About the test

The Linux online test assesses candidates' knowledge of the Linux operating system and its programming using the Bash scripting language.

It's ideal for pre-employment screening. A good backend developer or Linux system administrator should be familiar with Linux as it's the most widely used server operating system.

This online test requires candidates to answer multiple-choice questions about the Linux kernel and its command line utilities.

Decorative quote

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.
