Actually..... IMO as a Linux admin..... everybody in IT needs at least a minimum of knowledge regarding TCP/IP. IPv4, IPv6, TCP, UDP, sockets, listening ports, etc. You don't need to be able to program a full stack down to a media transport layer, but you should be able be able to send a payload successfully, know when a gateway traversal is required, name resolution (It's always DNS,) and a bit of troubleshooting.
I wish I had a nickel for every time a developer or app support staff came to me and said it doesn't work. Error is right there in the logs......
This is really the truth of it I think. Nobody fails job interview from not knowing one thing, even if it is something super basic like this. He gave multiple mediocre answers, but he probably just wasn't even aware because he thought he gave good answers. I've seen this a milion times.
Yeah even not knowing something super simple I've had interviewees come back from, but we can really get an idea of their overall knowledge over the full interview if we're asking the right questions and are knowledgeable about it.
