Hi all,
I have been given an interview for a first line support position at a local ISP which will be taking place Tuesday

. Whilst I am already reviewing the common interview questions, can anybody give me some pointers on what technical areas/technologies I should revise in preparation for any technical questions which are asked. I have pasted the relevant parts from the job spec form below.
Our competencies include cloud services, collocation, managed hosting, connectivity, SIP trunking and hosted telephony.This is a fantastic opportunity to build on your data, IP networking and general IT skillsTo be considered for the role, you must have - a good working knowledge of data and IP networking
So far all I can think of is brushing up on my subnetting and general IP networking knowledge.
Any help is much appreciated!
Many thanks
