How our NoSQL interview questions work

DevSkiller NoSQL interview questions are powered by the RealLifeTestingTM methodology. Unlike other coding tests, RealLifeTestingTM works by presenting candidates with a simulated version of their real working environment and then sets them challenges to overcome within that simulation. This is revolutionary in developer testing. Implementing RealLifeTestingTM into our NoSQL interview questions means DevSkiller can offer recruiters an in-depth analysis of how each candidate is likely to perform within the role, from as early as the initial screening stage.

Our NoSQL interview questions assess a candidate’s coding skills, problem-solving ability, and time-management skills.

What to look for in an NoSQL developer

SQL is the most popular 4GL (Fourth Generation Programming Language) and nowadays is often embedded in other, more general-purpose programming languages like Java, in order to access data from central databases. While our NoSQL interview questions can go a long way to helping you work out who is the best candidate, it is helpful to at least know a little bit about NoSQL and what you are looking out for.

Becoming a NoSQL developer requires a special mindset and a special set of skills. While basic tasks can be carried out easily, performing more complex tasks in NoSQL can be harder to get right.

A good knowledge, or at least a grasp of the basics of set theory is very important in NoSQL, as it allows developers to perform bulk operations on entire data sets, directly in the database. This can have a big impact on performance.

NoSQL has evolved a lot during the past decades and various features have been implemented to make a NoSQL developer’s life easier. Knowledge of features like window functions and CTE will set the beginners apart from the seasoned pros in this area and is important in ETL, reporting, BI, and analytics use-cases.

The vast majority of NoSQL performance-related issues can be solved with proper indexing.

Being able to identify situations where an index will be beneficial, or sometimes detrimental, is essential for any good NoSQL developer.

"La durata del processo di reclutamento non è cambiata, ma spendiamo meno tempo e meno fatica per ogni candidato. Inoltre, non perdiamo tempo con i candidati sbagliati".

Domande frequenti

How do candidates take a NoSQL test?

The first thing to know is Devskiller’s NoSQL interview questions are that they can be accessed remotely and taken from anywhere in the world. This can save you countless hours of in-house testing. Candidates receive their test links via email and can start them whenever they are ready. Time limits are added to the tests and expiration times can even be added to the links themselves to make sure recruiters aren’t left waiting.

For the tests themselves, candidates have the option of using our state of the art in-browser IDE, or to complete the project on their favorite IDE and then clone the project to GIT. They can also run unit tests to check their solutions work the way they are supposed to. Candidates are assessed on their coding skills, time management, and critical thinking. Once completed tests are automatically evaluated and a report is sent to the recruiter.

Quanto tempo ci vuole per configurare DevSkiller?

DevSkiller is a real time-saver when it comes to recruitment. Not only do our NoSQL interview questions greatly increase the efficiency of the screening process, but they are also remarkably easy to set-up. Our task wizard comes prepared with tests that are ready to send out, meaning all you have to do is create your account to be able to start testing candidates in as little as 5 minutes.

What do candidates think of DevSkiller NoSQL interview questions?

We receive regular feedback about our NoSQL interview questions from developer candidates that they love the structure of our tests. Developers get tired of their skills being tested using algorithmic assessments that don’t accurately reflect the work they actually do. DevSkiller testing is different and developer’s appreciate having the chance to prove their software development skills. If any are apprehensive, to begin with, we usually find it is because they are expecting our testing method to be similar to those frustrating algorithm tests they have grown used to taking. Once they realize our tests are different, the reaction is usually very positive.

Candidates also like the fact that DevSkiller tests use normal coding tools and conventions like unit testing, and cloning to GIT from a personal IDE. Overall, candidates appreciate the opportunity to prove their skills in a fair setting where, if they have the right skills, then they should have no difficulty progressing to the next stage.
