When I've run 5e, I've run the Social Interaction resolution mechanics as a combination of a mini Wheel of Fortune + Pictionary puzzle/pantomime game, which I believe to be their intent. Its actually extremely good design and coherent with a game that is, not wholly but certainly significantly, about puzzle solving. I'm confident this was intentful design.
NPC has a concrete Ideal, Bond, Flaw, Trait n, x, y, z.
The player's and GM interact to try to "draw the picture/put letters on the board". Eventually, if the players uncover IBFT's those are used as action resolution leverage for the players to attempt to solve the puzzle (which is the win condition for the social interaction) to get some or all of what they want.
