DevSkiller NoSQL interview questions are powered by the RealLifeTestingTM methodology, which is the real driving force behind our testing. This methodology is completely unique and provides valuable insight into a candidate’s NoSQL skills. Each developer is tested in an in-depth manner by challenging them with real-world tasks. Finding your next NoSQL developer has never been easier thanks to DevSkiller NoSQL interview questions.
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.
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.
Maybe you think our NoSQL interview questions sound great, but you want to get more out of them. No problem. The DevSkiller online task platform allows you to build your very own customized NoSQL interview questions. Now you can choose the languages you test, as well as the difficulty and duration of the questions. Best of all, you can send test invitations to candidates all over the world. Finding your next NoSQL developer is easy with DevSkiller and our NoSQL interview questions.
It can feel like a lot of pressure making financial decisions on behalf of your company, so you need to be sure you’re making the right choice. Don’t take our word for it that DevSkiller
interview questions are the best way to screen developers, read what our customers said:
“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.”
“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 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.”
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.
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.
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.
