Technical: 1)What is OSPF & what messages do they send? 2)Do you know what nat is? 3)What are the different spanning tree versions? What is spanning tree for? 4)What is the cisco hierarchical/three teir model? Then there are some troubleshooting questions. Just how you would troubleshoot pretty much. Also process questions about what you bring to the team and what changes youd make and what ambitions you have. Overall not a difficult one. The technical ones are okay. Its the process/troubleshooting ones that are more difficult.
