The HTML/CSS, React, Node.js, and SQL online test assesses candidates' knowledge across the whole Web stack from HTML, CSS, and React on the Web front-end and Node.js on the back-end to SQL for data access.

It's an ideal test for pre-employment screening. A good full-stack Node.js developer, who is using React for the front end, must be able to solve problems using Node.js and also to combine React and HTML/CSS to create dynamic and interactive user interfaces. Moreover, they must know how to write and analyze SQL queries, which are used to communicate with the database.

This online test requires candidates to solve common HTML/CSS challenges, React and Node.js coding problems, and to write SQL queries that extract, combine, and manipulate data.
