C interview questions

At DevSkiller our expert team designs C interview questions and C online tests to accurately measure a developer’s prowess when it comes to C. We aim to help recruiters to filter down candidates until they are left with only the best developers.

Using traditional algorithm tests alone, it can be difficult to work out which developer candidates possess the desired skills for a role within any company. This is because much of what candidates are tested on does not accurately reflect the work they are expected to perform. DevSkiller C interview questions are changing this. Our C online tests use RealLifeTestingTM technology to challenge developers with tasks that accurately reflect their everyday working lives. DevSkiller testing gives you results you can trust and makes finding your next C developer easier than ever.

Recommended roles for C interview questions

  • Sviluppatore C junior
  • Middle C developer
  • Senior C developer
  • Sviluppatore di software
  • Programmatore C
  • Sviluppatore Java
  • C/C++ developer
  • Programmer analyst
  • Sviluppatore full stack
  • Ingegnere del software

How DevSkiller C interview questions work

DevSkiller’s unique differentiator is we implement RealLifeTestingTM with our C interview questions. The RealLifeTestingTM methodology uses simulations to replicate a developer’s world and then presents them with C based tasks based on that simulated reality. This allows recruiters to accurately measure a candidate’s C development skills, from the initial stages of screening.

Recruiters are able to save hours and money, by testing candidates remotely and then filtering quickly those candidates that are right for the role and those who aren’t up to the standard required. Candidates are tested on their coding, the solutions they provide to problems they encounter and their critical thinking.

Recruiters are then provided with an automatically generated report that details the performance of each candidate. This allows the recruiter to work out who to invite back to the next stages of recruitment.

What to look for in a C developer

C is a general-purpose computer programming language that dates back to 1972. C supports structured programming, lexical variable scope, and recursion, with a static type system.

Developed by Dennis Ritchie, C was originally designed for use with the Unix operating system.

The name comes from the fact that the previous language C was based on, not particularly original, was called B. By design, C provides constructs that map efficiently to typical machine instructions.

Since its incarnation C has seen various programming languages become much more widely used today. However, C still provides the basis for many of these modern language stalwarts including C#, Java, JavaScript, Perl, Python, and PHP. In fact, C is still used by modern technology giants including Facebook, Google, and Apple.

Devskiller’s C interview questions are a great way to really test a wannabe C developer’s skills. Using a series of coding challenges, you can narrow down your search until you find the right developer for your business.

Want more from our C interview questions?

Each C online test is prepared with default settings, perfect for getting started quickly. However, you can do more with our C interview questions than just the default settings.

If you have someone technical available, then you can adapt our C online tests to suit the needs of your company. Alter the allotted time for each C online test, set your own difficulty level, and even set time-limits for individual questions. All giving you greater control over your recruitment process.

We also implement real-time monitoring, which allows you to observe your candidates during testing. DevSkiller C interview questions

Want proof that our C interview questions work?

DevSkiller C interview questions are a leading tool when it comes to developer recruitment, proven to save companies time and money on in-house testing. Don’t take our word for it, read the following case study of one of clients Spartez and see for yourself how DevSkiller testing improved their business:

Spartez is a Platinum Top Vendor on the Atlassian Marketplace. The company is focused on the Atlassian and agile ecosystem, providing useful tools for Server and Cloud, as well as offering support to customers and evaluators.

Patrycja Kiljańska is the Talent acquisition specialist at Spartez. Patrycja’s team used to recruit by first screening interview candidates using an in-house screening. More than 23% of candidates passed the initial test. This made it incredibly difficult for Patrycja and her team to decide who to bring back for the next stage of recruitment. They ended up conducting far more interviews than were necessary. Add to this that each screening test they carried out took around 15-20 minutes each to evaluate and you can start to see the issues they were having.

The first thing DevSkiller did for Spartez was to begin testing and evaluating automatically. We introduced a more thorough screening process for candidates and soon Spartez found that only 10.23% of applicants were making it past the first stage of technical screening.

Soon Patrycja and her team were able to whittle down 43% more candidates during the recruitment process than they had been able to before. This meant they met face-to-face with half the amount of people they used to. They saved time, money, and a lot of arduous testing thanks to our screening tool.

Patrycja Kiljańska - Specialista in acquisizione di talenti presso Spartez

“We give everyone a chance to attempt the test. We do not assess people only by CV and years of experience, we care more about their technical skills and depth of experience.”

How are DevSkiller C interview questions evaluated?

Our C interview questions are taken remotely. As soon as the candidate is finished, the DevSkiller testing platform gets to work evaluating how they did. The evaluation takes place automatically, saving time, and taking the workload off recruiters. Our testing method simplifies the whole recruitment process and quickens developer testing.

Once the results have been formulated, an easy to read, an automated report is produced and sent to the recruiter. The report breaks down the areas the candidate excelled in and those areas in which they didn’t perform as well. Candidates are assessed based on their coding skills, their problem-solving, and whether the solutions they have provided work as intended.

For the candidate, the tests aren’t so different from the kind of work they do every day in their role as a developer, however, for the recruiter, our C interview questions provide an invaluable insight into a candidate’s proficiency.

Come si svolge il test per i candidati?

Your developer candidates will first receive a test invite online, which they can access from anywhere. Test invites can be made available for a specific amount of time if desired and candidates can start their tests whenever is most convenient for them.

During testing, each candidate can choose to work on DevSkiller’s own state of the art in-browser IDE. If they would rather use their own IDE that’s fine too. Once completed, they can simply clone the project to GIT. To ensure their solutions are working in the desired way, during tests candidates can run unit tests.

C interview questions can range in duration, depending on how long the candidate takes and the settings applied to the tests. Once the time expires or the candidate completes their test the automatic evaluation begins.

Che cos'è RealLifeTestingTM?

Test di vita realeTM is the methodology behind all DevSkiller C interview questions. It is a way to view a developer’s performance on the job before they’ve actually been hired. We simulate their usual work surroundings and then see how they react to realistic challenges in real-time. This offers recruiters a unique insight into how well each developer candidate will perform, including their skills and their shortcomings. Successful candidates of our C interview questions are those who can demonstrate a clear knowledge of the C programming language. Those who possess the coding skills, quick-thinking, and persistence needed to overcome the issues they are faced with, all within the time given.
