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 Online Test will be non-googleable.

What topics are covered in the Ruby Online Test?

Ruby Basics: Ruby Basics cover the fundamental concepts and syntax of the Ruby programming language. It includes topics such as variables, data types, operators, loops, and conditionals. This skill is measured in the test to assess the candidate's understanding of the core building blocks of Ruby.

Data Types: Data Types in Ruby determine the kind of values that variables can hold. It includes numeric types, strings, arrays, hashes, and booleans. Measuring this skill helps evaluate the candidate's capability to work with different data structures and manipulate data effectively.

Control Flow: Control Flow in Ruby involves the flow of program execution based on conditions and decisions. It includes concepts like if statements, case statements, and loops. Measuring this skill helps gauge the candidate's ability to control the logic and flow of their program accurately.

Methods: Methods in Ruby are reusable blocks of code that perform specific tasks. They enhance code organization, readability, and maintainability. Measuring this skill allows recruiters to assess the candidate's proficiency in creating and using methods to modularize their code and improve efficiency.

Classes and Objects: Classes and Objects form the foundation of object-oriented programming in Ruby. They allow for the creation of blueprints (classes) that define the behavior and attributes of objects. Measuring this skill helps identify candidates who can design and implement well-structured and reusable code using object-oriented principles.

Exceptions: Exceptions in Ruby allow for handling and managing errors and exceptional situations during program execution. They provide a way to gracefully handle unexpected scenarios. Measuring this skill helps evaluate a candidate's ability to write robust and resilient code by handling exceptions effectively.

Modules: Modules in Ruby are containers for groups of methods, constants, and classes. They provide a way to share functionality across different classes without using inheritance. Measuring this skill helps assess the candidate's understanding of code reuse, encapsulation, and separation of concerns using modules.

File Handling: File Handling in Ruby involves reading from and writing to files. It includes operations like opening, closing, reading, and writing data to files. Measuring this skill allows recruiters to evaluate a candidate's ability to work with file systems, manipulate file data, and perform file-related operations effectively.

Regular Expressions: Regular Expressions in Ruby are powerful patterns used for matching and manipulating text. They offer a concise and flexible way to perform string matching and replacement operations. Measuring this skill helps identify candidates who can leverage regular expressions to handle complex text-based tasks and validate input data efficiently.

Database Connectivity: Database Connectivity in Ruby involves integrating Ruby applications with databases to store, retrieve, and manipulate data. It includes concepts like connecting to databases, executing SQL queries, and handling data results. Measuring this skill helps assess a candidate's ability to work with databases, perform CRUD operations, and interact with data persistently.

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.

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?
