This Is How You Interview a Ruby Developer

Ruby is a dynamic, open source programming language that sets its prime focus on productivity and simplicity. Software development agencies choose Ruby because of its elegant syntax that is easy to write and read. If you want your software to be written in this language, it’s high time to search for qualified Ruby developers. In this article, we are going to outline some key technical skills that will help you spot an ideal candidate for the position of a Ruby developer.

What a Ruby Programmer Has to Know

  • Ruby programmers should demonstrate good skills in Ruby syntax and its nuances.
  • An experienced Ruby developer should be able to provide a clean, efficient, and high-quality Ruby code along with reusable Ruby libraries.
  • Good understanding of both goal-oriented and functional programming is also important for Ruby developers because of Ruby’s support of these paradigms.
  • A Ruby developer should have experience with JavaScript/jQuery.
  • A Ruby programmer should have an understanding of the MVC concepts and patterns.
  • Experience with consuming web services, such as XML or JSON, and building RESTful web services also belongs to the skillset of a professional Ruby programmer.
  • A Ruby developer should have experience with popular web application frameworks, such as Rails, Lotus, Sinatra, Grape, etc., depending on project requirements.
  • A professional Ruby programmer should possess an experience with cloud computing and cloud services, such as AWS.
  • An experienced Ruby developer should understand Unix commands and be able to execute them in a Linux/Unix terminal/command line.
  • Experience with both external and embedded databases, such as ActiveRecord, MySQL, PostgreSQL, etc., also belongs to qualifications of a Ruby programmer.
  • A Ruby developer should understand the essential design principles behind a scalable application.
  • A Ruby programmer should understand how typical Rails deployment works with Capistrano or Mina.
  • Experience with background job runners, such as Sidekiq, is also important for Ruby programmers.
  • A Ruby developer should be able to create database schemas that represent and support business processes.
  • A Ruby programmer should be familiar with DevOps tools, such as Jenkins.

If your Ruby developer candidate is able to demonstrate most of these skills not only in their CV but also during the technical interview, then you are lucky. We wish you a fruitful cooperation with your new employees!
