Adaface A/B Test is the most accurate way to shortlist Data Analysts



Reason #1

Tests for on-the-job skills

The A/B Testing 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 time by filtering out unqualified candidates at the first step of the hiring process.

The test screens for the following skills that hiring managers look for in candidates:

  • Designing and implementing A/B tests
  • Analyzing data to draw meaningful insights
  • Integrating A/B testing into various systems
  • Testing web applications using A/B methods
  • Optimizing conversions using A/B testing
Reason #2

No trick questions

no trick 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.

Reason #3

Non-googleable questions

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.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment A/B Testing 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.

The A/B Testing Test makes use of scenario-based questions to test for on-the-job skills as opposed to theoretical knowledge, ensuring that candidates who do well on this screening test have the relavant skills. The questions are designed to covered following on-the-job aspects:

  • Designing effective A/B tests
  • Analyzing data to draw insights
  • Integrating A/B testing into applications
  • Testing web applications for performance
  • Optimizing conversions through A/B testing
  • Understanding statistical significance in A/B testing
  • Identifying and resolving test conflicts
  • Analyzing user behavior in A/B testing
  • Implementing A/B testing frameworks
  • Developing data-driven hypotheses

Once the test is sent to a candidate, the candidate receives a link in email to take the test. For each candidate, you will receive a detailed report with skills breakdown and benchmarks to shortlist the top candidates from your pool.

What topics are covered in the A/B Testing Test?

  • Designing A/B Tests

    Designing A/B Tests involves the creation of experiments with two or more variants in order to compare their performance and make data-driven decisions. This skill is crucial in order to optimize website design, user experience, and marketing campaigns.

  • Data Analysis

    Data Analysis is the process of inspecting, cleaning, transforming, and modeling data to uncover useful insights and patterns. In the context of A/B Testing, data analysis is essential to interpret experimental results, validate hypotheses, and determine statistically significant differences between variants.

  • A/B Testing Integrations

    A/B Testing Integrations refer to the ability to integrate A/B testing tools with other systems or platforms such as web analytics tools, customer relationship management (CRM) software, or marketing automation platforms. This skill ensures smooth data flow, accurate tracking, and enables advanced targeting and personalization.

  • A/B Testing Web Applications

    A/B Testing Web Applications involves the implementation and execution of A/B tests specifically for web-based applications or websites. This skill includes knowledge of front-end development, HTML, CSS, JavaScript, and familiarity with web analytics and tracking tools.

  • A/B Testing Conversions

    A/B Testing Conversions focuses on measuring and optimizing conversion rates, which is the percentage of visitors who complete a desired action on a website such as making a purchase, subscribing to a newsletter, or filling out a form. This skill helps businesses improve their online marketing strategies, enhance user experiences, and drive meaningful outcomes.

A/B Online Test FAQs

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. Here's a quick guide on how you can request a custom test.

Do you have any anti-cheating or proctoring features in place?

We have the following anti-cheating features in place:

  • Non-googleable questions
  • IP proctoring
  • Screen proctoring
  • Web proctoring
  • Webcam proctoring
  • Plagiarism detection
  • Secure browser
  • Copy paste protection

Read more about the proctoring features.

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. 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.

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/ 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.

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

No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.
