FAQs

How is the test customized for senior and junior level developers?

Our experts customize the test based on number of years of experience you would expect from the candidates and skill level required. Based on this data, the topics picked for questions will vary for senior and junior level developers. For ex: concepts like Prototypes is usually selected for evaluating Senior developers. Once topics are decided, we also customize difficulty level of questions on each topic based on seniority. For senior developer tests, most of the questions would be of medium and hard difficulty where as for junior developer tests, it would be easy and medium difficulty.

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.

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

JavaScript (JS) is a lightweight, interpreted, or just-in-time compiled programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. About 1/3rd of all developer jobs require some JavaScript knowledge.

JavaScript developers can target more platforms than any other high level language, as JavaScript is the most popular programming language with the richest OSS module ecosystem available. It is used to create interactive webpages, user experience, and responsive front-end design. Anything a user clicks, inputs, edits, or pulls up on a website is possible. This JavaScript Online test is designed to help you find the best JavaScript engineers for your role.

Typical JavaScript Developer responsibilities may include:

  • Develop new user-facing features
  • Translation of designer mock-ups and wireframes into front-end code
  • Design and develop new front end applications for various platforms Help out with front end work on other applications (HTML/CSS/JS in Ruby applications)
  • Perform code analysis, requirements analysis, identification of code metrics, system risk analysis and software reliability analysis
  • Collaborate with back-end developers and web designers to improve usability
  • Optimize applications for maximum speed
