So if you’re looking to hire a skilled Ruby developer for your company, we have crafted a comprehensive guide covering various aspects ranging from selecting to hiring the right Ruby developer.

Essential things to look for while hiring Ruby developers

While putting out a vacancy, every company has specific requirements for different profiles, i.e., Junior Ruby developer, intermediate Ruby developer, or senior Ruby developer with years of experience varying from profile to profile. Along with the technical understanding, a dedicated Ruby developer must also possess non-technical skills. Therefore, before thinking about hiring a Ruby developer, you should figure out the qualities that an ideal candidate must have.

To make it less complicated for you, here’s the list of a few common skills that are required by all, from a novice developer to an expert Ruby developer:

1. Expert knowledge of Ruby programming

Ruby, a highly portable general-purpose language, is well suited to building desktop applications, static websites, data processing services, and even automation tools. With the knowledge of the Ruby programming language and the added functionality of the Rails application framework, Ruby developers can do a lot.

2. Hands-on experience with Ruby on Rails (ROR)

Popular for long-term projects needing significant transformations with heavy traffic or MVPs, Ruby on Rails is a server-side web application development framework written in Ruby programming language. A Ruby developer should have hands-on experience with the Ruby on Rails framework.

3. Automated testing

Ruby is well known for certain specialized functions like runtime methods, which speed up the automation process. Developers who are well versed in writing these test automation scripts can ace the game. Therefore, before hiring Ruby developers, ensure they know about Automated testing and its various facets. This will help them validate if the software is working as expected.

4. Experience with APIs

APIs are Application Programming Interfaces that allow communication between two applications. They are required to easily share data and execute pre-defined processes.

Ruby developers should be well aware of APIs to discern how the communication occurs between two applications. They should have a basic understanding of public classes, methods, and properties that define this interaction.

5. Database

To write fast, secure, and reliable applications, Ruby developers should be well versed in using database technologies such as Oracle, PostgreSQL, MySQL, etc. It will help them organize information, detect errors, and debug applications to improve the overall application performance.

6. Domain knowledge and skills

A dedicated Ruby developer should have the basic knowledge and skills such as database management, expertise in integrating data from different sources, and knowledge of APIs. In addition, an expert Ruby developer must have handled various Ruby projects in the past and know how to navigate through obstacles to build robust applications.

7. Effective communication

There are times when a developer has to explain technical concepts to various stakeholders and other team members for successful collaboration. Hence, an expert Ruby developer must have decent communication skills for seamless technical and non-technical communication.

8. Work portfolio

The portfolio is the best way through which developers can show off their skills. It also demonstrates developers’ ability to work within a team or individually. A quick scan through the portfolio is a great idea to know someone’s achievements and the kind of work they’ve been doing. A recruiter must pay close attention while going through developer portfolios.

9. Up-to-date with the latest trends

Expert Ruby developers must keep themselves up-to-date with the latest technological developments. It helps them identify opportunities for improvement in the existing products and systems and implement new solutions to overcome the challenges.

Best ways to hire a Ruby developer

To get the best talent for your company, you can use either of the three ways as per your requirement.

1. Outsourcing

If you have time, budget, or resource constraints, deep jobs platforms like Turing can help you hire reliable and talented Ruby developers. You can save ample time and money throughout the hiring process as the outsourcing platform will take care of everything from sourcing to vetting to managing the developers.

2. Freelance Ruby developer

Hiring a freelance developer is the perfect option when you want to hire a developer for a small gig. Many platforms provide great freelance Ruby developers to work on specific projects. However, this method of hiring has its pros and cons.

Hiring a freelancer may work for some as it is the most cost-effective, but you may have to make constant follow-ups with the freelance developer to get updates on the project. Also, it requires paying attention to their experience and skills as they are equally important when it comes to freelancing. Sometimes, it can also be risky as there are chances that you might end up hiring the wrong candidate.

3. Full-time employment

Websites like LinkedIn, Indeed, Monster, etc., can help you get started searching for full-time developers. As it is a long-term opportunity, you must carefully access the applicants and pick your developer. Post a job with proper description and requirements as it will help you attract the right talent for your company.

What’s the best way to assess a Ruby developer?

Once you have thoroughly screened the resume and assessed a developer’s abilities and achievements, you can schedule an interview. To know the candidate better, you can evaluate their skills and knowledge in 3 ways:

1. By checking theoretical knowledge

Check out the top interview questions for Ruby developers, which can help you evaluate their technical proficiency. There’s no end to the theoretical questions you can ask the Ruby developer. Do not forget to include the ones that will demonstrate the knowledge you need for the project.

2. By a coding assignment

A coding test will help you assess a developer’s proficiency with programming and technical knowledge. The coding assignment should be similar to the project you want them to work on. While assigning them the technical task, give them a timeline for the deliverables to avoid confusion.

3. By asking general questions

There are some common questions that you can ask any developer. E.g., Why did you choose Ruby as your programming language? Why do you want to work for us? Although these are common questions, their response will tell you a lot about the developer's personality as to whether they’re genuinely interested in the profile or just want a job change.

Five common mistakes to avoid while hiring a Ruby developer

Many top companies compete to hire the right talent to be a good fit for their organization. Imagine how challenging it is to find the talent that will benefit your company from a limited pool of skilled developers. Lack of technical knowledge or improperly analyzing the applications can make you hire the wrong candidate. We have listed a few mistakes to avoid while hiring Ruby developers:

1. Not screening the application properly.

Screening the applications is vital to filtering quality candidates and eliminating unqualified applicants. Any mistake at this step can cost you time, money, and resources. Therefore, make sure to do an introductory call with the candidate. At this stage, you can cross-check the information they have provided on their resume by asking relevant questions.

2. Hiring inexperienced developers

It may appear affordable to hire an inexperienced developer to save money. But is it worth it? Sometimes cost-cutting isn’t the ideal solution for you. There are chances that the Ruby developer you’re looking for may need specific expertise and experience.

Remember, the more experience the developer has, the finer the product will be. Plus, an experienced Ruby developer knows how to overcome challenges and will be able to understand your requirements better.

3. Testing wrong skills

While hiring, many employers ask and judge Ruby developers for irrelevant skills or knowledge not related to the project. That is a waste of time for both- developers and companies. It is better to test the skills you are looking for in your developer.

When looking for a Ruby developer, you must prepare a list of questions related to the project and skills beforehand.

4. Selecting based on resume alone

A resume is a crucial part of the selection process but shouldn’t be the only thing. Developers tend to exaggerate their achievements in their resumes. In addition to the resume, you must carefully assess the skills and experience of the Ruby developer.

5. Not cross-checking the references.

After going through the complete process, you can always get a second opinion from their previous employer about their potential and caliber when you've finalized the right developer for the team.
