In case you were having difficult guessing, I'm minded to agree with tptacek. (And not just because of my sibling comment, in which I admit that my home network is indistinguishable from that of a 90 year old technophobe who got his not-daft-but-still-technically-ignorant grandson to set it up for him.) Is the interviewee's home network, assuming they even have one, really relevant?
If they're going to be setting up a network for you, wouldn't you rather they had experience doing something significant on a professional basis, not just setting something up at home?
If they're going to be doing something else, what relevance does any of this have?
The fact that you are being defended shows that HN is a echo chamber that ultimately supports bullies like you even if they break the rules.
On the other it’s fine if you agree with tptacek’s intent but you were more clear and civil with your point. Tptacek’s comment comes off as pretentious and insulting, and doesn’t promote good faith discussion.
