Benefits of using Ruby for your project

Without a doubt, Ruby is one of the most popular and reliable programming languages in the tech community. It even has its own Ruby on Rails framework. The language comes with a wide range of features that allows developers to build high-quality web applications efficiently.

Open source and flexible

Ruby comes with an open-source library that allows developers to share their codes with other community members. Such networking makes it easier for beginners to learn the ins and outs of the language.

Additionally, it offers high flexibility, enabling Ruby developers to add multiple objects and methods to the solution without disrupting stability. As a result, it simplifies the creation of flexible APIs.

Consistent in nature

One of the prominent features of Ruby is that it is generally consistent in nature which is extremely beneficial for a developer, especially if they have just started out with the language. Consistent syntax enables developers to build the solutions without learning a lot of new things. So, any application can be created without going through a significant learning curve, consequently making the entire development process less time-consuming and improving productivity and performance.

Extremely secure

Ruby is a trusted programming language that puts a strong emphasis on securing solutions. It makes the job of a Ruby developer easy by preventing any data from being hijacked or overwritten. When utilizing Ruby development services or features, programmers can secure all sensitive data records and ensure that such data is not accessible to any external threat.

Improved processing

Development teams can now easily configure and develop solutions on Ruby with the help of its multi-threading or native thread support. This allows developers to execute multiple programs at once without slowing down the system. Furthermore, the language is portable, meaning that programs written on it can be operated across multiple operating systems.

Easy management

Ruby is a simple programming language that is extremely easy to understand than any other programming language. In fact, it significantly simplifies the extensive changes that most projects require at any stage of the software development process. Besides, as a company grows or evolves, so does the software solution you create or utilize. Since Ruby offers a simplified change and management process for the codebase, it becomes much easier for businesses to scale their operations in the future if needed.

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

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

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 developer. Do not forget to include the ones that will demonstrate the knowledge you need for the project.

By a coding assignment

A coding test will help you assess a developer’s programming proficiency 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.

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? Do you have any experience with project management? 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.

By reviewing the resume

The candidate’s resume is a window to their level of skill and aptitude. This gives you an overall impression of the candidate's previous work experience and if it matches your requirement.

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 that can be avoided when you hire Ruby developers:

Not screening the application properly.

Screening the applications is vital to filter quality candidates and eliminate 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.

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.

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.

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.

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.
