Kotlin interview questions and online tests were prepared by our specialized team of professionals. We have a range of Kotlin coding tests for junior, middle, and senior-level developers.
DevSkiller Kotlin interview questions are powered by the RealLifeTesting™ methodology. This methodology is completely unique because it tests the candidate’s skills through real-world problems rather than algorithmic puzzles or riddles. Finding your next Kotlin developer is easy with DevSkiller and our Kotlin online tests.

DevSkiller Kotlin coding tests are powered by the RealLifeTesting™ methodology. The methodology works by asking candidates to answer questions and solve problems that they would have to deal with in the real world. Gone are the days of reciting old code or solving academic algorithmic puzzles. This method of testing will provide true and objective insight into your candidate’s skills. Learn more about your candidate’s coding skills, critical thinking, and time-management skills with Kotlin interview questions and online tests.
Kotlin was first released in February 2016. It is an open-source statically typed programming language that targets JVM, Android, JavaScript, and Native. Kotlin is a concise programming language and has both object-oriented and functional constructs. It can be used for any kind of development – server-side, client-side, and Android. The programming language is inspired by other existing languages such as Java, C#, JavaScript, Scala, and Groovy.
Kotlin is one of the most in-demand languages today. Java and Kotlin’s interoperability means that a background in the popular Java will serve your Kotlin candidates well. It’s also important to verify the candidate’s knowledge of Kotlin’s safety features, most notably their understanding of ‘null-safety’. Finally, any previous work in developing Android mobile or web applications is a good sign for your Kotlin developer candidates.
Do you want to build your own custom tests? No problem. The DevSkiller task wizard lets you build custom tests using your own codebase. You can select the languages, skills, and technologies you want to test. Then, choose the scope, difficulty, and test duration all while observing in real-time. Finding your next Kotlin developer has never been easier with DevSkiller and our Kotlin coding tests and interview questions.
Interested in sending your first Kotlin coding test invitation but still not 100% convinced? That’s fine, we understand that making any financial commitment for your company is a big decision. Instead of listening to us, why not listen to what one of our many satisfied customers has to say:
CodeValue:
CodeValue is a dynamic software development, UI/UX design, and consulting services firm. Before switching to DevSkiller, their screening process consisted of a phone interview with HR followed up with a technical phone interview then a test and technical interview. After that, there was still another interview with HR and the hiring manager before an offer was made. The biggest obstacle they wanted to overcome was the number of unnecessary technical interviews that took place. Once CodeValue successfully implemented DevSkiller, they were able to reduce the time to hire by approximately 50% while hiring 2.8x more developers from the same candidate pool.
“DevSkiller is easy to use and friendly.” – Olga Berger – Lead recruiter & sourcing specialist at CodeValue
Plagiarism is taken very seriously at DevSkiller and as such, we have a number of robust anti-plagiarism tools in place to ensure all test results are accurate. Screen recording to check if the candidate is looking at a different screen when undertaking a test. We also use a range of social listening tools, check the candidate’s IP address, and use live pair notifications. Our plagiarism detector checks the candidate’s entered code, question duration, and the way each question was answered. All of the answers are automatically cross-referenced with every answer that has ever been logged in our system. If there is a match between your candidate’s answer with another that has been logged, then it will be flagged and we can categorically confirm that the answer was plagiarized.
The duration of tests is flexible. We have a number of pre-defined Kotlin coding tests that have a set duration. Alternatively, you can opt to write your own tests or set the time limit of individual questions within a test.
We made DevSkiller as simple and as automated as it can possibly be. Our ready-to-use tests prepared by IT experts allow non-technical users to verify the technical skills of the candidates screened. If you have a technical person on-site, you can prepare a test from scratch.
Sending your first Kotlin coding test can be done in as little as five minutes. Our wide selection of junior, middle, and senior-level Kotlin online tests means that you can start testing your candidates right after you set up your account.
