Ruby, a flexible programming language focused on efficiency and simplicity, is widely used to create web applications, e-commerce stores, and mobile applications. Ruby, which is also used by companies such as GitHub and Zendesk to code and design websites, is one of the most popular software languages. So, which questions do you think are most frequently asked in job interviews in this field?

Developments in the e-commerce sector have made Ruby the best programming language for all kinds of online stores, blogs, and platforms. Many websites are built in this framework and the demand for IT professionals proficient in this language is increasing. Ruby developers are increasingly sought after for their versatile development skills. The ability to implement both back-end and front-end development projects means that Ruby On Rails developers can describe themselves as full-stack programmers.

So, which questions can you face during the interview according to your seniority level? Here are some examples!

Basic level Ruby interview questions:

  • How many types of variables are used in Ruby and what are they?
  • What are the levels of access control for Ruby methods?
