C (coding): entry-level algorithms

C programming test: Pre-employment screening assessment to evaluate candidates' algorithm skills

About the C (coding): entry-level algorithms test

C is a powerful general-purpose language. Since C is a middle-level language, it offers the flexibility of low-level use cases like working with kernels and drivers but also allows high-level software application development.

Strong foundational knowledge of programming in C is essential for junior programmers. Those candidates are able to hit the ground running and set themselves up for further professional growth.

This test gives candidates 10 minutes of time to complete a straightforward coding task. The code is evaluated against a set of test cases, some of which are available to the candidate to determine if they are on the right track.

This is a great initial screening test that allows you to effectively screen candidates based on essential skills.

We recommend combining coding tests with at least one of or cognitive ability tests evaluating numerical or analytical skills.

The test is made by a subject-matter expert

C as a programming language and its use in business

As a programming language, C is a popular option because it supports high and low-level languages. It is therefore considered by many developers as a base for other programming languages, seeing it referred to as a mother language.

Another of C’s notable benefits is that it can be used to create many different program types, making it a good general-purpose language. Today, C is used to develop applications, games, and operating systems like Windows. It’s also used in complex programs such as Oracle Database, Git, and Python Interpreter. In each of these programs, C enables the interaction of several entities.

C’s wide use is attributed to its machine independence, meaning that it’s not tied to any particular hardware or system. Thanks to this, developers can write programs that are not constrained to a particular type of computer.

The language’s multi-faceted nature and its many applications mean that programmers proficient in C are always in demand. This can make it difficult for recruiters to find candidates with the required level of proficiency in C.

TestGorilla’s C test can help you find the best fit for the job and recruit expert developers for your company. Let’s explain.

Recruiting with TestGorilla’s C test for entry-level algorithms

TestGorilla’s pre-employment assessment makes recruiting proficient programmers simple and fast. It takes the guesswork out of hiring and sets you and the candidates up for success.

Best used at the start of your hiring process, pre-employment testing involves evaluating job applicants on hard and soft skills. When assessing candidates, everyone will receive the same test, giving you a clear picture of how their skills compare.

Although you can use the C (Coding) Entry-level Algorithms test on its own, adding more tests to your assessment will give you a better insight into the candidates’ strengths and proficiencies. In a single assessment, you can combine a variety of tests (up to five) that not only cover the job’s technical requirements but also assess candidates’ personalities and culture-add potential.

Skills for C programmers

Using a C test to evaluate candidates’ proficiency is important to make sure they have the right level of technical aptitude for the job, but other skills are also important to the individual’s success. These include:

• Time management: Time management, or the process of planning and managing one’s time, is a crucial skill when deadlines are stringent and timelines are rigid.

• Problem-solving: This skill involves mitigating or removing obstacles that prevent the team or company from achieving its goal. Problem-solving is critical to programming because software developers often encounter code issues that they need to investigate and approach creatively to implement a successful solution.

• Critical thinking: Critical thinking involves analyzing the information available, planning an effective course, and taking action. Applicants with strong critical-thinking abilities can identify the pros and cons of different approaches and use the available data to make the right decision.

• Communication: As a skill, communication determines how individuals exchange ideas and information with others, understand their roles and workplace requirements, and how to go about communicating about projects and task updates.

• Teamwork: Working with others is very commonplace for programmers. From relaying information to project managers and product owners, to working with QAs and other programmers to resolve issues, collaboration through teamwork is important to an individual’s success as a programmer.

To help you evaluate the above skills along with technical skills and personality and culture add, we recommend pre-employment assessments. Let’s see how they work.

How pre-employment assessments work

A pre-employment assessment is a collection of tests that evaluate job applicants on hard and soft skills. The tests are chosen by the recruiter or hiring manager in alignment with the requirements for the job. This selection of tests is called an assessment.

Once you put together an assessment, we recommend that you send it to job applicants ahead of the interviewing process to help you decide which candidates should move forward to the next stage. The goal of a skills assessment is to help you identify the individuals who have the required skills for the position. Using a C test alongside other tests to evaluate applicants’ skills gives you an unbiased view of individual strengths.

What is the difference between an assessment and a test?
An assessment is the total package of tests and custom questions that you put together to evaluate your candidates. Each individual test within an assessment is designed to test something specific, such as a job skill or language. An assessment can consist of up to 5 tests and 20 custom questions. You can have candidates respond to your custom questions in several ways, such as with a personalized video.
Can I add my own questions to an assessment?
Yes! Custom questions are great for testing candidates in your own unique way. We support the following question types: video, multiple-choice, coding, file upload, and essay. Besides adding your own custom questions, you can also create your own tests.
How do video questions work?
A video question is a specific type of custom question you can add to your assessment. Video questions let you create a question and have your candidates use their webcam to record a video response. This is an excellent way to see how a candidate would conduct themselves in a live interview, and is especially useful for sales and hospitality roles. Some good examples of things to ask for video questions would be "Why do you want to work for our company?" or "Try to sell me an item you have on your desk right now." You can learn more about video questions here.
Can you explain how the other custom question types work?
Besides video questions, you can also add the following types of custom questions: multiple-choice, coding, file upload, and essay. Multiple-choice lets your candidates choose from a list of answers that you provide, coding lets you create a coding problem for them to solve, file upload allows your candidates to upload a file that you request (such as a resume or portfolio), and essay allows an open-ended text response to your question. You can learn more about different custom question types here.
Can I customize an assessment with my company logo and color theme?
Yes! You can add your own logo and company color theme to your assessments. This is a great way to leave a positive and lasting brand impression on your candidates.
What type of support do you offer?
Our team is always here to help. After you sign up, we’ll reach out to guide you through the first steps of setting up your TestGorilla account. If you have any further questions, you can contact our support team via email, chat or call. We also offer detailed guides in our extensive Help & Inspiration Center.
What is the cost for using the C (coding): entry-level algorithms test?

Can I combine the C (coding): entry-level algorithms test with other tests?
Yes. You can add up to five tests to each assessment.
Where in my recruitment process should I use the C (coding): entry-level algorithms test?
We recommend using our assessment software as a pre-screening tool at the beginning of your recruitment process. You can add a link to the assessment in your job post or directly invite candidates by email. TestGorilla replaces traditional CV screening with a much more reliable and efficient process, designed to find the most skilled candidates earlier and faster.
What kind of coding and programming tests does TestGorilla offer?
