C++ code test online

DevSkiller C++ online tests are prepared by DevSkiller’s expert team, to help recruit candidates with the right set of C++ skills. With DevSkiller, it is easier than ever to accurately assess a developer’s C++ test code, using a series of C++ assessment tests and C++ exam questions.

DevSkiller C++ test code assessments are powered by the RealLifeTesting™ methodology. This is a unique testing model based on a  simple idea that it is more useful to assess a developer based on challenges similar to the work they will face, than to set them algorithmic tests for instance, that only prove their ability at tackling algorithmic tests.

Through a series of interview questions and simulated real-life challenges, DevSkiller is able to accurately assess each candidate’s C++ test code and allow recruiters to filter the best applicants for the job from the get-go.

What to look for in C++ test code engineer

C++ is a programming language that has been around for a long time. It doesn’t always get the attention that other languages get, but it is still integral to a fair share of gaming and embedded technology. C++ is different to the C programming language, although it was originally derived as a follow-up to that language. There can often be a steep learning curve when it comes to C++ so it is important to hire the right person.

Firstly C++ interview questions will need to be tailored to refer specifically to C++ and not any other language, as there are concepts that make sense only in relation to the C++ sphere.

Your C++ candidate will then need to demonstrate knowledge in 5 main areas;- C++ libraries, compilers, debugging, code instrumentation, and static analysis.

Other than the standard library, your C++ engineer should know Boost, QT, and STL, as well as other less common, but still popular libraries, like Eigen and Loki.

Your C++ engineer will need to be familiar with the various compilers used to create applications using C++, including GCC – GNU, Clang, MSVC (Microsoft’s compiler), and ICC (Intel’s compiler). They will also need to demonstrate knowledge of the C++ debugger tools used to find bugs in C++ programs, like Valgrind, GDB, LLDB, and WinDBG.

Your C developer candidate will need to know about Address, Memory and UndefinedBehavior Sanitizer. They should also be comfortable with using debugging tools such as Address/Memory/UndefinedBehavior Sanitizer. You will also want your engineer to display knowledge of static analysis to be able to analyze the source code in terms of bugs.

Finally, it will be useful if your C++ developer is experienced in commercial and open-source projects.

Want to get more from DevSkiller C++ test code assessments?

The DevSkiller online task wizard comes ready-prepared with default C++ assessment tests, but you can also build your own fully customizable tests to get more out of them. DevSkiller is designed to be as user friendly as possible to non-technical recruiters, so the hard work is already done for you. If you do have someone technical available, then you can define the parameters of your tests. This allows you to alter the time-limit allocated for each test, to set the scope of the tests, and even to set the language being tested. All while monitoring candidates in real-time. Finding your next C++ engineer has never been easier.

Want proof that our C++ test code assessments work?

It is perfectly understandable to be interested in what DevSkiller has to offer, while also still being a little apprehensive. If you’re unsure, take a look at what some of our satisfied customers have to say:

Jonatan Rugarn - CEO, Gründer, Recruiter bei Lingonberry Talent Acquisition, Engineering Manager bei Avinode Group

"Die Dauer des Einstellungsverfahrens hat sich nicht verändert, aber wir wenden weniger Zeit und Mühe pro Bewerber auf. Außerdem verschwenden wir keine Zeit mit den falschen Kandidaten."

Michael Gerwig - Technischer Leiter bei Ada Health

"DevSkiller hat uns geholfen, kostbare Zeit vor Ort für Bewerber einzusparen, die wahrscheinlich schon geeignet sind. Wir sparen 3 Stunden pro Bewerber - das war die Zeit, die wir vorher mit Bewerbern für eine technische Aufgabe verbracht haben."

Häufig gestellte Fragen

What do you do about plagiarism?

DevSkiller takes plagiarism very seriously. As a recruiter, it is important to know that the results you are seeing for each C++ assessment test are accurate and fair. DevSkiller has a number of tools in place to ensure there can be no plagiarism during testing. Screen recording is in place to check if the candidate is looking at a different screen when taking a test and social listening tools are applied which check the candidate’s IP address and use live pair notifications. Plagiarism checks are also carried out on each candidate’s entered code and on the answers they provide to various C++ exam questions. Answers are then cross-referenced against every other answer ever provided to make sure there are no repeat answers.

Was halten die Bewerber von den DevSkiller-Tests?

The feedback we receive from developer candidates is overwhelmingly positive and most are huge fans of the structure of our C++ code test assessments. So often developers are assessed on academic algorithmic tests that they probably haven’t touched in years, whereas DevSkiller offers them a chance to demonstrate the skills they actually use on a daily basis. The fact that DevSkiller tests use normal coding tools and conventions like unit testing, and cloning to GIT from a personal IDE, is also a plus. Occasionally candidates can be a little apprehensive because they expect DevSkiller testing to be the same as algorithmic tests. Usually, once they realize the difference, candidates relish having the opportunity to prove their skills in a fair setting.

Wie legen die Bewerber einen Test ab?

DevSkiller C++ test code assessments can be taken remotely when it is convenient for the candidate. Once they have the test invite, the candidate has a set amount of time to complete their C++ assessment test. During testing, candidates can use our state of the art in-browser IDE or complete the project on their favorite IDE and then clone the project to GIT. During the test, candidates can run unit tests to ensure their solutions are working the way they’re supposed to.

Default settings limit each test to an allotted amount of time and if a candidate runs out of time, the test is automatically evaluated. Automatic reports are then sent to the recruiter once they are generated into an easy to understand, non-technical report.
