Getting the interviewer to be _attentive_ is already a given since you've earned the timeslot. Getting them _alarmed_ is what happened here. Showcasing a fighting spirit to stir up some emotional investment.
Though I doubt airing out even the perfect greivance there would've been enough to flip the decision. The growth story just doesn't seem to track.
Also helps that the frustration was aimed at a personal matter instead of directly at someone in the room.

"Polyhedron Navigator" has quite the interesting energy and sound design to it.
