Obviously it depends a little bit on what the job actually entails
(database admin? web stuff? backups? performance tuning? jack of all
trades?), but I find in general that the best questions focus on
candidate experience and problem solving abilities rather than
- How would you rate your Linux skill on a scale from 1-10?
- Name some Linux commands.
Basically, anything you can answer with a textbook or Google, or
anything subjective where the applicant is making the judgement call
aren't very useful.
- Can you tell me about a project you're particularly proud of, did
particularly well, etc. Ask questions to whatever level of detail
- I have a mixed network of Linux and Windows machines. How would you
back them up? I have a website setup, what would you do to improve
All of those are pretty open-ended questions, but they let the
candidate demonstrate how deep their knowledge of a subject area is,
their competence, and their communication abilities. If they don't
know the answer to a question, ask them where they'd go from there.
Get them talking and it will both put them at ease and likely make it
pretty easy to judge how good they are.
Side note: Any of those positions still open? ;)
Disclaimer: This is all just my opinion. I am not, and have never been
in the position to hire anyone.
