Hi guys,
I'm having an interview tomorrow for a job in home network support at Telus Mobility. I'm kinda stressed cause I'm not a network guru at all. What questions could they ask me? What should I absolutely study before getting there? Any help would be greatly appreciated!

Thanks....

If i were interviewing you , i would asking question such as:

- what is your knowledge about network, understanding of the network type and devices, CPE, DSLAM, Concentrator, RADIUS Server, etc
- How do you troubleshoot this network when problem arises, ping utility, traceroute, etc
- programming language (simple language only) understand code
- Help people on the phone, how confident are you solving these network problem.
- About yourself, are you a bad person at all

Well, another thing to know is how to get answers to questions you don't know.  I've been doing IT work for 10 years, but I still run into new problems every week.  Sometimes I figure them out on my own and other times I'll search the web for help.

When I have interviewed people in the past, I thought it was a good trait when people said they don't know everything, but they do know how to get answers.  You can take just about any error message and "google it" to find more info.  This site is a great tool for getting quick answers to problems.  As you discovered, just post a question with a good amount of points and you'll get people jumping at the chance to respond.

You might also want to check out sites like this:

http://www.tomsnetworking.com/FAQ.php

They have info on various network products, including answers to common questions (hence the FAQ link).

Just be confident that you can find the answer to any problem and keep this site a secret until after you've been in the job for a while. ;)

I can weed out 80% of potential candidates for most IP-related technical postitions with one question:

"Tell me about netmasks"

It often reveals about how much they understand the difference between local and routed subnets, routing fundamentals, subnet (and binary) math, and IP fundamentals in general.  If they don't mention ARP, routing tables, subnet divisions, or CIDR I generally give them a pass...

Cheers,
-Jon

Heres the 1,000,000 question I would ask just such an applicant.

Tell me how you qualify for this position.

Keep in mind folks, this is a position for Home Networking Support, probably for a broadband provider.  He'll only need to know the end-user portion of things to start out.

The netmasks question has my vote as the best disqualifier. I am an AI for a series of classes on network and computer security, and we kill people's averages with two sections: subnetting, and secure router configs... :D

>Tell me how you qualify for this position

is a good one, but I find too many people are prepared to BS their way through such a question.  The one about netmasks is quite difficult to fake - it generally hits directly home to the amount of knowledge an IP tech possesses.

Cheers,

I strongly suspect that home network support organizations would have a much better reputation if more of the people hired for such operations could answer the subnet masks question.....

Thanks a lot for all your help guys, I got the job ;-)

As you said Jeff, the most important thing is knowing how to get solutions for your problems. I have always been a power-googler so I usually get the answers I want ;-)
