C# Test

C# tests are designed to assess a candidate's knowledge and understanding of the C# programming language.

  • What is a C# test?

    A C# test assesses someone’s knowledge of C# and ability to leverage the .NET framework’s class library to help write stable code. It is one of the biggest programming languages and is often used by full-stack developers (those who deal with both the front and back end of an application or website).

    The test includes practical problem solving that demonstrates basic knowledge and understanding of how to use C#, such as implementing user interface, alert service, and name merger.

    A high-performing candidate should be able to solve problems using C#, including bugs in the language, as well as know when to leverage the .NET framework’s functionality.

About the C# Test

C# is a general-purpose programming language developed by Microsoft in 2000. It is object-oriented programming that is widely used when developing enterprise software, desktop and mobile applications, and games.

As one of the most versatile software development tools, it is a top choice for almost all needs when it comes to web development and engineering. Using a C# test means that it is easier to find the candidate who has the skills to meet your needs, improving the process for all parties.

  • Why should you use a C# test for recruiting?

    When it comes to hiring someone for software development, it can be difficult for recruiters to make an informed decision if they do not have the knowledge and ability to reliably test the candidates. As the workforce becomes more highly educated, it is likely that you are faced with similarly qualified candidates on paper and no reliable way of differentiating skill levels.

    This makes a C# test an ideal way to find the best candidate for the position that you are recruiting for as it is an objective demonstration of key skills for jobs like:

    The test is developed by experts in the field who understand what a highly skilled C# developer should be able to do. Therefore, the test will help you make an informed decision even when the candidates seem similarly qualified.

    A full report on the results of each test will show you exactly how the candidates performed, making sure that you find the person who can fulfill the role.

    C# developers are in high demand across the board as interactive websites and applications are vital for businesses. Whether you hire an in-house developer or outsource, this test can ensure that you are hiring the right person the first time round.

Sample C# Test question

Which of the following is the correct way to overload +operator?

  • public static operator + (sample a, sample b)

  • public abstract operator + (sample a, sample b)

  • public sample operator + (sample a, sample b)

  • all of the above

Results for the C# Test along with other assessments the candidate takes will be compiled to produce a candidate report. The report is automatically generated and available both online and as a downloadable pdf so they can be shared with other team members and employees alike.

How our test assesses C# skills

In Picked’s C# test, candidates will need to answer a range of questions targeting an intermediate level of proficiency, from demonstrating their knowledge and understanding of core functions to solving bugs in the code. The test is designed to indicate how well a candidate understands C# based on a final test score, which can then be compared to the scores of other applicants.

The multiple-choice questions consist of one correct answer and two-to-four distractors. The distractors are mostly generic mistakes or misconceptions, which makes the test challenging and helps measure a candidate’s proficiency more accurately.

During the development process, the test was rigorously analysed to maximise reliability and validity in line with industry best practices. It was created and revised by programmers and psychometric experts, and field-tested with a representative sample of job applicants who have varying C# experience, just like you might find in a talent pool.

Each test is reviewed by a panel of individuals representing diverse backgrounds to check for any sensitivity, fairness, face validity and accessibility issues. This ensures each programmer has a fair chance of demonstrating their true level of C# proficiency and feels the test is of high quality.

Our programming tests are monitored to ensure they are up-to-date and optimised for performance.

C# Test FAQs

What is C# used for?

C# is a multi-paradigm programming language that has a syntax similar to Java and C++. It was developed by Microsoft software engineers to meet the demand for more complex web applications and is used for general website and application development.

The game engine Unity, which is used to develop 2D and 3D games, also uses C# as its scripting API, making it a growing choice in the gaming industry.

Where in the application process is it best to use a C# test?

While you can use the test at any point during the recruitment process, it is recommended to use it early on as a screening test. By doing this, you will be able to quickly and easily shortlist the candidates with the skill level you are looking for and, therefore, know who to progress to interviews or a job offer.
