Premium questions with real-world problems

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.

TestDome is trusted by businesses large and small

Pass/fail grouping

Our tests are designed to put candidates into either the pass group or the fail group so you can find the best candidates faster.

Full customization

We have pre-built tests and questions, but you can customize them however you like. Change the pass/fail scores, time requirements, and more.

Cheating protection

Use tests that solve real-world problems, with no answers that can be easily found online. Because we test performance and skills (not information), we allow the use of online resources, just like in real life. Copy/paste prevention and online proctoring via webcam prevent cheating.

Candidate reporting

Get an overview into the percentage of passes and fails. Then dive deeper into the results of your top candidates to select who goes onto the next phase of hiring.
