Ruby on Rails is becoming a widely used technology in web development - and like other IT professionals, Ruby developers are increasingly often hired offshore. That is a great opportunity for a business to cut down expenses, but the hiring becomes more challenging.
Finding the right developers in a pile of CVs is always difficult, and when you hire an offshore Ruby on Rails developer, you get additional challenges, like the language and cultural barriers, the specifics of their education system and the way development process is organized in their country, and so on. That’s why the right Ruby on Rails interview questions matter even more for offshore staffing than they do for an onshore hiring campaign.
The main goal of your offshore Ruby on Rails developer interview should be to identify the programmer who has both theoretical knowledge of the language and the framework and a deep understanding of and practical experience with them.
Start the interview with a sort of Ruby on Rails test to check your candidate’s level of knowledge. These Ruby on Rails interview questions can be grouped like this:

After that, you can proceed to more in-depth questions that will help you see if the candidate has a bigger picture of the technology and how thoughtfully they apply it in development.
These are the questions that create a discussion and encourage your potential Ruby developer to express their opinion. Good examples are:
These lists of questions are far from complete, but, hopefully, they will be helpful in your process of finding the right offshore Ruby on Rails developer.
