How DevSkiller Scala interview questions and tests work
Our Scala interview questions are powered by the RealLifeTesting™ methodology, a uniquely designed testing system set up to replicate the real working environment of a Scala developer. Developer candidates are presented with challenges based on the kinds of work they usually encounter every day. This allows recruiters to accurately assess a candidate’s time-management skills, problem-solving ability, and Scala coding skills, all during the initial screening stage. DevSkiller testing is efficient, time-saving, and cost effective, and can save your company countless hours of in-house testing.
- Test Scala coding ability and not just academic ability
- リアルライフテスト™ methodology offers a unique testing platform where candidates can opt to use their own IDE, clone to Git, run unit tests, and access Stack Overflow, Github and Google for research.
- Tests range from senior level developer down to junior Scala developer positions.
Skills covered in our Scala interview questions and tests
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.
