What to look for in C and C++ developer

C++ is a multi-paradigm language that excels in procedural and object-oriented programming, as well as being a practical choice for functional programming. 

C and C++ are not the same, but a C++ developer will need to have many of the same attributes as a C developer. The first attribute is possessing an understanding of pointer arithmetic and what constitutes undefined behavior. Your developer should also be comfortable with using debugging tools such as Address/Memory/UndefinedBehavior Sanitizer, Valgrind, debuggers (e.g. GDB), and static code analysis tools. What sets the C++ developer apart from a C developer is, in addition they also need to be able to understand Boost and Qt libraries sufficiently enough to be able to use them. 

To make sure you have the right candidate for your business, you will also want your CPP developer to be experienced in commercial and open-source projects.

It is understandable to be a little hesitant when investing your company’s money, so don’t take our word for it, check out the case study below and read what some of our satisfied customers have to say.

Lingonberry is a Talent Acquisition company. Before they enlisted DevSkiller’s help, their recruitment process was inefficient and time-consuming. Their recruiters found it difficult to filter applicants during the screening process. Half of the candidates Lingonberry assessed, were invited back for a technical interview and 15 candidates had to be interviewed in order to make just two hires. Also, recruiting for any higher positions was very difficult, as the Lingonberry recruiters were required to be competent at that level, in order to accurately assess which candidates possessed the skill-level required.

By introducing DevSkiller testing Lingonberry was able to eliminate 50% of their candidates before the interview stage, saving time and money during the recruitment process. Lingonberry can also now accurately recruit senior positions in which they have limited in-house expertise and still ensure they select the right applicant for the role.

"A duração do processo de recrutamento não mudou, mas gastamos menos tempo e esforço por candidato". Também não perdemos tempo com os candidatos errados".

Micha Gerwig – Engineering manager at Ada Health

"O DevSkiller ajudou-nos a poupar tempo precioso no local para os candidatos que já estão em condições de se adaptar". Estamos a poupar 3 horas por candidato - esse foi o tempo que gastámos com candidatos numa tarefa técnica antes".

Magdalena Rogóż - Gerente de Marketing Adjunto na Kodilla

"Usar o DevSkiller para classificar os testes é 2 vezes mais rentável, ao mesmo tempo que dá aos nossos alunos um teste muito melhor e os prepara para futuros testes de recrutamento".

Perguntas mais frequentes

Quanto tempo demora a montar o DevSkiller?

DevSkiller C and C++ tests take no time at all to set up. You can be testing applicants within 5 minutes. Devskiller comes ready with an extensive library of C and C++ tests, meaning the hard work is already done for you.

How do candidates take a C and C++ test?

Applicants are sent a test invite which they can access remotely and begin their test wherever and whenever is suitable to them. They can use their preferred IDE and then clone the project to GIT, or they can opt to use our state of the art in-browser IDE. During the test, candidates can even run unit tests to ensure their solutions are working the way they’re supposed to. Automatic reports that are easy to understand, even for non-technical minds, are then sent to the recruiter with the results.

How are C and C++ tests online evaluated?

Once the candidate completes their test or the time elapses, the DevSkiller platform begins automatically evaluating the results. Candidates are assessed on the quality of the coding and if there are any errors in the code, whether or not the solutions they came up with would run (an essential factor in all software development) and how their code stands up in edge cases. Stringent anti-plagiarism tools ensure the validity of test results.
