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.
Sample public questions
The weather.sh utility in the current working directory provides weather forecasts in your area.
When called, it outputs a 4-day forecast in the format "day: weather" separated by line breaks.
Write a bash script that outputs the number of days with a "Thunderstorm" forecast (case-sensitive).
See the example case for more details.
Your company has a Linux computer with a directory named debug_programs intended for developers only.
The following needs to be done:
- debug_programs should only be accessible to users in the developers group.
- Alex should be removed from the developers group because he left the company.
- Confirm that the new developers Cynthia, Emma, and Justin belong to the developers group.
What should be done to satisfy the requirements above?
You ran a script that wrongly put its output image files in the 'work' directory inside the current directory.
Create a bash script that removes all the files in the 'work' directory that start with either 'out_0' or 'out_1' and end with '.png'.
For example, if the 'work' directory contains the following files:
After running your script, both out.png and out_0.pdf should exist in the 'work' directory but out_0a.png and out_1.png should no longer exist.
See the example case for more details.

What others say
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.
