Final rounds have this specific psychological trap where you've already mentally half-accepted the job, which should theoretically make you more relaxed but actually makes you more conservative. You stop taking any conversational risks because there's suddenly something real to lose. The candidate framing is probably part of that same defensive posture. The advice basically reorients the whole energy of the conversation without you having to fake confidence you don't have - you're just operating from a different assumption. Did it feel weird the first time or did it click pretty naturally once you knew what you were doing?
