TIPS for PREPARING FOR THE INTERVIEW

1. Study- Before you go to you Interview, open the books up and give yourself a general review of networking.
2. Update your Resume - Read your resume and update it. The last thing you need when you are putting your best face forward is to have a resume that is full of grammatical errors.
3. Watch out for Social Networks - Many employers are getting very smart and will search on your name. Be sure if they find your facebook or myspace page there isn't anything there that you wouldn't want them to see.
4. Google yourself - Search for yourself on Google and see what you find. You would be amazed an what might pop up. Make sure nothing derogatory shows up.
5. Get Certified- One of the best things to do to prove you know what your talking about is a certification. This gives a new employer an easy way to understand your knowledge level.

Preparing for NETWORK ENGINEER INTERVIEW QUESTIONS

1. IP Addressing- Make sure you know subnetting (without a subnet calculator!). Know the value of every bit in each each Octet. Know subnet masks and what their slashed notation is and CIDR
2. Memorize administrative distances of all routing protocols.
3. Review the simple stuff, like 3way handshakes in tcp, setting up hrsp, ip helpers, and vlans.
4. Review Spanning Tree - Know what a root bridge is, know what VTP does
5. Review VLANs and be able to explain what a vlan is.

Employers know you can look things up in a pinch but what do you know off the top of your head that you can hit the ground running and fix a problem if it arises. Or if they send you out to a remote location to setup a router, with no internet, can you get the thing online and working?
Put yourself in their shoes, what will they need from you? Review the job description and target those things specific to the job your interviewing for.
