How our Kotlin online tests work

The RealLifeTesting™ methodology is behind our Kotlin online tests. This technology works by presenting candidates with a simulated reality and then challenging them with the actual problems they are likely to face in the role. Testing is multifaceted and designed to task the candidates in various different ways. The result of which being that recruiters can pinpoint the exact strengths and weaknesses of each candidate. They can gain valuable insight into a candidate’s coding skills, their ability to problem-solve, and to their capacity to thrive under pressure.

What to look for in a Kotlin developer

Kotlin is an open-source, statically typed programming language that has both object-oriented and functional constructs. It was first released in early 2016.

Kotlin can be employed in various types of development including server-side, client-side, and Android. It is inspired by other programming languages like Java, C#, JavaScript, Scala, and Groovy.

In recent years Kotlin has become a very popular language and Kotlin developers are now amongst the most sought after. Your developer should demonstrate detailed knowledge when it comes to Kotlin. This includes knowledge of Kotlin’s safety features, most notably their understanding of ‘null-safety’.

Other than proficiency in Kotlin itself, you will want to recruit a candidate with expertise in Java, because the two languages are closely connected. Finally, any previous work in developing mobile or web applications using Android will be a bonus.

Ofte stillede spørgsmål

Hvad er RealLifeTestingTM?

RealLifeTestingTM is at the very heart of our Kotlin online tests. It is a way to go beyond traditional developer testing using algorithms, to a place where recruiters can accurately assess exactly how well each candidate has performed. It uses technology to present candidates with realistic challenges and then assesses their knowledge on a deeper level than was previously possible.

Developers are required to demonstrate considerable ability when it comes to coding ability and code cleanliness, resources like Stack Overflow, decision making, and critical thinking. The candidates who progress are those that have performed well under scrutiny.

How do candidates take a Kotlin online test?

From anywhere in the world, as soon as a candidate is ready they can begin taking their Kotlin test. Recruiters are also welcome to observe the tests being taken in real-time during the process.

Test links are only active for a short while, giving the candidate only a small window in which to work. The tests last until the candidate is finished. If the candidate does not complete their test, then it expires when the allotted time-elapses.

While working, candidates have two options- to use DevSkiller’s state of the art in-browser IDE, or to complete their project on their favorite IDE and clone the project to Git. Much like in their real work, candidates can build the project and run unit tests throughout, to make sure their solutions work.

How are Kotlin online tests evaluated?

Our expert team has designed our developer tests to be as automated as possible, taking the strain off recruiters. With our Kotlin online tests, once the candidate is finished, the DevSkiller platform automatically begins the evaluation process. The platform works out exactly how well each candidate has performed in various areas of testing. Results are then added to a non-technical report that breaks down how well each candidate has performed, including whether their solutions would work. Strict robust plagiarism features ensure recruiters can trust the results they receive.
