FAQs

What is meant by OOPS in Kotlin?

Object Oriented programming or OOPs is a programming style that is associated with concepts like class, object, Inheritance, Encapsulation, Abstraction, Polymorphism. Most popular programming languages like Java, C++, C#, Ruby, Kotlin, etc., follow an object-oriented programming paradigm. In OOP, computer programs are designed in such a way where everything is an object that interacts with one another. The main aim of OOP is to bind together the data and the functions that operate on them so that no other part of the code can access this data except that function.

What type of questions will the Kotlin Online Test include?

The test is designed to enable recruiters and hiring managers to quickly identify which applicants should be invited to an interview. This test will assess applicants on their fundamentals and depth of Kotlin programming language with questions on OOPs, exception handling, basics of Android, implementing UI for Android applications, etc. The questions are designed to test on-the-job Kotlin skills as opposed to just theoretical concepts. The programming and debugging challenges test the problem-solving and coding ability of your candidates.

What is a custom assessment?

Every role is different and requires a custom assessment to identify top candidates efficiently. Adaface subject matter experts understand your job description/ role requirements and pick the most relevant questions from our library of 10000+ questions to create a technical assessment that helps you find the qualified candidates in your candidate pipeline quickly. All custom assessments are set up based on the job description, role requirements, must-have skills, experience level and salary range within a maximum of 48 hours and you will get an email notification once it goes live.

Check out a sample assessment here (no credit card required).

Can I combine multiple skills into one custom assessment?

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify.

How is Adaface different from other assessment tools?

We believe that status quo tech assessment platforms are not a fair way for companies to evaluate engineers because they focus on trick questions/ puzzles/ niche algorithms. We started Adaface to help companies find great engineers by assessing on-the-job skills required for a role. Read more about why we started Adaface.

Here's what's different with Adaface:

  1. High quality non-googleable questions that test for on-the-job skills as opposed to theoretical knowledge.
  2. A friendly conversational assessment with a chatbot, instead of sending a "test" to a candidate. This translates to a higher completion rate. Adaface assessments (86% candidate completion rate), as opposed to traditional tests (40-50% candidate completion rate)
  3. Customized assessments for 700+ skills at different experience levels.
Do you have any anti-cheating features in place?

We have the following anti-cheating features in place:

  1. Web proctoring
  2. Webcam proctoring
  3. Plagairism detection
  4. Non-googleable questions
  5. Secure browser

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. As in an assessment is optimizing 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 60%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

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.

Does every candidate get the same questions?

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 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.

I'm a candidate. Can I try a practice test?

No. Unfortunately, we do not support practice tests at the moment.

Can I get a free trial?

You can sign up for free and check out the platform here. The dashboard has a sample assessment for you to review the quality of questions and check out the candidate experience of a chat based assessment. Since our questions are premium, we are unable to share sample questions for a particular skill/ technology. You can also review our sample public questions here.

Score Distribution

You should expect ~20% of the candidates to do well on Adaface assessments.

The score distribution for our assessments follow the normal curve. This is a good sign- standardized tests like SAT and GRE follow the normal distribution (bell curve).

Status quo assessments typically have the exact opposite of the bell curve (too many candidates getting close to 0, too many candidates getting close to 100 and too few candidates in the middle). This is typically because they focus on theoretical questions or trick questions, which are very binary in nature- either you know the trick/ theory or you don’t.

About The Role

Kotlin is a cross-platform, statically typed programming language with type inference. Developed by JetBrains, Kotlin is widely used by Android developers and is designed to interoperate with Java.

Sometimes referred to as the Java alternative, the Kotlin programming language is much safer and more concise than the Java programming language. Additionally, Kotlin and Java files can coexist in the Android applications so that Kotlin is not only useful for new apps, but also for expanding existing Java applications.

This Kotlin Online Test for hiring candidates focuses on testing for on-the-job skills.

Typical Kotlin Developer responsibilities include:

  1. Designing and developing high-volume, low-latency applications with high-performance, reusable, and reliable Kotlin code.
  2. Analyzing user requirements to develop the Android libraries, services, and SDKs for client applications.
  3. Defining, develop, and maintain REST APIs and services.
  4. Translate designs and wireframes into high-quality code.
  5. Supporting users by developing documentation and assistance tools.
