The test assesses candidates' ability to configure and manage Grunt tasks, use Grunt plugins to perform tasks such as compilation, minification, and linting, and integrate Grunt with other web development tools and frameworks. Other key skills that the test focuses include JavaScript programming, build automation, code optimization, web performance, and web development best practices.

Covered skills:

  • Task Configuration
  • File Compaction
  • Creating Tasks
  • Task Configuration

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.

View sample questions

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
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 Grunt 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.

What topics are covered in the Grunt Test?

  • Task Configuration

    Task Configuration refers to the process of defining and customizing the tasks performed by the Grunt framework. It involves specifying various options, settings, and configurations that determine how the tasks are executed. This skill is measured in the test to assess the candidate's ability to effectively configure and customize tasks in Grunt.

  • File Mapping

    File Mapping involves the process of mapping input and output files in Grunt tasks. It allows developers to define the source files to be processed and the destination paths for the output files. This skill is measured in the test to evaluate the candidate's proficiency in correctly mapping files in Grunt tasks.

  • File Compaction

    File Compaction refers to the process of compressing or minifying files by removing unnecessary characters, reducing file size, and improving performance. This skill is assessed in the test to gauge the candidate's ability to effectively compact files using Grunt, which is often needed for optimizing web applications and reducing load times.

  • Custom Filter Function

    A custom filter function allows developers to define their own logic for filtering files or data in Grunt tasks. It offers flexibility to include or exclude specific files based on custom criteria. Measuring this skill in the test helps identify the candidate's capability to create and apply custom filter functions in Grunt tasks.

  • Creating Tasks

    Creating Tasks relates to the process of writing and defining new tasks in Grunt. It involves specifying the desired functionality, dependencies, and configurations for the task to be executed. This skill is measured to determine the candidate's proficiency in creating custom tasks using Grunt's task system.

  • Grunt CLI

    The Grunt CLI (Command Line Interface) allows developers to run Grunt commands and tasks from the command line. It provides a unified interface for controlling and managing Grunt tasks. Assessing this skill helps evaluate the candidate's familiarity and ability to utilize the Grunt CLI effectively.

  • Task Dependency

    Task Dependency refers to the process of specifying the order and relationships between tasks in Grunt. It allows tasks to be executed sequentially or in parallel based on their dependencies. This skill is measured in the test to assess the candidate's understanding of task dependency management in Grunt.

  • Wrapper

    The Wrapper feature in Grunt allows developers to wrap tasks in a standardized structure, making it easier to define shared options, settings, and functionality across tasks. This skill is assessed in the test to evaluate the candidate's proficiency in utilizing the wrapper feature to streamline task creation and maintain consistency.

Grunt Hiring 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.
