Ruby on Rails is a popular, open-source, client-side web application framework. The framework offers an expansive list of code libraries to build websites and web applications. It also provides robust default data structures for configuring databases, web services, and web pages. Ruby on Rails is a Model-View-Controller (MVC) framework that supports software development paradigms such as Convention over Configuration (CoC), don’t repeat yourself (DRY), etc. 

Ruby on Rails was developed in 2004, using a programming language from 1995. The framework also allows active record patterns to store data across relational databases. RoR also allows faster web development through seamless data migrations, speedy table creations for databases, and ‘View Scaffolding’ options.

The framework’s popularity has created a large community of Ruby on Rails developers across the globe. More than a hundred thousand companies across the US use Ruby on Rails for their website development.

What are the requirements and responsibilities of Ruby on Rails Developers?

Hiring managers seek expert Ruby on Rails developers to work on back-end web development projects. Senior Ruby on Rails developers possess a versatile web development skillset, with expertise in performing front-end and back-end tasks. Junior Ruby on Rails developers understand the rudimentary concepts of Ruby, MVC, client-side database development, etc. Here are some of the main differences between junior and senior Ruby on Rails developers:

Junior Ruby on Rails Developers

Junior Ruby on Rails developers have a basic understanding of web development languages, platforms, and SDLCs. Most junior RoR developers are proficient in HTML, CSS, JavaScript, Bootstrap, and other web development technologies.

Junior Ruby on Rails developers know the syntax, features, and semantics of the Ruby programming language. To code with the Ruby on Rails framework, developers use different elements of Ruby such as loops, modules, gems, conditional statements, classes, etc. Junior Ruby on Rails developers need to know multiple aspects of Object-Oriented Programming (OOP).

In addition, junior Ruby on Rails developers must also possess good soft skills to collaborate with team members seamlessly. And so, hiring managers prefer recruiting junior RoR developers who possess an adequate blend of tech skills and soft skills.

Senior Ruby on Rails Developers

Most senior Ruby on Rails developers have 5+ years of experience. Senior RoR developers know how to use code management tools (Git), deployment tools (Heroku), and productivity tools.

Senior Ruby on Rails developers can structure the application and website using the Model-View-Controller (MVC). In addition, senior RoR developers can use ERB (Embedded Ruby) and HAML (HTML Abstraction Markup Language) for viewing systems. They can use ActiveRecord commands for data modeling, data migration, data association, and data validation. 

In addition, senior Ruby on Rails developers have hands-on experience with RSpec, a modular testing tool. And senior RoR developers can use  JSON format within Application Programming Interfaces (APIs). 

Expertise in REST apps, HTTP statuses, and other web development tools is a prerequisite for senior Ruby on Rails developers. Moreover, most senior RoR developers have excellent soft skills, and are great team leaders. 

Where can you hire Ruby on Rails developers?

Hiring managers can explore multiple options for hiring Ruby on Rails developers. 

Some of the primary methods to hire RoR developers are as follows: 

Job posting websites

Hiring managers can post the requirements for Ruby on Rails developers on job portals like Monster, Indeed, etc. But common job posting websites do not offer sophisticated vetting methods to gauge a candidate’s experience, soft skills, and expertise. In addition, job posting websites have many limitations, such as a long and slow hiring pipeline, a lack of automatic screening methods, and a lack of consistency. 

Professional social networking platforms

Professional social media websites LinkedIn, Meetup, AngelList, etc., are alternative platforms to hire Ruby on Rails developers. But these platforms are often inefficient due to a high level of fluff, false endorsements and recommendations, and a lack of adequate assessment methods.

Interview questions to hire Ruby on Rails developers

Junior-level interview questions

  1. What are the advantages of Ruby on Rails?

    Some of the main advantages of Ruby on Rails are scalability, consistency, efficiency, security, and cross-platform support. RoR offers a bug-free web development platform with excellent testing capabilities.
    Asking this question would help you understand why a candidate prefers Ruby on Rails over other web development frameworks.
  2. What are the disadvantages of Ruby on Rails?

    The disadvantages of Ruby On Rails are rigidity, performance bottlenecks, and constraints. Due to the framework’s rigidity, any issues with data architecture that are detected late in the web development life cycle can lead to heavy costs of coding. Knowing these disadvantages would allow web developers to plan the feasibility of using Ruby on Rails early on.
  3. Mention a few features of Ruby.

    Some of the features of the Ruby programming language are as follows:
    1. Dynamic and duck typing
    2. Short and flexible syntax
    3. Object-oriented programming
    4. Metaprogramming
    5. Garbage collection
  4. What is the application of the garbage collection feature in Ruby on Rails?

    The garbage collection feature of Ruby on Rails ensures that the programmer does not need to manually relocate dereferenced memory. Garbage collection in RoR performs automatic memory management of data objects. Garbage collection eliminates coding errors such as wild pointers, double-free bugs, and memory leaks.

Senior-level Ruby on Rails interview questions

  1. How does Ruby on Rails trigger AJAX Operation?

    AJAX allows web pages to refresh automatically when the server reflects changes. Ruby on Rails can trigger AJAX operation when:
    1. A change on the server level is initiated when trigger fires are launched with a button/link click.
    2. The web client calls upon the server while executing an XMLHttpRequest.
    3. The server sends an HTML fragment when triggered by a server-side action handler.
    4. Ruby on Rails generates client-side JavaScript, which receives and updates an HTML fragment within the page.
  2. What are the uses of Ruby on Rails migration?

    Ruby on Rails migration can rename a table, add a column, change or edit a column, drop a table, remove a column, and perform other similar operations. Ruby on Rails migration is used to change and update database schema over time. Using Rails migration makes your application database-independent, making it easier to switch platforms if required.
  3. What is CSRF? How does Ruby on Rails work against CSRF?

    Cross-Site Request Forgery (CSRF) is a form of cyber attack used by hackers to damage or reveal confidential information. The protect_from_forgery command in Ruby on Rails Application Controller is helpful against CSRF attacks. This command generates CSRF tokens, verifying any post, put, or delete requests within your web application.
  4. What does the Rails controller do in Ruby on Rails?

    Ruby on Rails controller handles the interaction between the model, views, and users. As a logic center, the controller routes external requests and performs corresponding internal actions. The controller regulates helper modules to operate view templates without unnecessary lines of code. Rails controller also regulates live sessions to inform users about their interaction with the system.

Step 5: Onboarding RoR developers

To ensure a smooth onboarding process, hiring managers must follow certain protocols. Some of the major steps involved in onboarding new Ruby on Rails developers are as follows:

  1. Hand over the paperwork and complete the documentation process.
  2. Share the access to productivity tools, software, and the Integrated Development Environment (IDE).
  3. Send a welcome email, and possibly a welcome package consisting of company-branded goodies.
  4. Introduce the candidate to the team members and team leader.
  5. Assign a teammate as their point of contact to clear doubts about their tasks, and help them understand the company culture.
