DevSkiller NoSQL online tests are powered by the RealLifeTesting™ methodology. Analyze your applicants’ knowledge of the NoSQL database in a pre-determined test environment. Assess each applicants’ NoSQL knowledge, coding ability, problem-solving, and time-management skills.
NoSQL (often referred to as Not Only SQL) is a term for databases that do not use relations to store data. NoSQL databases vary depending on their data model. The main types are document, key-value, wide-column, and graph. NoSQL first appeared in the late 2000s when the cost of storage fell dramatically.
Your NoSQL applicant should be familiar with relational databases such as MongoDB, ZooKeeper, and Apache Hadoop. Knowledge of operating systems such as Linux, Unix, Apache, and Tomcat is also a good sign of a qualified applicant. Finally, they should be able to recognize the three camps of NoSQL data representation; document-oriented databases, graph-based NoSQL databases, and key/value databases.
Do you want to test your applicants with your own custom test? No problem. With the DevSkiller online task wizard, you can build your own fully customizable tests. Choose which languages you want to assess, allocate a time limit, and define the scope all while monitoring your applicants’ process in real-time.

We understand that making the investment in our screening tool is a big decision for every business. If you’re still unsure, just take a look at what some of our satisfied customers have to say:
“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.”
“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”
“The greatest advantage for the candidates is that they can proceed with the tests at their own convenience. In case you have a candidate who is already working and is thinking about changing the career or moving to another company, it is also a time saver for them, as they do not have to take time off in order to attend numerous interviews in the search for a new position.”
The RealLifeTestingTM methodology is the foundation of all DevSkiller NoSQL coding questions. Unlike other coding challenges or algorithmic puzzles, RealLifeTestingTM simulates real-world scenarios that your applicants would be likely to encounter. This kind of testing will provide you with a comprehensive understanding of your applicant’s skill level.
At its core, the RealLifeTestingTM stems from the belief that the best way to evaluate a developer’s development skills is with a work sample test that mirrors the actual development work they’ll do. The successful candidate should demonstrate a clear understanding and knowledge of NoSQL, display the ability to utilize resources like Stack Overflow, and possess critical thinking to determine the quickest and most efficient solution to problems they encounter.
The DevSkiller platform gets to work automatically after the candidate either completes the test or the time elapses. The results are compiled into a report that is clear and easy to understand for non-technical professionals such as recruiters or hiring managers. Candidates are assessed on whether or not the solution they came up with would run (an essential factor in all software development), the number of errors in the code, quality of the code, and how it works in edge cases. DevSkiller ensures test accuracy with our range of anti-plagiarism tools.
DevSkiller’s NoSQL online tests can be taken remotely, at the convenience of each individual candidate. All a recruiter needs to do is send out the test invite. Each test invite can be set to be available for a specified amount of time. Candidates have the option to use our state fo 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. Tests have a pre-defined time limit, and if a candidate runs out of time, the test is automatically evaluated. Reports are sent to the recruiter once they are generated.
