What to look for in NoSQL engineer
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.

Patrycja Kiljańska - Especialista en adquisición de talentos en Spartez
"Hemos sustituido una solución interna de alto mantenimiento por DevSkiller. Nuestro proceso es el mismo, pero el producto nos ofrece un mejor rendimiento. Además, los resultados son mucho más fáciles de evaluar".
Richard Williams - Vicepresidente de ingeniería en Plutora
“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”
Ivana Nikolic - Director de RRHH en ImpacTech
"La mayor ventaja para los candidatos es que pueden realizar las pruebas cuando más les convenga. En caso de que haya un candidato que ya esté trabajando y esté pensando en cambiar de carrera o trasladarse a otra empresa, también supone un ahorro de tiempo para él, ya que no tiene que tomarse días libres para asistir a numerosas entrevistas en la búsqueda de un nuevo puesto."
Preguntas más frecuentes
¿Qué es RealLifeTestingTM?
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.
How are NoSQL online tests evaluated?
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.
¿Cómo hacen el examen los candidatos?
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.
