We have coding tests available for a range of roles and positions at every level. Without naming all of them, here are just a handful of positions you can test for with our code tests:
All DevSkiller coding tests are powered by the RealLifeTesting Methodology™. This form of testing is totally unique to DevSkiller and provides valuable insight into the candidate’s skills. It works by testing with real-world problems and tasks that they are likely to face on the job. This methodology will not only provide a clear understanding of the candidate’s coding skills but also their critical thinking, problem-solving ability, and time management skills.
Want to start testing your developer candidates using your own codebase? No problem! With DevSkiller and our online task wizard, building your very own custom tests has never been easier. Choose the languages, resources, and skills you want to test, set the test difficulty and duration, plus loads more. Finding the right candidate today with DevSkiller and our coding test catalog.
We understand that it’s important to think carefully before making financial decisions for your company. Rather than listening to us, why not have a read about what one of our many satisfied customers have to say about DevSkiller code tests.
Plutora
Plutora is a leading player in value stream management, with release, test environment, and analytics solutions for enterprise IT. Prior to implementing DevSkiller, Plutora used phone interviews to preselect their candidates. Those who passed were invited to a technical interview which was followed by a behavioral interview. The lack of automation in this process meant that it required a lot of manual work on their side. Also, the effectiveness of phone screening was insufficient and meant many candidates progressed to the interview stages.
The decision was made to introduce DevSkiller coding tests to help automate the technical screening process, limit the number of interviews, and identify the right candidates before the interview stage. With the successful implementation of DevSkiller code tests, Plutora was able to save approximately 8 hours per candidate of their internal development team. That’s because they don’t have to spend time interviewing weak candidates.
“Thanks to automating the screening stage, we were able to reduce the interview rate by 50%. At the same time, the quality of candidates who make it to the interview stage is now much greater. DevSkiller adds an extra layer of quality to our technical hiring process” – Richard Williams - Vicepresidente di ingegneria presso Plutora
The RealLifeTestingTM methodology serves as the basis of all DevSkiller coding tests. This form of testing is unique because unlike other methods of screening like games or algorithmic puzzles, RealLifeTestingTM provides a 360-degree view of a developer’s skills. The central belief of this methodology is that the most accurate way to evaluate the developmental skills of a candidate is through work sample tests that mirror the actual work they’ll be doing on the job. DevSkiller coding tests task candidates with building full project apps or adding features to existing apps, just like they’ll be doing after being hired. To be successful, candidates must display their knowledge of coding and resources such as Stack Overflow to come up with solutions and problem solving for any issues they encounter. The results will provide insight into the candidate’s academic knowledge, coding skill, decision making, code cleanliness, and problem-solving ability.
The DevSkiller platform gets to work as soon as the candidate finishes their test. The results are automatically generated into a report that even a non-techncial recruiter can understand. Candidates are graded on whether the solution would run (an essential factor in all software development), whether or not there are any errors in the code, code quality, and how it works in edge cases. DevSkiller coding tests are also subject to a series of robus plagiarism features that compare results to previous solutions from other candidates.
DevSkiller code tests are fully remote and can be sent anywhere in the world. All the recruiter needs to do is send the candidate a test invite. DevSkiller code tests can be set to be available for a specific amount of time, for example, within 3 days. Candidates can elect to start the test at a time of their choosing, and they have the option of using our state of the art in-browser IDE or completing the project on their favorite IDE and then cloning the project to GIT. As candidates are taking the test, they can elect to run unit tests to make sure their solutions work as they’re supposed to. DevSkiller predefined coding tests have a set time limit. Once the time expires, the code test is automatically evaluated and the report is sent to the recruiter.
