Those are just some big names, but there are literally hundreds of thousands of applications built with the framework since its release in 2004. Ruby on Rails is open source software, so not only is it free to use, you can also help make it better.

More Mobile We are ROR experts, but building great products would not be possible without knowledge and extensive usage of many other things, e.g. HAProxy, Nginx, React/Angular, PostgreSQL, Redis, Redshift, AWS, Heroku and many-many more. Our experts write truly modular, reusable code and effectively collaborate with the team.
Our unified APIs and “mobile first” approach in application design is our “secret sauce” for the apps’ flawless look and feel on both Android and iOS. The entry point of the backend is the load balancer, which is proving requests to a combination of Nginx and Passenger.
For standard web applications we use ROR as a core technology, but for high loaded real-time systems Erlang is just a better option. We also have extensive experience with both types of hosting, the classical hardware and modern cloud based.
In each particular case developers design a specific technological stack to sustain needs of the application, as well as to make it stable and fast. Our Ruby On Rails developers have implemented a bunch of different integrations, e.g. social networks(Facebook, Twitter), payment systems (PayPal, Stripe, Braintree), geography services (Foursquare, Google Maps/Places, Yahoo Local, Yelp, etc.
), email marketing (Send grid, Mailchimp), business tools (LinkedIn, Zendesk, Pivotal Tracker), etc. We at RubyGarage want to share our knowledge about how to interview a Ruby on Rails developer.
You can consider this article as a guide for how to interview a Ruby on Rails programmer. For example, we decided to omit questions about code idioms and cunning expressions in Ruby.
We merely want to see how a Ruby software engineer expounds their knowledge of the domain. The article will be divided into several parts since we usually check separate domains of knowledge.
We want to hire forward-thinking software engineers who will create high-quality code, and so we want to assess their Ruby competence. Class hierarchies, encapsulation, inheritance, and polymorphism are key concepts that every Ruby on Rails web developer should know well.
If a programmer correctly answers a list of questions similar to the ones below, then we move forward. Quality preparation for a job interview is important for a Ruby programmer.
What are the three levels of method access control for classes and what do they signify? Knowing the basics isn't enough to work for RubyGarage or for any other serious web development company.
A programmer should also be able to explain how to write code for business applications. Since Rack is a very popular interface that makes it possible to develop an application in Ruby, we ask specific questions about it.
Ruby is a very popular programming language, and it has a huge community of developers who create numerous helpful libraries. We at RubyGarage love gems because they simplify and accelerate the work process.
Third-party code helps us develop web applications quickly and smoothly. The interviewee should also describe Rutgers, which is a special system to create, implement, and share gems.
Can you give me some examples of your favorite gems besides Ruby on Rails ? A qualified developer should be familiar with the Model-View-Controller approach to building applications.
And finally, the ActiveRecord-related questions let us test how the programmer understands the Model part of an application. In order to work efficiently, a developer should write as little configuration code as possible when making ActiveRecord models.
Top Ruby on Rails Interview Questions What is Active Job? Explain the difference between Page, Action, Fragment, Low-Level, SQL caching types.
We only hire programmers with a deep understanding of what types of attacks can be unleashed against a Ruby on Rails app. Besides possible attacks, a developer should also know everything about existing methods of protection.
Automated testing in Ruby on Rails helps reduce the workload for the Quality Assurance team, and this will greatly improve the workflow. Refactoring means that developers brush up the code they have already written to make it cleaner and more efficient.
We want our Rails programmers to write high-quality code that is maintainable and expandable. If a developer knows how to reach high-level performance, then the team will be able to improve the application faster in the future according to the client's changing requests.
What are your favorite tools to find code smells and potential bugs? Explain extract Value, Service, Form, View, Query, and Policy Objects techniques.
The next part of our Ruby on Rails interview always involves testing a programmer’s skills while paired with our senior web developer. It doesn’t matter whether the interview is held online via Hangouts or Skype or whether it’s in-person, as we simply ask the interviewee to share their screen and start solving a task.
Once a Ruby on Rails programmer gets the task, they should suggest some methods or means to resolve it. A pair programming task is very similar to a discussion, as our senior web developer helps the interviewee understand what solution might be not only workable, but best.
Secondly, the pair programming tasks helps us determine a developer’s ability to work in a team. Write a function def binary_gap(n) that, given a positive integer N, returns the length of its longest binary gap.
We further include tasks to test a developer’s ability to write autotests using tools such as Spec, Capybara, and similar. For example, we may ask a Rails developer to implement a task with React, Ember, or Backbone instead of Angular.
The particular task we give may depend on a particular project on which the Rails developer will work if hired. Once a developer resolves our home task, and we check the result, we can know for sure if this programmer is ready to work with us or not.
This programming task, to be completed solely by a job seeker, is very valuable to verify his or her skills. It should have client side and server side validation; It should work like a single-page WEB application and should use AJAX technology (load and submit data without reloading a page); It should have a user authentication solution.
