Here are the most popular Linux questions I see (and use) during DevOps interviews.

1:11 - Basic Linux Interview Questions (ssh, ls, cd, cp, pwd, rsync, systemctl, df, du, ip addr, ip route)
4:55 - Slightly more advanced Linux (init, systemd, systemctl, journalctl, some linux philosophy, /proc filesystem)
8:01 - open-ended questions and troubleshooting (top/atop/htop/glances, lsof, /proc, ss or netstat, inodes)
11:05 - discussing past projects, planning a hypothetical implementation/project
