C Test

C is one of the oldest programming languages still in use, and it forms the basis of many other coding scripts. The C Test evaluates the candidates’ proficiency in using the language, and their ability to apply their understanding to work-related situations.


What is a C test?

The C Test is a pre-employment assessment that has been created to evaluate applicants based on their ability to use the C language in different situations. The test is multiple-choice and is completed remotely via an email link. The results can be used by the recruitment team to select the most competent candidates to take further in the recruitment process.

Screening tests like the C test are becoming more popular in recruitment funnels because they are straightforward for the candidate to complete, and they give the recruitment team all the unbiased data that they need to make a rational decision about which candidates have what it takes to be successful in the role that has been advertised.

About the C Test

The C Test evaluates candidates on their ability to use this general-purpose programming language. As the C language is the basis of many more comprehensive programming languages used both in backend and frontend development, strong knowledge of the different applications of this structured and machine-independent language usually means that a candidate will find it easier to learn and use other languages too - so testing for C proficiency is useful in a number of developer-related roles.

Why should you use a C test?

As a base programming language that is used widely in embedded systems, C is related to many other scripting tools, which means that a candidate who can demonstrate proficiency in this language will be more likely to be able to use complementing software and programming systems.

It is difficult to evaluate the candidates’ knowledge of the C language by solely relying on the process of screening resumes or conducting interviews - but the C test is a great screening tool to see just how competent each candidate is.

The test poses questions that allow every candidate to show that not only do they know and understand the language, they are also able to apply it to different situations, from developing systems and desktop apps to creating browsers and extensions. C programmers can use the scripts to create databases like MySQL, for example, and also Internet of Things (IoT) applications.

The C Test would be useful in the early recruitment process for a number of different roles, including:

The test is simple for the candidate to complete, and for the recruitment team it provides unbiased, quantifiable data about the proficiency of each candidate, so the top performers can be selected to move further into the hiring process.

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.

Neuroworx Sample Report

How our test assesses C skills

In Neuroworx’s C test, candidates will need to answer a range of questions targeting an intermediate level of proficiency, from demonstrating knowledge about the programming language to interpreting code to solve common issues.

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 analyzed to maximize reliability and validity in line with industry best practices. It was created and tested 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 optimized for performance.
