Job interview waiting room..?
It's fine, as long as they're open to it. If they don't appear receptive then don't force it. Some people prefer to sit and think about the upcoming interview and mentally prepare themselves, so don't desire to chat with others while waiting.
No, because you don't know what information you are disclosing to an unknown stranger.
Just keep quiet.
No, up to you whether you chat or not.
i dont think so, thats up to you if you want to talk or not
No I don't think there's anything wrong with that, there's been times I've been waiting and I was sitting next to a couple people while waiting but didn't say much besides hello. You're usually nervous anyway about the interview and not everyone feels like talking. Don't stress about it!
No, not bad.
Does not matter, really.
Nah, they would have been bricking it as well.
