Ruby and SQL online test

The Ruby and SQL test assesses candidates' knowledge of programming in the Ruby language as well as the ability to use SQL for data access.

It's ideal for pre-employment screening of Ruby back-end developers, as they need to be able not only to solve problems using Ruby but also to write and analyze SQL queries used for communication with the database.

This test requires candidates to be able to solve coding problems in Ruby and answer questions about SQL queries and relational database concepts.
