How our SQL online tests work
The RealLifeTesting™ methodology powers DevSkiller SQL coding tests. Our selection of coding tests will help you analyze your applicants’ knowledge of various SQL versions. In addition to that, our coding tests will help you assess applicants’ coding skills, problem-solving ability, and time management.
- DevSkiller SQL coding tests measure applicants’ coding ability and not just their academic knowledge
- Remote testing that gives you the freedom and convenience of testing candidates from all over the world
- The RealLifeTesting™ methodology creates a better user experience where candidates can use their own IDE, clone to GIT, run unit tests and access Stack Overlow/Github/Google for research
- Strict anti-plagiarism tool that ensures accurate test results
- Automatically generated results that non-tech professionals can understand
- SQL coding tests available for junior, middle, and senior-level positions
What to look for in SQL developers
SQL is the most popular 4GL (Fourth Generation Programming Language), which means that programmers only declare what the result looks like, rather than how the database should calculate the result. SQL is embedded in other, more general-purpose programming languages like Java to access data from central databases.
A qualified SQL developer should possess well-versed abilities with SQL performance. In addition to this, your successful candidate should possess SQL design skills with demonstrated knowledge of relational theory. Finally, SQL refactoring skills can prove quite useful in larger teams where the SQL is more complex.

Want proof that our SQL online tests work?
How can you be expected to understand how effective our screening tool is if you’ve never tried it? After all, our DevSkiller SQL online tests are different to the traditional algorithmic tests you will have encountered. Don’t take our word for it, have a look at what some of our past customers have to say:
Patrycja Kiljańska – Talent acquisition specialist at Spartez
“We’ve replaced a high-maintenance in-house solution with DevSkiller. Our process looks the same, however, the product gives us better performance. The results are also way easier to assess.”
Michael Gerwig – Engineering manager at Ada Health
“DevSkiller helped us to save precious on-site time for applicants that are already likely to be a fit. We’re saving 3 hours per candidate – that was the time we spent with applicants on a technical task before.”
Jonatan Rugarn – CEO, Founder, Recruiter at Lingonberry Talent Acquisition, Engineering Manager at Avinode Group
“The duration of the recruitment process has not changed, but we spend less time and effort per candidate. We also don’t waste time on the wrong candidates.”
Frequently asked questions
How are SQL online tests evaluated?
One of the main advantages of DevSkiller testing is that evaluation of our SQL online tests happens automatically. As soon as the candidate is finished, our screening tool gets to work on the solutions and automatically assesses how well each candidate has done. This saves recruiters countless arduous hours spent marking algorithm tests.
Candidates are assessed on whether or not the solution they came up with would run (an essential factor in all software development). How their solution would perform in edge cases and the content and quality of their code. Successful candidates are those who can best demonstrate their critical thinking skills in the time allotted.
Results are then compiled into concise, easy-to-follow reports, that non-technical professionals can understand regardless of their own level of technical skill.
How do candidates take an SQL online test?
Devskiller SQL online tests are accessed remotely and can be taken from anywhere in the world. Saving valuable time spent waiting until both the candidate and the interviewer have time to conduct a test. Remote-testing means once the test invites are sent, the recruiter just has to sit back and wait for the results to come in. Recruiters can even add time limits to each test to make sure they’re not left waiting around.
When it comes to the test itself, candidates have the option of using DevSkiller’s state-of-the-art in-browser IDE or they can complete the project on their favorite IDE and then clone the project to GIT. If they want, candidates can run unit tests to make sure their solutions work the way they are supposed to.
What’s the duration of SQL online tests?
The duration of our SQL online tests is flexible and is left up to the recruiter. Each SQL test comes loaded with default settings, including a default duration, but these can be easily adjusted. Even individual questions within a test can be given time limits if required.
What do candidates think of DevSkiller SQL online tests?
Developers’ reactions to our SQL online tests are by and large, very positive. The vast majority of candidates relish the chance to prove their software development skills. If occasionally, a developer’s reaction is not as we expect, this is usually just an initial reaction to having to take the tests at all. Many developer tests don’t reflect the real work that developers actually do, so they can grow wary of developer testing. Once they realize our tests are different, they’re overwhelmingly positive in their responses and love the chance to actually show what they can do.
Our SQL online tests allow developers to use normal coding tools and conventions like unit testing and cloning to GIT from a personal IDE.
