Screen candidates with the highest quality 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.

How we design questions

Test candidates on core Grails Hiring Test topics

Grails Commands: Grails commands are a set of predefined actions that can be executed from the command-line interface. They provide tools for creating, modifying, and managing Grails applications. Measuring this skill helps assess a candidate's familiarity with the command-line interface and their ability to perform common development tasks efficiently.

Grails Controllers: Grails controllers handle incoming requests and generate responses in a Grails application. They bridge the gap between the user interface and the underlying business logic, making them a crucial component to test. Evaluating this skill assists in determining a candidate's understanding of how to handle HTTP requests, process data, and manage the flow of an application.

Grails Filters: Grails filters allow developers to add pre- and post-processing logic to requests and responses. They provide a way to implement cross-cutting concerns like authentication, authorization, logging, and caching. Assessing this skill helps gauge a candidate's ability to write and configure filters effectively to improve the functionality and security of a Grails application.

Grails GORM: Grails Object Relational Mapping (GORM) is a powerful feature that simplifies the management of persistent data in a Grails application. It provides a high-level API for defining and interacting with domain objects, and handles the underlying database operations transparently. Measuring this skill allows recruiters to assess a candidate's understanding of database integration and their ability to design and execute database operations effectively.

Grails Domain Classes: Grails domain classes represent the business entities in an application and define the structure of the underlying data model. They encapsulate properties, relationships, and validation rules. Assessing this skill helps evaluate a candidate's proficiency in defining and utilizing domain classes to ensure data integrity and consistency.

Grails GSP: Grails Server Pages (GSP) is a template engine used for generating dynamic web content in a Grails application. It resembles HTML but includes server-side tags and logic. Evaluating this skill allows recruiters to measure a candidate's ability to create visually appealing web pages, handle data rendering, and implement reusable components efficiently.

Database Integration: Database integration is the process of connecting and interacting with a database within a Grails application. It involves configuring the application to communicate with the database, performing CRUD operations, and managing database connections and transactions. Measuring this skill helps assess a candidate's ability to effectively use database technologies and handle data persistence in a Grails application.

Plugins: Plugins are modular components that extend the functionality of a Grails application. They provide reusable features, such as authentication, logging, and caching. Evaluating this skill helps determine a candidate's knowledge of plugin utilization, which is crucial for leveraging existing solutions and accelerating development.

Data Binding: Data binding is the process of mapping incoming request data to objects or variables in a Grails application. It helps automate the handling and validation of user input. Measuring this skill assists in assessing a candidate's ability to bind and validate data effectively, preventing security vulnerabilities and ensuring data consistency.

Have questions about the Grails Hiring Test?

How does pricing work?

You can check out our pricing plans.

Can I customize the test?

Yes, absolutely. Custom assessments are set up within 48 hours 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. You can also customize a test by uploading your own questions.

Can I combine multiple skills into one test?

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.

What roles can I use the Grails Assessment Test for?

Here are few roles for which we recommend this test:

  • Groovy on Grails Developer
  • Grails Software Developer
Can I see a sample test, or do you have a free trial?


The free trial includes one sample technical test (Java/ JavaScript) and one sample aptitude test that you will find in your dashboard when you sign up. You can use it to review the quality of questions and the candidate experience of giving a test on Adaface.

You can preview any of the 500+ tests and see the sample questions to decide if it would be a good fit for your requirements.

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.

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.
