How to hire a Ruby Developer? Skills to look for, interview questions, and more.

Ruby is often used to design programs and software applications and also offers one of the best web app frameworks available in the market. Thus, it's a lucrative platform that offers agile web development and ensures an early entry into the market.

As one of the trending technologies among businesses and top enterprises, it is not easy to hire Ruby developers due to market demand. With the current competitive market and limited talent pool, hiring Ruby developers gets quite time-consuming and costly.

However, Turing's AI-powered talent cloud can help make things easier. Our deep-vetting talent platform leverages global reach to source high-quality developers and save 50+ hours of engineering time during recruitment. We select developers only after evaluating their technical skills in front-end development, object-oriented programming (OOP), database management, web development, and other core areas. Our rigorous vetting also ensures that developers possess strong communication skills for effortless remote collaboration.

If you're a non-technical hiring manager and want to know more about the process of hiring a Ruby developer, we've put up an excellent resource for you.

What are the skills to look for while hiring a Ruby developer?

Hiring Ruby developers requires a lot of skill sets that fulfill building scalable web applications. If you’re tasked with hiring a Ruby developer, this next section will give you a good idea of who to hire.

1. Proficiency in Ruby on Rails

As a Ruby developer, one must be well-versed in the Ruby programming language, including its object-oriented principles, syntax, and libraries. However, it's also important that they have an in-depth understanding of the Ruby on Rails framework, which is written in Ruby. Expert Ruby developers have a strong command of this framework, best practices, and its conventions, including ActiveRecord for routing, view rendering, and database management.

2. Excellent web development skills

When hiring Ruby developers, you must assess their front-end and web development skills. Expert Ruby developers use their experience to design your application or website in a way that relates to the users, by keeping all UI/UX elements in mind. Using JavaScript, the Ruby developer can also search any DOM, wrap the element in any hidden HTML, tackle the confirmation dialogues, and even more. Hence, when you hire Ruby developers, check if they are proficient in HTML, JavaScript, and CSS, and can work with APIs, integrate front-end elements into Ruby-based apps, and build responsive web interfaces.

3. Good database experience

Almost all Ruby on Rails applications relate to the database and come with a built-in SQLite. So, when you hire a Ruby developer, check if they have database proficiency. Basic familiarity with SQL is an absolute necessity. Even though the Ruby developer may not need to compose any SQL as ActiveRecord takes care of that, they may need to read logs to understand issues and resolve them. Expert Ruby developers are also experienced in working with relational databases like PostgreSQL or MySQL, and are adept at database migrations, data modeling, and querying.

4. Solid testing and validation skills

Before any real-time release, it is always a best practice to verify and test the end product. Although you can hire a separate team for quality assurance services, it is critical to have an expert who knows the pattern of running dummy commands and recognizing loopholes at the initial stage. When hiring a Ruby developer, check if they are skilled in writing automated tests and have expertise in testing frameworks like Minitest or RSpec.

5. Expertise with technical tools

A skilled Ruby developer needs to be grounded in code, technical tools, managing team members, project deployment, and a lot more. Therefore, when hiring a Ruby developer, check if they can use code management tools like Git and are also knowledgeable about functionalities such as making a new branch, pulling and pushing code, etc. Moreover, a Ruby developer with knowledge of different stages and platforms for deployment like Docker, Cl, Heroku, and others would be an additional advantage.

6. Experience in object-oriented programming

OOP or object-oriented programming is an important part of Ruby development as it enables the developer to get a virtual view of the codes. OOP is also essential to check the compatibility of codes and how they will work in real-time. So, when you hire Ruby developers, make sure they are familiar with OOP basics and principles, including inheritance, encapsulation, and polymorphism, and know how to use classes and objects to structure code.

Top interview questions to hire Ruby developers.

Recruiters associated with the tech industry are aware of the importance of sourcing exceptional talent. To get an overview of the candidate’s practical skills and gauge the level of proficiency, here are lists of possible Ruby questions to ask while conducting an interview.

You can start off the interview with a fundamental question to ensure the candidate knows what the language is all about. They must go beyond a generic definition to give a detailed explanation of the nitty-gritty of the language.

Some of the key advantages of the language include:

  • Pure Object-Oriented language: Everything in Ruby is an object—even methods, classes, and booleans. This greatly simplifies things from the coder’s perspective and opens up a range of possibilities.
  • Open-Source: Ruby is 100% free and open-source, with a large and enthusiastic community that can be tapped into as a resource.
  • Metaprogramming: Ruby is widely considered to be one of the best programming languages out there for metaprogramming, or the ability to write code that can act on other code instead of data.
  • Clean and simple syntax: The syntax is simple and concise, which allows developers to solve complex programs with fewer lines of code. It is also worth noting that the code is readable and easy to follow.

Garbage collection performs various functions including allowing for pointer values removal and removing the inaccessible objects from the memory, among other things. In essence, garbage collection helps free up memory space for other processes.

Methods may either be public, protected, or private in Ruby. Public methods can be called by anyone, protected methods are only accessible within their defining class and its subclasses, while private methods can only be accessed and viewed within their defining class.

Though Ruby on Rails has various advantages, asking about the limitations can help you ascertain if the developer is oblivious of the setbacks or aware of what’s obtainable with the language. An experienced developer will explain by highlighting the various features it doesn't support making it unusable for some programmers. This includes linking to more than one database at a time, connecting to multiple database servers, and utilizing foreign keys in the databases.
