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

It's an ideal test for pre-employment screening. A good full stack PHP developer needs to be able to use a wide range of technologies.

This online test requires candidates to solve coding problems and find and fix bugs in multiple technologies.

What Others Say
TestDome user reviews on G2 Crowd
Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.

Jan Opperman, Grindrod Bank

Very smooth, well supported, great for assessing candidates

Very Prompt and helpful support when needed, we were looking to work with a third party to write and set up new tests, TestDome was able to quickly set up and support a method to do this, allowing us to start testing candidates straight away.

George Offer, Guided Solutions

Easy to use and efficient for testing developers of different levels

It provides us an opportunity to set our own timing policy, to choose from variety of questions from different areas and with difficulty gradation. Also it is great that TestDome provides free of charge tests for candidates to prepare and check how online IDE works. And support is always ready to help:)
