framework developer should know of the varying .NET versions and the differences between them. They should also have demonstrable knowledge of the languages the .NET framework supports including C#, Visual Basic .NET, F#, and C++ .NET. There are a large amount of libraries and frameworks available to .NET developers and it is helpful to have a good knowledge of at least some of them, including .ASP.NET, MVC, or Entity Framework. They should also know about the various types of frameworks associated with .NET; Web frameworks, Desktop frameworks and Communication frameworks.

Commercial experience is important in a .NET framework developer.  You will want your candidate to have hands-on experience with a project that used .NET technology, even if that is not in a commercial sense.

.NET evolves quickly. The.NET Core framework, that supports  Windows, Mac, and Linux is similar to the .NET framework, but has its own nuances. One shouldn’t be seen as a replacement for the other. A .NET developer should be able to get to grips with using .NET Core easily enough.

Our .Net framework interview questions and tests will be able to assist you in narrowing down which candidates really have the knowledge needed to be your next .NET developer.

Build your own custom .Net framework interview questions and tests

Interested in trying .Net framework online tests but need a little more? Well did you know that with our online task wizard, you can build your very own custom tests? Customized tests allow you to change the languages/technologies and types of questions. You can also adjust the difficulty, and test-duration of your .Net framework tests.

Remote testing allows you to send test invitations to candidates all over the world. Finding your next .Net framework developer is easy with DevSkiller .Net framework interview questions and tests.

Want proof that our .Net framework interview questions and tests work?

It is understandable to want to seek assurances that our screening tool works before committing your company’s money. Check out this case study of one of our past clients for a little extra motivation:

DB1

DB1 develops robust and reliable software solutions for medium and large companies.

For their recruitment, the company had a 5 stage process, one of which was a technical challenge.

Candidates had 5 days to complete the challenge and some never got completed. Also assessment of the technical challenge required DB1 to have a developer present who could verify the answers. The process was slow and inefficient.

DevSkiller automated the technical screening stage of DB1’s recruitment and cut the entire technical test stage from around 5-10 days originally, down to 3-7 days with DevSkiller.

DevSkiller tests are assessed automatically which got rid of the need for DB1 to have a developer present. The experience also improved for the candidates and was much quicker.

Not only did DB1 quicken up their whole technical screening process, they are now more confident that the candidates they do select are the right ones for the job.

 “DevSkiller reduced the time on the technical test stage and reduced our dependence on other areas. It was faster to approve candidates for the next stage since we had an automatic score. Now the revision process is faster, most of the time we have instant results and scores that help us decide which candidate is approved to the next stage of the selection process. Our candidates say it’s a great platform and it really tests their knowledge.”

Nathalia G.R. Da Silva- Employer Branding & Tech Recruiter at DB1 Group

Häufig gestellte Fragen

Wie legen die Bewerber einen Test ab?

Devskiller .Net framework interview questions and tests are accessed remotely. Candidates can be tested from wherever they are, at any time they choose. Recruiters simply send the candidate a test invite. To make sure there is no waiting around, test invites can be set to be available only for a specific amount of time.

When taking their tests, candidates can use Devskiller’s state of the art in-browser IDE, they have the choice to complete the project on their favorite IDE and then clone the project to GIT.

Candidates can use normal procedures like running unit tests to make sure their solutions work the way they are supposed to.

Once the tests are completed or the time has elapsed, the test is automatically evaluated and the report is sent to the recruiter.

Wie lange dauert es, DevSkiller einzurichten?

DevSkiller is designed to be quick and simple to set-up. All you have to do is register your account and you can start sending out .NET framework tests.

There are hundreds of predefined coding tests at your disposal, for junior, middle, and senior-level. Assessment takes place automatically, so once the test invites are sent, you can sit back and wait for the report on how each candidate performed.

Was halten die Bewerber von den DevSkiller-Tests?

Candidates love the structure of Devskiller .Net framework interview questions and tests, because they are refreshingly different to the usual algorithm tests they get presented with. These tests don’t accurately reflect the actual skills of a .NET developer.

They also like the fact that DevSkiller tests use normal coding tools and conventions like unit testing. With DevSkiller testing, candidates appreciate the fact that they are being given a chance to prove their development skills in a fair setting
