Premium questions with real-world problems

The HTML/CSS, React, Node.js, and MongoDB online test assesses the candidate's ability to develop applications using both front-end skills (React and HTML/CSS) and back-end skills (Node.js and MongoDB).

It's an ideal test for pre-employment screening. A good full-stack Node.js developer, who is using React for the front-end, and MongoDB as database engine, 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 MongoDB 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 answer multiple-choice questions about MongoDB.

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.
