In the story, character A has separate conversations at different times with characters B, C, and D. The film presents this as one sequence, cutting to A for their remarks and then to B, C, or D for their replies, and it all sensibly links together like one conversation. Is there a specific name for this technique?
I found some possibly applicable general terms (I didn't just search Wikipedia, but I couldn't find anything useful elsewhere).
Montage "a series of short shots are sequenced to condense space, time, and information" seems to cover it in a general way?
Cross-cutting "most often used in films to establish action occurring at the same time, and often in the same place, ... the camera will cut away from one action to another action, which can suggest the simultaneity of these two actions but this is not always the case" I am not so sure about?
For example, in the murder mystery "Knives Out", the police interview members of the family in the library room, and we cut between the policeman in one chair and the other chair where the interviewee sits. The interviewee says something, we cut to the policeman to reply, then cut back, and it's a different interviewee replying back to that.
In the script, this is shown with the directions "Cut to: A in the chair", or simply "B in the chair", or similar.
Is there a specific name for this technique?
(Here's a sample example part of the script, heavily edited for relevance. In the story, Elliot is interviewing each person separately, one after another; this has been established by earlier dialogue.):
Mystery and horror memorabilia scattered on the shelves. Joni sits opposite: LIEUTENANT ELLIOTT
JONI If I could - pause - because I, who is that guy? And why are we doing all this? Again?
LIEUTENANT ELLIOTT Right. We're following up here, just being thorough, in order to determine the manner of death.
Cut back to Walt in the chair.
(what?) The manner of death? I can save the taxpayers some money here - Walt gestures vaguely to his throat.
That's the cause of death. The manner of death is still pending.
So by "manner of death" you mean if he was killed. If one of us killed him. One of his family?
None of us think that, this is proforma, all of it.
CUT TO: Richard in the chair. He doesn't buy it.
Ok. So who the fuck is that?
He points at linen suit. Elliott takes a breath.
Mr. Blanc is a private investigator of great renown.
Joni in the chair.
Wait a minute - I read a tweet about a New Yorker article about you.
Mr. Blanc requested to sit in on the questioning and I happily consented. I can vouch for him.
Linda in the chair.
Oh you vouch for him...
