C# Developer Test

Use a C# test to hire developers by testing their knowledge and understanding of C#.

  • What is a C# test?

    If you are recruiting a developer who knows the .NET framework, then the C# test is a useful way to assess each candidate based on their level of proficiency and understanding of this programming language.

    Developed and launched by Microsoft, C# has a similar structure and syntax to JavaScript and C++. Using the language developers and programmers can create apps, databases, and even games.

    The test assesses each candidate on their knowledge of the C# architecture and structure, as well as their understanding of the syntax used in creating code. They will also need to confidently apply the .NET class library to create and develop programming code relevant to the needs of the business.

  • Why is a C# test so important when hiring?

    Developer roles, especially for a well-known programming language like C#, are popular in all sorts of industries, and this means that as a recruiter it can be difficult to sort the best applicants.

    Although there are qualifications in using C# available, it can be difficult to assess a candidate on their actual ability to use the language and understand the architecture using traditional methods like CV reading or even in an interview.

    The C# assessment takes the guesswork out of deciding on a candidate's skills by providing accurate, real-time, and quantifiable data about the skill, ability and proficiency of the applicant that can be used as part of the selection criteria.

    The questions asked in the assessment are relevant, and should be reasonably straightforward for a candidate who has the required knowledge - so the recruitment team can choose the candidates who perform the best in the test to take further in the application process.

    The C# test is simple to deliver at scale and can be used for a range of job application processes for several different roles, including:

    • App Developer
    • .NET Developer
    • Software Architect

    As a general-purpose coding language, C# is one of the most popular programming systems in the world, and because it can be used to create so many different applications and programs, it has uses outside of the IT department. C# developers can create video games and mobile apps, create entire Virtual Reality worlds and power extensive databases.

    Knowing that the candidates that are applying for your advertised role have enough skill and knowledge to use C# properly and confidently saves time and money in the recruitment process, and reduces the risk of poor hires or additional training needs.

Sample C# Developer Test question

Which of the following is true about the Hashtable class in C#?

  • It is not thread safe.

  • It does not return null if a key does not exist.

  • It is loosely typed.

  • It uses only unboxing to retrieve data.

How to assess C# coding skills using our test

Our C# test asks a variety of questions that vary in difficulty level. Candidates who are proficient in C# should be able to answer most of the questions correctly.

The C# test provides valuable data-driven insight into what a candidate knows and understands. The test is structured using multiple-choice questions: a familiar format for most test-takers, that allows for instant and objective scoring.

As well as the correct answer, there are typically 2–4 distractors, representing common misconceptions and mistakes. This helps make the test more challenging, so a candidate's ability can be measured more accurately.

Test scores are provided to the user and can be compared to other test-takers in your talent pool to see how they perform relative to each other.

Each test has been thoroughly reviewed to ensure accuracy and validity in line with industry standards. It has been written, examined and edited by C# experts and psychometric professionals. It has also been reviewed by a diverse sample of job seekers to check for any issues including sensitivity, face validity, fairness and accessibility.

This test is continually monitored so our team can optimize performance and regularly assess fairness issues.

What is C# used for?

C# is a programming language that has many uses. As a general-purpose language based on a similar structure and syntax to C++ and JavaScript, C# works on the Microsoft .NET framework and can be used to code games, apps for mobile, desktop and the web, and also create databases.

How popular is C#?

C# is the third most popular programming language behind Python and C++, which makes it a skill that is worth having if you are a front end, back end, or even a full-stack developer. The similarity of the language in C# to JavaScript and C++ makes the skills transferable between these three languages in particular.

What other skills are required for C#?

As with all coding and programming, understanding the structure and syntax of commands is necessary for agile use of C#. Users need to be able to think logically about a problem and have great critical thinking skills. The best C# developers are excellent team players who can communicate complicated code structures to non-users in a succinct and understandable way.

Why is knowledge of C# important?

C# is a well-known and well-used language, and as it is used in the .NET framework of Microsoft, its popularity is growing. C# knowledge can be applied in the back end and customer-facing design, as well as in developing apps that are easy to use for both customers and businesses.
