I think if you define interviewing in the strictest sense, then sure. But personally I find this all pretty applicable. I do far better in conversation (with strangers) when I apply most of this. One of the best pieces of advice I was ever given was "nobody cares about you, but everyone loves speaking about themselves". If you can get someone to open up and _start_ talking, and you are genuinely curious without seemingly like you're looking for an opportunity to talk about yourself, in my experience that person goes away with a generally positive opinion of you.

I suppose you could also argue that any conversation with someone new IS an interview - be it date, work, new friend. Ultimately you're checking as to whether you want a second encounter with that person, right?
