Everyone knows that is the move. Almost nobody manages it live, because four seconds of silence in a real conversation feels like a minute and you will want to fill it.
They have chosen you, they have told other candidates no, and they would rather pay you more than start again. That is as strong as your position gets, and it lasts about one conversation.
What usually spends it is a reflex: "what are you looking for?" answered honestly and early, or a number given with a reason attached that immediately invites a counter-reason. This gives you a hiring manager who asks first, who does not blink at your figure, and who lets the silence sit there to see what you do with it.
You name the role and the number
The job, the offer on the table, and what you actually want. Be specific. Vagueness here becomes vagueness in the room.
You talk, out loud, and they push back
Your voice, not typing. They answer in real time and they do not simply agree. Expect to be asked your number first, and expect the pause after you give it.
You see where you went reactive
A debrief on the specific moments where you negotiated against yourself, justified the figure unprompted, or filled a silence that was working for you.
You need a microphone, somewhere you can speak freely, and six to ten minutes. Chrome, Edge and Safari can do this. Firefox cannot yet.
Your voice never leaves your device. Your browser turns your speech into text on your own machine. The audio is not uploaded, not stored, and not heard by anybody.
The other person is an AI. Not a recording, and not a person listening in. It answers in a synthesised voice and it will push back.
No signup. Two full rehearsals, free, and nothing to create before you begin.
