Scala-interviewspørgsmål og -tests

In order to assess Scala coding skills, you need an objective process based on tests that mirror the first day of work as closely as possible. DevSkiller Scala interview questions can assess your candidates accurately and remotely.

Some HR managers are still screening their candidates using whiteboard tests. These tests are outdated and shouldn’t be treated as valid indicators of performance. Automatically assessed developer testing is the future.

There are many features of our Scala developer tests 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 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.

Devskiller’s Scala coding tests are developed by experts in the Scala language. The tests are designed specifically to check the competence of your candidates.

Hvad du skal kigge efter hos en Scala-udvikler

It can be incredibly difficult to find a good Scala engineer. 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 go a long way to helping you in that regard. However, 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. It is a pure object oriented language that is similar to Java. It is a statically typed language.

The language is mainly used in the backend development of concurrent Scala 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 experts a huge advantage over other developers because they can access the incredibly large and diverse Java ecosystem.

To find a good Scala engineer 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 they’ll 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 candidate 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 and working knowledge.

Vil du tilpasse Scala-interviewspørgsmål og -tests?

DevSkiller Scala tests are completely adaptable and can be customized to suit your company’s requirements.

Vil du have bevis på, at vores Scala-interviewspørgsmål og -tests virker?

Det kan være en tung byrde at vide, hvordan du bedst investerer din virksomheds penge, især hvis du ikke selv er bekendt med den tekniske udvikling. Du skal ikke tage vores ord for gode varer, men se, hvad vores kunder har at sige:-

Richard Williams - VP of engineering hos Plutora

"Takket være automatiseringen af screeningsfasen kunne vi reducere antallet af samtaler med 50%. Samtidig er kvaliteten af de kandidater, der når frem til interviewfasen, nu meget højere. DevSkiller tilføjer et ekstra lag af kvalitet til vores tekniske ansættelsesproces"

Olga Berger - Ledende rekrutteringsspecialist hos CodeValue

"DevSkiller er nem at bruge og venlig."

Victoria Cyczewska - Specialist i talentindkøb hos Stepstone Services

"Vi har nu et værktøj, som ikke kun gør det muligt for os at samarbejde om at lave tests til vurdering af de tekniske færdigheder, som vi har brug for at udvikle, men også at kommunikere internt og eksternt (med kandidater). Desuden er vores tekniske rekrutteringsproces nu mere struktureret. Som et eksempel bruger vi vores tekniske screeningsresultater som en samtalestarter under tekniske samtaler."

Ofte stillede spørgsmål

Hvad er RealLifeTesting?

RealLifeTesting metodologi er grundlaget for vores Scala-interviewspørgsmål og -tests. Programmet er designet til at simulere den slags virkelige, daglige scenarier, som en Scala-udvikler sandsynligvis vil støde på i sit daglige arbejde. Denne unikke form for udviklertest giver rekrutteringsmedarbejdere mulighed for at få en omfattende forståelse af en ansøgers færdigheder. De svageste kandidater vil blive identificeret og elimineret. Kun de mest dygtige er i stand til at demonstrere den forståelse og viden, der kræves for at kunne gå videre til næste fase.

Hvor lang tid tager det at opsætte DevSkiller?

Det tager ingen tid at opsætte DevSkiller Scala-interviewspørgsmål og -tests. Når du har oprettet din konto, kan testene være klar til at blive sendt ud til kandidaterne på kun 5 minutter. DevSkillers database gemmer et omfattende bibliotek af Scala-interviewspørgsmål, hvilket betyder, at det eneste du skal gøre er at sende testinvitationerne ud.

Hvad gør du ved plagiat?

Vi vil gerne være sikre på, at vores resultater er pålidelige. Fordelen ved DevSkiller-modellen er, at vores Scala-interviewspørgsmål og -tests vurderes automatisk. DevSkiller-testplatformen implementerer strenge antiplagiatværktøjer for at sikre testens autenticitet. Der kan udføres forskellige kontroller, herunder skærmtests for at se, om kandidaten kigger på en anden skærm, mens han/hun udfører sin test. DevSkiller kan også automatisk krydsreferere den kode, som hver enkelt kandidat har indtastet, med svar fra tidligere kandidater for at se, om der er overensstemmelse mellem dem.
