Nothing to put under Skills? Start here.
A thin resume is the hardest one to send, and “familiar with Linux” is the line everyone writes and nobody can defend. Each track here is a set of short quizzes on what a screening round actually reaches for. Work through one and you have a skill you can put on the CV and answer questions about — which is the part that survives the interview. 4 tracks live, 40 quizzes in all.
No lessons and no hours to sit through — ten questions at a time. Every answer comes with an explanation and the source it came from, so you can check us.
Linux Fundamentals
The Linux an interviewer actually asks about.
Networking Basics
What happens between the browser and the server, in the detail a round expects.
Docker and Containers
Images, layers, volumes and networks — and why the container works on your laptop.
Git and Version Control
Rebase, merge, reset, reflog — and which one to reach for under pressure.
