What to look for in an SQL developer
SQL is a 4th Generation Programming Language (4GL). Basically, this means that programmers only declare what the result looks like, rather than how the database should calculate the result. SQL uses more general-purpose programming languages like Java to access data from central databases.
The right SQL candidate should possess a good knowledge of SQL, including the subtleties and the nuances of its performance. They should possess skills in SQL design and relational theory. Finally, any demonstrable skills in SQL refactoring will come in handy in larger teams where the SQL is more complex.

Want proof that our SQL developer interview questions and tests work?
If you think our screening tool sounds great, but you’re a little unsure. No problem. Some of our past clients felt the same way as you, to begin with. Read the following case study to learn how we helped them:
Ada is a global health company. Their core system connects medical knowledge with intelligent technology to help people manage their health and for medical professionals to deliver effective care.
The company requires skill in technologies such as Kotlin, Java, React Native, and many more. Previously Ada screened technological skills through an on-site task, followed by a team interview. The whole procedure was laborious and time-consuming so they enlisted DevSkiller’s help.
Thanks to DevSkiller, Ada ar now able to gain a broader understanding of each candidate’s experience from an initial technical task, which is carried out prior to interviews taking place. Evaluation for DevSkiller testing is automated, which saves countless hours of time for Ada’s recruitment employees.
Michael Gerwig – Engineering manager at Ada Health
“Not only do we save a considerable amount of time, but the tool also gives us the possibility to collaborate on reviewing the technical test. It also enables us to tailor the on-site experience towards the candidate, for example, which areas to focus on or how difficult the questions should be. Overall, the feedback has been quite positive. Candidates especially enjoy the Code Review task.”
Frequently asked questions
Do I need to be a programmer to use DevSkiller?
Don’t worry, you’re not expected to be a technical expert yourself to be able to use DevSkiller. Our own experts have created ready-to-use SQL developer interview questions and tests which are specially designed to be easy for recruiters to get the best out of. This means you can verify the technical skills of the candidates screened regardless of your own level of technological skill. You can prepare a test from scratch if required.
What do you do about plagiarism?
You need to be able to trust your results, so at DevSkiller we take plagiarism very seriously. We employ a number of anti-plagiarism tools designed to catch any cheats in the act. We can implement screen recording to check if the candidate is looking at a different screen when undertaking a test, as well as a range of social listening tools. We can also check the candidate’s entered code, question duration, and the way each question was answered. Our database stores answers previously provided, which are cross-checked against new answers coming in. If there is a match it will flag that the candidate has tried to gain an unfair advantage.
How do candidates respond to DevSkiller SQL developer interview questions and tests?
We have received regular feedback from developer candidates that they love the structure of our SQL developer interview questions. It is important to understand that more often than not, developer testing involves candidates having to recite coding patterns and algorithms. This can frustrate developers because this doesn’t assess their actual development skills and could result in a lesser skilled developer progressing, simply because they happen to remember a coding pattern. We don’t leave anything to chance. Our SQL developer interview questions and tests challenge candidates with tasks exactly like the work they’ll be doing.
In turn we hear that candidates relish having the chance to use normal coding tools and conventions like unit testing, and cloning to GIT from a personal IDE. We give developer candidates a chance to demonstrate what they can really do within a fair setting and for that they are thankful.
What is the test duration?
The duration of our SQL developer interview questions and tests is flexible. Duration can be set to your own preferences if required. We provide default settings which can be altered. It is also possible to set time limits for individual questions within a test.
