For an entry-level interview, it is generally **easy to get through one round** if you prepare the **basic topics** well. Focus on **Linux fundamentals**, such as common commands (`ls`, `cd`, `grep`, `chmod`, `ps`, `top`), file permissions, processes, and basic networking. You should also know **server hardware parts identification**, including CPU, RAM, hard disk/SSD, power supply, NIC, RAID, and cooling components. Be ready for **resume-based questions**, where interviewers ask you to explain projects, tools, and technologies you have listed. Clear explanations and basics are usually enough.
I applied online. The process took 1 week. I interviewed at Jabil (Dublín, Dublín) in Sep 2019
Interview
Very simple, no technical questions (which is their big mistake). The job requires skilled people to troubleshoot servers but they do not hire skilled people.
You won't be trained, they will let you with the old members of the team (which at the moment are very bad) and you have to find everything on your own, if you have Skills you will be fine otherwise you are screwed.
