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.

How we design questions

These are just a small sample from our library of 15,000+ questions. The actual questions on this Ruby on Rails Test will be non-googleable.

What topics are covered in the Ruby on Rails Online Test?

Ruby Basics: Ruby Basics covers the fundamental syntax, data types, and operations in Ruby, allowing developers to understand and manipulate the language effectively.

Control Flow in Ruby: Control Flow in Ruby addresses how code execution is controlled through conditionals and loops, enabling developers to make decisions and iterate over data efficiently.

Looping with Ruby: Looping with Ruby entails repeating a block of code multiple times based on a specific condition, enabling developers to automate repetitive tasks and process collections of data.

Array and Hashes: Array and Hashes deal with organizing and managing collections of data in Ruby, providing developers with powerful tools for storing, accessing, and manipulating information efficiently.

Blocks and Sorting: Blocks and Sorting involve using closures to encapsulate blocks of code and applying sorting algorithms to arrange data in a particular order, enhancing the flexibility and functionality of Ruby programs.

Hashes and Symbols: Hashes and Symbols focus on using hash data structures and symbols in Ruby, facilitating efficient key-value pair management and providing a reliable means of accessing data within the language.

Object-Oriented Programming: Object-Oriented Programming (OOP) allows developers to model programs around real-world concepts using classes, objects, and inheritance, promoting code organization, reusability, and modularity.

Modules and Mixins: Modules and Mixins enable developers to modularize and share functionality across different classes in Ruby, facilitating code reuse and promoting a more organized and maintainable codebase.

Working with Files: Working with Files covers file manipulation and file I/O operations in Ruby, equipping developers with the ability to read, write, and control files, enabling interaction with the file system and external data sources.

Metaprogramming: Metaprogramming involves code that writes, modifies, or extends other code at runtime, allowing developers to dynamically create and customize behavior, enhancing the flexibility and power of Ruby applications.

MVC Architecture: MVC Architecture is a software design pattern that separates the application into three interconnected components: Model, View, and Controller, promoting code organization, separation of concerns, and maintainability in Ruby on Rails applications.

Database Integration: Database Integration encompasses the ability to connect, query, and manipulate relational databases within Ruby on Rails applications, enabling developers to store, retrieve, and manage persistent data efficiently within their web applications.

Routing: Routing is the process of defining and mapping URLs to controller actions in a Ruby on Rails application, directing incoming requests to the appropriate handlers and enabling developers to build dynamic and navigable web applications.

Authentication: Authentication deals with user identification and verification in a web application, allowing developers to control access, implement security measures, and ensure that users are authenticated before performing certain actions.

API Integration: API Integration provides the ability to connect and interact with external third-party APIs, allowing developers to consume and integrate data and services from other applications or platforms within their Ruby on Rails applications.

Have questions about the Ruby on Rails Hiring Test?

What is Ruby on Rails Test?

The Ruby on Rails Test assesses a candidate's proficiency in the Ruby on Rails framework. It is used by recruiters to evaluate skills like MVC architecture, database integration, routing, and more. This test helps ensure candidates have the required knowledge for Ruby on Rails development roles.

Can I combine Ruby on Rails Test with Ruby questions?

Yes, recruiters can request a custom test that includes both Ruby on Rails and Ruby questions. For more details on how we assess Ruby skills, check out our Ruby Online Test.

What skills are evaluated in the Ruby on Rails Test?

The test covers various skills including Ruby basics, control flow, looping, arrays and hashes, object-oriented programming, MVC architecture, database and API integration, and authentication.

How to use Ruby on Rails Test in my hiring process?

Use the Ruby on Rails Test as a pre-screening tool at the start of your recruitment. Attach the test link to your job post or send email invites to candidates. This helps identify skilled candidates early in the hiring process.

Can I test Ruby and Rails together in a test?

Yes, you can test both Ruby and Rails together. We offer a comprehensive Ruby & Rails Test that evaluates both skills. It's recommended for roles requiring expertise in Ruby on Rails.

What are the main Ruby tests?

We offer several tests for Ruby and related skills:

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:

Hidden AI Tools Detection with Honestly
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.

What is the cost of using this test?

You can check out our pricing plans.

Can I get a free trial?

Yes, you can sign up for free and preview this test.

I just moved to a paid plan. How can I request a custom assessment?
