I just had a Noc interview last week. They saw I had a good Telecommunications background but they asked me four questions in this order.
1.Do I know Active Directory or have I ever worked with it ?
2.Do you have any Linux or Unix experience ? It would be nice if was in Red Hat or Cent OS.
3. what server experience do you have ?
4. Ever troubleshoot a DS3 or T-1 and if so how did you troubleshoot it ?

Answer
1.None of the ISP/NOC positions required me to work with Active Directory. " I am willing to learn thou and I am a fast learner".
2. DO I know Linux or Unix. No not really.
3.What server experience do I have. "none"
4. Ever troubleshoot a DS3 no, Ever troubleshoot a T-1 "yes" and explained how.

Just be your-self and be honest.

Ya i dont reallt have a telecommunications background but have been geting familiar with dwdm,sdh and mpls( which i believe is beyond the scope of the ccna). I will however do my research on it and at least know what it does.

As far as technical questions--

Minimum 2 years NOC/Telecommunications experience

I'd begin by asking you to list/describe your two years of experience if not clear from the resume. I might ask questions to clarify how relevant it was to the environment/role/equipment you are being considered for.

Working knowledge of either Ethernet/MPLS/SDH, preferably specialized in one with a good understanding of the others

I'd then ask which of these you felt was you considered your specialty. I'd dig into that area deeply, in terms of your know-how and experience, and then dig into the other areas lightly.

Proven problem-solving experience within layer 1 and 2 networks

This obviously lends itself to troubleshooting scenarios. Maybe I'd also ask you to identify or describe cable types and components. The role is for someone with only a bit of experience, so nothing too deep.

chickenlicken09

ok keep them coming guys potential questions that could come my way. I will start preparing.

chickenlicken09

network veteran, out of curiosity how would you describe ethernet if asked. As i believe it contains alot of technologies and not just the actual cable.
It would be a bit of a vague question to ask or would it not.

NetworkVeteran

It's a fair question. "It's what's plugged into your laptop. What would you like to know?"

chickenlicken09

haha true

NetworkVeteran

I ask questions. I like to know what their requirements are so I can optimally meet them.

chickenlicken09

ya i know you have got to be able to meet half way. Is there any others you can think of that might be thrown in.

If you claimed Ethernet was your strong area, I might cover--

1. Frame formats - basic, type/length field, LLC, SNAP, tags, etc.
2. Transparent bridging & MAC addresses
3. STP vs RSTP vs MSTP
4. Cables & connector types
5. Auto-negotiation
6. LAGs
7. Tagging
8. Qualify of Service
9. IEEE standards
10. MEF standards

Nice, thanks. Last question, is there much of a difference between network operations engineer and a network engineer.

NetworkVeteran

is there much of a difference between network operations engineer and a network engineer.

I focus on responsibilities more than titles, given how differently various employers title the same role.
