Qué buscar en un desarrollador Scala

Scala is a general-purpose programming language that provides support for functional programming and strong static type system. The design for Scala began in 2001 by Martin Odersky. The key advantage of Scala is that its functional, object-oriented, and can work with all programming styles.

Experienced Scala developers should have extensive knowledge of the pattern-matching system, and Scala’s uniques case classes. In addition to this, a proficient Scala developer should understand the main object-oriented patterns of Scala; Singleton, Value object patterns, and lazy initialization.

Victoria Cyczewska - Especialista en adquisición de talentos en Stepstone Services

"Ahora disponemos de una herramienta que nos permite no sólo colaborar para crear pruebas que evalúen las competencias técnicas que necesitamos para crecer, sino también comunicarnos interna y externamente (con los candidatos). Además, nuestro proceso de contratación técnica está ahora más estructurado. Por ejemplo, utilizamos los resultados de nuestras pruebas técnicas para iniciar una conversación durante las entrevistas técnicas".

Sabu Pappu - Jefe de Adquisición de Talento en Veriday

"Hemos reducido el rechazo técnico, lo cual es estupendo. Hemos visto una mejora de 25% en este punto tras la implantación de DevSkiller.

Preguntas más frecuentes

How are DevSkiller Scala coding interview questions evaluated?

Our DevSkiller Scala coding interview questions have been designed from start to finish, to be as automated and simple to use as possible, in order to take the pressure off recruiters. Our aim is to simplify the recruitment of developers and to quicken up the whole recruitment process.

With our Scala coding interview questions, once a candidate has completed their test, or the allocated time has elapsed, then the DevSkiller platform automatically gets to work on evaluating the results. Once the results are in, an automated report is produced on how well the candidate did, designed so that even the most non-technical recruiter will easily be able to understand.

Candidates are evaluated on their coding skills if they have made any errors and the quality of the code itself. They will also be assessed on whether the solutions they have provided would run (an essential factor in all software development). Robust plagiarism features are also implemented to ensure that results are verified and have not been plagiarized from previous tests.

How do candidates take Scala coding interview questions?

Our Scala coding interview questions are accessed remotely, from anywhere in the world. This is a great time-saver when it comes to recruitment testing as it means the candidate can take the test at their earliest convenience, with no waiting around.

When taking a test, candidates can use their favorite IDE and clone the project to GIT afterward. If they prefer, DevSkiller has our own state of the art in-browser IDE, which candidates can use to complete their Scala test. Recruiters can observe candidates taking tests in real-time if they like. During the assessment, candidates have the option to run unit tests to ensure their solutions are working in the required way, much like they would in their real development work.

¿Necesito ser programador para utilizar DevSkiller?

No. We have our own Scala programming experts who have designed our tests to be able to challenge expert developers, while still being simple and easy to use for recruiters who don’t necessarily know much about Scala themselves. This means you don’t have to be an expert to be able to find one for your business.

Our Scala coding interview questions are automated when it comes to evaluation and when generating progress reports for recruiters.

¿Cuál es la duración de la prueba?

All our Scala coding interview questions come ready-prepared with default settings. However, if you decide to alter the default settings, then the duration of each Scala test can be easily adjusted. For greater control, recruiters can even attach specific time-limits to each question within a test, if they desire.
