Google yourself – Search for yourself on Google and see what you find. You would be amazed at what might pop up. Make sure nothing derogatory shows up.
Get Certified – One of the best things to do to prove you know what you are talking about is a certification. This gives a new employer an easy way to understand your knowledge level.
Preparing for Network Engineer Interview Questions
Make sure you prepare well on those technical subjects. Don’t think that you know them already, actually spend time refreshing your knowledge to be and look more confident:
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. Get familiar with wild card masks.
Memorize administrative distances of all routing protocols.
Review the simple stuff, like 3way handshakes in tcp, setting up hrsp, ip helpers.
Review Spanning Tree – Know what a root bridge is, know what VTP does, be sure you can explain the differences with RSTP.
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.
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.
The goal of an interview is to evaluate not only the technical knowledge of the candidate, but also the soft skills, the personality and the behavior. At the end you’ll be working on a team of people and be a good fit for the team is often more important than the technical skills.
Get ready for the non-technical questions and try to be honest and genuine, but also keep it professional. Check the company website to understand what they do and in which market they operate. Read few times the job description to understand what they need and how can you satisfy that need.
Some non technical questions that are often asked are along those lines:
Why did you choose a career as network engineer?
Why you think you can be an asset for our company?
What are your strengths and weaknesses?
Describe a difficult situation you had in your past jobs, how did you deal with it?
Have you ever had conflicts with your colleagues or manager? Why?
Describe a project or work that you’re particularly proud. Why was it a success?
Where do you see yourself in five years? (yes, this is the most hated one!)
