How to hire a RoR developer? Skills to look for, interview questions, and more

Ruby on Rails has emerged as a breakthrough technology in recent years and many top companies like Airbnb, GitHub, Shopify, and SlideShare use it to build robust, reliable, and scalable applications. The framework requires less code and is easy to use, which makes it a popular choice among developers and businesses to build powerful web applications faster.

Because of these reasons Ruby on Rails developers are high on demand and hiring expert Ruby on Rails developers has become a cumbersome task. So, how to hire Ruby on Rails developers quickly? Turing offers a hassle-free way to hire experienced and deeply-vetted Ruby on Rails developers.

We rigorously vet developers and simplify the hiring process for you. You can find highly talented Ruby on Rails developers for hire and onboard them in just 4 days.

Furthermore, if you're a non-technical manager looking to know more about the hiring process for a Ruby on Rails developer, we've compiled an excellent resource for you.

Let’s get started!

Skills to look for in a RoR developer

Hiring a skilled Ruby on Rails developer can be challenging, given the vast pool of developers available these days. When you look for an adept Ruby on Rails developer, you must consider several essential skills to ensure that the candidate is the right fit for your project. The following are the crucial skills to look for before you hire Ruby on Rails programmers.

1. Highly Proficient in Ruby

Ruby language is the foundation for the Ruby on Rails framework. An ideal Ruby on Rails developer must understand basic to advanced concepts of Ruby. They must have a strong understanding of Ruby's syntax, data types, and objects to leverage the features of the framework.

Ruby on Rails relies heavily on Ruby's syntax, routing mechanisms, and template engines. Programmers with in-depth knowledge of Ruby can create better templates, design complex routing systems, and unlock the full potential of Ruby on Rails MVC architecture. Therefore, when you hire Ruby on Rails developers, ensure that they are proficient in Ruby.

2. Well-versed in the Ruby on Rails framework

Ruby on Rail developers must have extensive knowledge of the framework because they will use it to write code regularly. They must be proficient in Ruby libraries and gems. These are readymade tools that enable developers to add various functionalities to the application without writing new code from scratch. The framework also provides a collection of generators and tools that simplify and accelerate the application development process.

Besides that, knowledge of ActiveRecord is essential for a Ruby on Rails developer because it is a fundamental component of the Rails framework. ActiveRecord is an Object-Relational Mapping (ORM) system that enables developers to work with a database using object-oriented programming techniques.

3. Familiar with front-end development

Familiarity with front-end development is essential for a Ruby on Rails developer because applications built using Ruby on Rails require front-end development to create responsive, visually appealing, and user-friendly interfaces. Hence before you hire Ruby on Rails developers, check their proficiency in frontend development.

Knowledge of front-end technologies like HTML, CSS, and JavaScript enables Ruby on Rails developers to integrate their back-end code with the front-end codebase seamlessly.

The developer will be able to search any DOM, wrap the element in any hidden HTML, manage confirmation dialogues, and much more using JavaScript. Moreover, expertise in front-end development technologies enables Ruby on Rails developers to efficiently troubleshoot issues and debug code, bringing more value to the development process. So, make sure to evaluate the candidates’ proficiency in frontend development when you hire Ruby on Rails developers.

4. Knowledge of database management

As Ruby on Rails is primarily a back-end web development framework that interacts with databases, a Ruby on Rails developer must have a solid understanding of SQL database design and management concepts. MySQL is often used in conjunction with Ruby on Rails as an open-source database management system, and knowledge of this database is essential for application development and management.

Knowledge of SQL enables developers to write queries to manipulate data and optimize database performance. Furthermore, proficiency in database management helps developers optimize database performance, enhance scalability, and ensure data integrity while providing a secure environment for data storage and access.

5. Understanding of version control and deployment tools

Expertise in version control tools enables developers to track the changes in the codebase and roll back to previous versions in case of a critical error. When looking to hire Ruby on Rails developers, make sure they know how to use the version control tools like Git and Mercurial.

Git is a must-have tool for code management because it is the de-facto standard for version control. The RoR developer should be able to build new Git branches and push code into them.

On the other hand, Docker is an open-source platform designed to simplify the development, deployment, and running of applications in a containerized environment.

6. Testing and validation skills

Testing and validation ensure that the code meets the expected functionality and quality standards. It can uncover bugs, issues, and vulnerabilities in the codebase early on so that they can be fixed before they harm the system or user experience.

With proper testing and validation, developers can continuously integrate and deliver the code which is crucial in agile and efficient software development. This helps in faster delivery, faster feedback loops, and smoother development and deployment. So, check the candidate's automated and manual testing and validation skills before you hire Ruby on Rails experts.

7. Soft skills

Soft skills are as important for a Ruby on Rails developer as technical skills because they play a significant role in the success of software development projects. The ability to explain ideas and communicate with team members and other stakeholders throughout the development process is essential in ensuring that everyone is on the same page.

Besides that, soft skills such as creativity, critical thinking, leadership skills, and problem-solving abilities are essential to enhancing the end product's quality and completing projects on time. Hence, hire Ruby on Rails developers who display excellent soft skills for a smooth and streamlined development process.

Top interview questions to hire Ruby on Rails developers

Whether you're an IT recruiter or an engineering leader, you must be aware that finding top developers is critical to the success of your project. An interview plays a critical role in the hiring process and helps you evaluate the right candidate. Here are some sample interview questions you can use when you want to hire Ruby on Rails developers.

A senior role applicant, or one who claims to have worked with Rails for more than two years, must be familiar with at least a few of the new features in Rails 5. Even though the feature list is short, the candidate should be able to emphasize important features.

Every RoR developer should be aware of Ruby on Rails' basic ethos, "Fat Model, Skinny Controller." On the other hand, senior developers should say they favor Skinny Models, Skinny Controllers, and Fat Services.

This is another important question to evaluate a candidate’s knowledge when you have to hire expert Ruby on Rails developers.

RSpec and Minitest are both testing frameworks used in Ruby on Rails, but the main difference lies in their philosophy and syntax. RSpec uses BDD (behavior-driven development), focusing on human-readable behavior specification and acceptance tests, which makes it more suited to a collaborative and client-driven development environment. RSpec has a slightly more detailed and expressive syntax than Minitest, and it requires more boilerplate code to set up.

On the other hand, Minitest uses TDD (test-driven development) and offers a simpler and more concise API with a less specialized syntax. It allows for easy integration of additional testing frameworks with minimum configuration, making it more suited for small-to-medium-sized projects.

An expert Ruby on Rails developer should be able to explain that a Hash is a type of Ruby class. It’s a group of key/value pairs that makes it simpler for developers to access values by keys. The keys and values can be any data type supported by Ruby. Hashes are commonly used to store and retrieve values using keys instead of array indices. Hashes are created using curly braces {} or the hash keyword.

Garbage collection is a mechanism in Ruby on Rails, just like other modern languages, that automatically manages the dynamic allocation and deallocation of memory. It removes pointer programs and inaccessible objects left behind after the execution of a program to free up memory which allows the developers to create and destroy objects dynamically without worrying about memory space management.

In Ruby on Rails, a closure is a function or block of code that can be passed as a parameter to or returned from another function. In simpler terms, a closure is an object that binds together a function's code and its environment so that the function can access variables that are not part of its parameter list. Closures, also known as blocks or lambdas, are useful in Ruby on Rails for creating callback functions and creating private namespaces.
