8,704 network engineer interview questions shared by candidates

Round 1 was split into 20 apti stuff , 10 problem solving stuff and 20 tech stuff, which further can be drilled down as 10 from Micropocessors , Networking etc and rest 10 from usual programming on C , C++ and Java Round 2 was basic technical round where in I was asked about the OSI Layers , Difference between routing and switching , MAC Addr and IP Addr , and explain the full process of how a packet is moved from source to destination including DNS Lookup , Routing protocols that I would suggest etc etc . I personally suggest "Computer Networking A top down approach" 6th Edition by Kurose and Ross would be the best book . Round 3 was the most rigorous HR round I have ever been in ; The panel consisted of 2 men ; Since this is for a role that Cisco would use to face a customer mostly they were all management oriented questions , The interviewer asked me a few tech questions until I ran out of answers and asked me what would I do If the same thing happens on a presentation with the customer . I was not confident enough to tell him I would ask some time and get back with the answers ASAP . The HR was just expecting a confident reply from me . so what I would suggest is to reply confidently even if you are with the wrong answer tell him that I am not sure of this answer but I will get back with the right ones ASAP . Never go for a HR round unexpectedly , stay cool , know when your turn would probably come and never panic or get nervous in an HR round . All your efforts on clearing the first few rounds would go to drain if you flunk in the Final HR Round . So whatever condition you are get back to normal , keep smiling & be confident and you can easily crack Cisco Systems for sure .. All the best ..!!
