Scala interview questions and tests

While some HR managers are screening their candidates using paper or whiteboard tests, these tests shouldn’t be treated as valid indicators of future performance. In order to assess coding skills, you need an objective, repetitive process based on tests mirroring the first day of work as closely as possible. Choose the DevSkiller Scala interview questions and tests and test your candidates remotely.

There are many features you may find useful. For example, you can ask your candidate to take a picture of themselves to be sure that that they are not cheating. Also, you can have an online interview right on the platform using the code pair feature, which allows you to get a feeling of what it’s like to work with your candidates.

The Scala interview questions and tests are developed by top experts in the Scala programming language. This means that they’re designed specifically to check the competence of your candidates in that particular language.

Wat te zoeken in een Scala ontwikkelaar

It can be incredibly difficult to find a good Scala developer. This is because the language has a more complicated syntax than Java or C#, resulting in a particularly steep learning curve that can put many developers off.  Our Scala interview questions and tests will go a long way to helping you in that regard, but it will be very helpful if you know what to look out for.

Scala is a general-purpose programming language providing support for functional programming and a strong static type system. It is mainly used in the backend development of concurrent applications. The key advantages of Scala over other languages are that it is much less error-prone and can perform more kinds of tasks than languages with more basic type systems. While other languages only work with one or two programming styles, Scala works with all three- functional, object-oriented, and imperative programming. This means that a developer working only with Scala can perform more types of tasks without having to switch to a different programming environment.

Scala uses the same runtime environment as Java, meaning a developer can use Scala libraries for Java applications and Java libraries for Scala applications. This gives Scala developers a huge advantage over other developers because they can access the incredibly large and diverse Java ecosystem.

To find a good Scala developer you are really looking for the elite. Due to its complexity, Scala developers often possess official certificates to prove their aptitude in the language.

Otherwise, you can expect a good Scala developer to know about pattern matching, as Scala has a built-in general pattern-matching mechanism. They should also possess knowledge of case classes, which are unique to Scala.

Due to Scala’s compatibility with the Java libraries, your Scala developer should be familiar with the Java open source libraries and be able to tell you which ones they prefer to use. They should also be able to show commercial experience they have gained within the past 2 years and be able to describe the technologies in which they have a functional working knowledge.

Want to customize Scala interview questions and tests?

DevSkiller Scala interview questions and tests are completely adaptable and can be customized to suit your company’s requirements. Our tests come programmed with default settings, but if you want to go one further, you can choose the programming language being assessed and the amount of time each test will take to complete. All while monitoring tests in real-time.

Want proof that our Scala interview questions and tests work?

Knowing the best way to invest your business’s money can be a heavy burden, particularly if you’re not personally familiar with the ins and outs of technical development. Don’t take our word for it, have a look at what our clients have to say:-

Richard Williams - VP van engineering bij Plutora

"Dankzij de automatisering van de screeningfase konden we het interviewpercentage met 50% verlagen. Tegelijkertijd is de kwaliteit van de kandidaten die de interviewfase halen nu veel hoger. DevSkiller voegt een extra laag van kwaliteit toe aan ons technische wervingsproces."

Olga Berger - Lead Recruiter & Sourcing Specialist bij CodeValue

"DevSkiller is makkelijk te gebruiken en vriendelijk."

Victoria Cyczewska - Talent Acquisition Specialist bij Stepstone Services

"We beschikken nu over een tool waarmee we niet alleen kunnen samenwerken om tests op te stellen voor de beoordeling van technische vaardigheden die we nodig hebben om te groeien, maar ook om intern en extern (met kandidaten) te communiceren. Bovendien is ons technisch rekruteringsproces nu meer gestructureerd. Zo gebruiken we bijvoorbeeld de resultaten van onze technische screening als conversatiestarter tijdens technische interviews."

Vaak gestelde vragen

Wat is RealLifeTesting?

De RealLifeTesting methodology is the foundation of our Scala interview questions and tests. The program is designed to simulate the kinds of real, everyday scenarios that a Scala developer would likely encounter in their daily work. This unique form of developer testing allows recruiters to gain a comprehensive understanding of an applicant’s skill set. The weaker candidates will be identified and eliminated. Only those most adept are able to demonstrate the understanding and knowledge required to be able to progress through to the next stage.

Hoe lang duurt het om DevSkiller op te zetten?

Setting up DevSkiller Scala interview questions and tests takes no time at all. Once you have created your account, tests can be ready to send out to candidates in as little as 5 minutes. DevSkiller’s database stores an extensive library of Scala interview questions, meaning all you need to do is send out the test invites.

Wat doe je tegen plagiaat?

We want to be sure that our results can be trusted. The advantage of the DevSkiller model is that our Scala interview questions and tests are assessed automatically. The DevSkiller testing platform implements strict anti-plagiarism tools to ensure test authenticity. Various checks can be carried out, including screen tests to see if the candidate is looking at a different screen while carrying out their test. DevSkiller can also automatically cross-reference the code each candidate has entered with answers given by previous candidates to see if there is a match.
