9 reasons why

Adaface Ruby Online Test is the most accurate way to shortlist Backend Developers

Reason #1

Tests for on-the-job skills

The Ruby 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.

The Adaface Ruby test screens candidates for the typical skills recruiters look for Ruby developer roles:

Knowledge of the syntax of Ruby and its nuances
Strong understanding of object-oriented programming
Understanding of functional programming style in Ruby
Skills for writing reusable Ruby libraries that may be used in expressive ways
Familiarity with concepts of MVC, Mocking, ORM, and RESTful
Experience with popular web application frameworks such as Rails, Lotus, etc depending on project requirements
Familiarity with command-suite libraries, such as such as Thor and GLI, depending on project requirements
Knack for writing clean, readable Ruby code
Experience with both external and embedded databases
Understanding of fundamental design principles behind a scalable application
Able to create database schemas that represent and support business processes
Implementation of automated testing platforms and unit tests
Proficient understanding of code versioning tools e.g. Git, Mercurial or SVN
Familiarity with development aiding tools such as Bower, Bundler, Rake, etc
Familiarity with continuous integration

The insights generated from this assessment can be used by recruiters and hiring managers to identify the best candidates for the Ruby developer roles. Anti-cheating features enable you to be comfortable with conducting assessments online. The Ruby developer test is ideal for helping recruiters identify which candidates have the skills to do well on the job.

Reason #2

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.

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.

These are just a small sample from our library of 10,000+ questions. The actual questions on this Ruby Online Test will be non-googleable.

Reason #4

1200+ customers in 75 countries

With Adaface, we were able to optimise our initial screening process by upwards of 75%, freeing up precious time for both hiring managers and our talent acquisition team alike!

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Ruby Online 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.

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the Ruby Online Test from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

Reason #7

Detailed scorecards & comparative results

Reason #8

High completion rate

Adaface tests are conversational, low-stress, and take just 25-40 mins to complete.

This is why Adaface has the highest test-completion rate (86%), which is more than 2x better than traditional assessments.

Reason #9

About Ruby Developer Roles

Ruby is an interpreted, high-level, general-purpose programming language which supports multiple programming paradigms. It was designed with an emphasis on programming productivity and simplicity. In ruby, everything is an object, including primitive data types.

Proficient Ruby developers can use Ruby to build anything from the back-side of a web application to command line utilities on a computer. The language is dynamic, reflective, and object oriented.

Typical Ruby Developer responsibilities include:

Designing, building, and maintaining efficient, reusable, and reliable Ruby code
Ensuring the best possible performance, quality, and responsiveness of the applications
Identifying bottlenecks and bugs, and devise solutions to these problems
Helping maintain code quality, organization, and automatization

What roles can I use the Ruby Online Test for?

Backend Developer

The hiring managers felt that through the technical questions that they asked during the panel interviews, they were able to tell which candidates had better scores, and differentiated with those who did not score as well. They are highly satisfied with the quality of candidates shortlisted with the Adaface screening.

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.

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
Web proctoring
Webcam proctoring
Plagiarism detection
Secure browser

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.
