These are the public demos of The Linux Camp hiring assessments, the same thing employers send candidates. Each demo is a short block of multiple-choice screening questions on real-world Linux, graded on our server, followed by hands-on tasks on a real Linux machine with the clock running. The machine verifies each task as you finish it, every command is recorded, and you get a result page you can share. Free, login required, one run per hour per network.
Ten screening questions (disks, services, permissions, users, cron, networking), then eight hands-on tasks on a real VM: onboard a user, fix a shared folder, lock down a config, bring a broken service back, schedule a job, read a log, free a disk, read the network path.
Eight screening questions on what the tools mean (BMC, SEL, SMART, optics, LLDP, FRU), then a shell on a GPU node with simulated hardware tools (ipmitool, dmidecode, smartctl, ethtool, lldpctl): find the BMC address, the chassis serial, the failing drive and its serial, the optic serial and switch port, the port with no link, the latest critical BMC event, and bring one real systemd service back.
The clock covers questions and tasks together. A real Linux shell on a real VM; where a demo simulates hardware it says so. Every command is recorded. No hints and no AI tutor. Login is required so the machine is yours alone, and each demo runs once per hour per network.
