About the test

The Linux online test assesses knowledge of the Linux operating system, its kernel, and programming Bash scripts. This test includes live coding tasks that are executed on the Ubuntu server.

The assessment includes work-sample tasks such as:

  • Managing permissions and authorization to prevent misuse of resources.
  • Partitioning disks to control how data is stored and retrieved in a file system.
  • Writing Bash scripts to automate tasks.

A good backend developer or Linux system administrator should be familiar with Linux as it's the most widely used server operating system.

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.
