I went through all the questions with 3 other people in the same room all at once about 5-6 years ago. I did not know any of them well. We all became friends and are still friends to this day. It was like magic.
One of the other three suggested it, not sure why, and then we did it.
For each question we would take turns answering it. We were allowed to say, "Pass," if the question made us too uncomfortable or, if we couldn't think of a good answer fast enough, we could pass and come back to it after everyone else had answered.
We were already at the level of acquaintances, close enough to be at the same location, hanging out, but I didn't trust any of them yet, and they barely knew me.
Did you hang out with other groups of people who you're no longer friends with?
I wonder also if it might be commitment to the experience as much as the experience itself that affirms the bond and establishes a platform for ongoing friendship.

Yes? One person in particular, I became friends with them extremely quickly about 2 years ago. There was no contrived questionnaire involved, we just clicked, but after one falling out, the bridge was completely burned.
