Daniel Petri’s MCSE & System Administrator Job Interview Questions – Part 4 – PC Technician

After a long delay, this is a part 4 of my MCSE and System Administrator job interview sample questions.
See previous parts at:

This article set is targeted at both the interviewer (who needs a pool of valid questions they can ask) and the candidate (who wants a pool of sample questions they can prepare for). Needless to say, both MUST know what they’re talking about. Also, although I consider these questions as a thorough verbal test for the candidate’s knowledge, in most cases, when he or she passes this phase, I will also ask them to perform an actual hands-on lab based on my written exercises. As I said before, I might also include these in a future parts of this series.
I wish to thank Shachaf Cohen of John Bryce Training in Israel who has helped me to compile a large part of this article’s questions.
I have deliberately left out the answers to these questions. I want YOU to research them and take the time to actually learn these topics, if you don’t know them already.
Most sub topics start off with relatively easy questions where the candidate is supposed to demonstrate their knowledge on that topic. A few sentences will be enough to show their (lack of) knowledge on the topic.
As always, your comments and feedback are more than welcome. Use the “Comment” form below to send them in. If you’re using this interview question sample in your own environment please drop me a line telling me how it works for you. Also, placing a link to my site and giving me credit for my work is expected.
