About the test:
The Kotlin Online Test uses scenario-based and code tracing MCQ questions to evaluate a candidate's ability to use Kotlin basics (Variables, Strings), Kotlin Collections (List, Map, Set, Iterators), and Kotlin OOPs (classes, inheritance, interfaces) to develop null-safe, concise and readable Kotlin code. The test has coding questions to evaluate hands-on Kotlin programming skills.

The Kotlin Online test helps recruiters and hiring managers identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves expensive engineering time by filtering out unqualified candidates.
The Adaface Kotlin test screens candidates for the typical skills recruiters look for in a Kotlin developer:
The Kotlin Online test is designed to test for Kotlin fundamentals and hands-on coding skills. If you would like to test Android skills, then we design a custom test to evaluate Kotlin and Android skills in the same assessment. You can review our Android test to get a sense of our Android questions.
Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.
The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.
Why we started Adaface ->We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.
These are just a small sample from our library of 10,000+ questions. The actual questions on this Kotlin Online Test will be non-googleable.

With Adaface, we were able to optimise our initial screening process by upwards of 75%, freeing up precious time for both hiring managers and our talent acquisition team alike!

The most important thing while implementing the pre-employment Kotlin Online Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.
Email invites: You can send candidates an email invite to the Kotlin Online Test from your dashboard by entering their email address.
Public link: You can create a public link for each test that you can share with candidates.
API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.
Adaface tests are conversational, low-stress, and take just 25-40 mins to complete.
This is why Adaface has the highest test-completion rate (86%), which is more than 2x better than traditional assessments.

The hiring managers felt that through the technical questions that they asked during the panel interviews, they were able to tell which candidates had better scores, and differentiated with those who did not score as well. They are highly satisfied with the quality of candidates shortlisted with the Adaface screening.
Yes. We support testing multiple skills in the same test. You can review our standard Android test to get a sense of what kind of questions will be included to test Android skills. The final test will include MCQ questions to evaluate Kotlin, Android and coding questions to evaluate Kotlin.
Yes. We design custom chat flows where a few skills can be optional. For Android roles, typically we design tests where candidates are given a choice to choose their preferred programming language between Java and Kotlin. The bot will ask questions only on the chosen programming language. The coding questions can be restricted to desired programming languages. In this case, the candidate can choose between Java and Kotlin to write the code.
Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify.
We have the following anti-cheating features in place:

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.
Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.
Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.
No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.
