Préparation à la négociation salariale : stratégie d'ancrage, BATNA et scripts d'objection en un seul prompt

Pourquoi ce prompt est important
Professionals who skip negotiation on their first offer at a new company leave an average of $5,000–$20,000 per year on the table — a gap that compounds because future raises are calculated as percentages of the base. Most people don't fail because the company refuses to negotiate. They fail because they open with a weak anchor, fold at the first objection, or don't know their BATNA well enough to hold the line when the recruiter says 'this is our best offer.'
À quoi nous l'utilisons
You just received a job offer and have 24–48 hours to respond. You want to negotiate but don't know where to open, what to say when they push back, or how to use your competing offer without sounding manipulative. Paste the offer details and your situation into this prompt and walk into the conversation with a full playbook.
Prompt
Act as a senior compensation consultant and negotiation strategist with 15 years of experience helping professionals negotiate job offers, promotions, and contract renewals. Context: - Current role: [YOUR CURRENT TITLE AND YEARS OF EXPERIENCE] - Current total compensation: [CURRENT BASE + BONUS % + EQUITY / RSU VALUE] - Target company: [COMPANY NAME] - Offer received: [BASE SALARY OFFERED] + [BONUS %] + [EQUITY GRANT OR RSU SCHEDULE] - Market data you have: [PASTE DATA FROM LEVELS.FYI / GLASSDOOR / BLIND / YOUR RECRUITER — OR STATE "none available"] - Your BATNA (best alternative to a negotiated agreement): [YOUR NEXT-BEST OPTION — COMPETING OFFER, STAYING IN CURRENT ROLE, FREELANCE, ETC.] - Non-negotiables for you: [ANYTHING YOU REFUSE TO COMPROMISE ON — E.G. REMOTE POLICY, TITLE, START DATE] - Negotiation style preference: [COLLABORATIVE / ASSERTIVE / DATA-DRIVEN] Task: Produce a complete negotiation preparation package covering: 1. Anchoring strategy: the exact number to open with and why (apply the 15% buffer rule above market midpoint, adjusted for seniority and location) 2. Justification narrative: 3-4 bullet points connecting your specific experience and proven results to their specific role requirements 3. BATNA analysis: how to signal you have alternatives without lying or revealing too much — in 3 sentences 4. Negotiation script: an opening statement, the 3 most likely objections they will raise, and verbatim response scripts for each 5. Follow-up email: a draft to send within 2 hours of the verbal conversation to confirm changes and create a paper trail — ready to copy-paste with [BRACKETED] fields 6. Red-lines checklist: 3 specific conditions under which you should walk away from this offer Constraints: - Every script line must sound natural when spoken aloud, not rehearsed - Do not suggest fabricating competing offers or inflating compensation numbers - Optimize for total compensation (base + equity + bonus + benefits + flexibility), not just base salary alone - If the offer is already at or above market, reframe the negotiation toward equity cliff, signing bonus, title, remote policy, or start date - Assume the recruiter has seen every trick — prioritize authenticity over cleverness Output format: Use a numbered section header for each of the 6 deliverables above. Format negotiation script exchanges as: [THEM]: "..." → [YOU]: "..." on separate lines. BATNA analysis as 3 plain sentences. Email draft in a fenced block with [BRACKETED] placeholders clearly marked.
Résultat
1. Anchoring Strategy
Your offer is $145,000 base with a 10% target bonus and $80,000 in RSUs vesting over 4 years. Levels.fyi shows P4 engineers at this company median at $158,000 base. Your anchor: $175,000 base. This is 10.8% above market median — aggressive but defensible given your 6 years of directly relevant distributed-systems experience and the fact you're coming in at a level above your current title. Opening at $175K gives you room to land at $162–165K and still outperform the median.
2. Justification Narrative
- You've shipped two services handling >50M requests/day at [CURRENT COMPANY] — directly comparable to their stated scale requirements in the JD.
- Your last project reduced infrastructure costs by 34%, which maps to their public focus on cost efficiency in the engineering blog.
- You have production experience with their exact stack (Go + Kubernetes + Postgres), meaning no ramp-up period.
- You're interviewing with two other companies at the same level — which signals market validation of your experience tier without naming specifics.
3. BATNA Analysis
Your BATNA is a second offer at $155,000 base from [COMPANY B], which you expect to receive within the week. You don't need to name the company — signaling that you are "in final-stage conversations with another company at a similar level" is both true and sufficient. If this offer doesn't move above $160K total base, your alternative is financially comparable and you should take it.
4. Negotiation Script
[THEM]: "We're excited to extend this offer at $145,000."
→ [YOU]: "I'm genuinely excited about the role and the team — the distributed systems problems you're working on are exactly where I want to spend the next few years. I'd like to discuss the compensation. Based on market data for this level and location, and given my directly applicable experience, I was expecting something closer to $175,000. Is there flexibility to get there?"
[THEM]: "That's above our band for this role."
→ [YOU]: "I understand bands exist for a reason. Can you tell me where I'd land in the band, and whether there are ways to make up the difference through equity or a signing bonus? I want to find a structure that works for both of us."
[THEM]: "We've already given you our best offer."
→ [YOU]: "I appreciate the transparency. I'm in late-stage conversations elsewhere at a similar level, and I want to join your team — but I need the total package to reflect my market value. If the base is fixed, let's look at the equity schedule or a one-time signing bonus to close the gap."
5. Follow-Up Email Draft
Subject: [YOUR NAME] — Compensation Discussion Follow-Up Hi [RECRUITER NAME], Thank you for taking the time to discuss the offer today. I wanted to follow up in writing to confirm where we landed: - Base salary: $[AGREED FIGURE] - Target bonus: [BONUS %] - Equity: [RSU GRANT AND VESTING SCHEDULE] - Signing bonus: $[AMOUNT IF APPLICABLE] - Start date: [DATE] - Remote policy: [POLICY AS AGREED] I'm excited to move forward and look forward to receiving the updated offer letter reflecting these terms. Best, [YOUR NAME]
6. Red-Lines Checklist
- Walk away if the final base offer is below $155,000 AND there is no signing bonus or equity top-up to compensate — your BATNA is financially equivalent.
- Walk away if the equity cliff is longer than 12 months with no acceleration clause — at your seniority, a 1-year cliff is market standard.
- Walk away if they won't confirm the remote policy in writing — verbal agreements on remote work have not held up historically, and this is non-negotiable for your situation.
Collez votre offre, vos données de marché et votre BATNA dans ce prompt pour obtenir un package de négociation complet : le bon montant d'ouverture, des arguments justificatifs, des scripts de réponse aux objections et un e-mail de suivi prêt à envoyer — pour ne plus laisser d'argent sur la table.
Le problème que ce prompt résout
Les professionnels qui sautent la négociation sur leur première offre dans une nouvelle entreprise laissent en moyenne 5 000 à 20 000 dollars par an sur la table — un écart qui s'aggrave car les augmentations futures sont calculées en pourcentage du salaire de base. La plupart des gens échouent non pas parce que l'entreprise refuse de négocier, mais parce qu'ils ouvrent avec un ancrage faible, cèdent à la première objection, ou ne connaissent pas assez bien leur BATNA pour tenir bon quand le recruteur dit « c'est notre meilleure offre ».
Quand l'utiliser
Vous venez de recevoir une offre d'emploi et avez 24 à 48 heures pour répondre. Vous voulez négocier mais ne savez pas par où commencer, quoi dire quand ils résistent, ou comment utiliser une offre concurrente sans paraître manipulateur. Collez les détails de l'offre et votre situation dans ce prompt et entrez dans la conversation avec un plan d'action complet.
Comment le prompt est structuré
Le prompt suit une structure Rôle + Contexte + Tâche + Contraintes + Format de sortie. Le Rôle positionne le modèle comme un consultant senior en rémunération — pas un assistant générique — ce qui oriente les réponses vers un cadrage stratégique plutôt que des banalités. Le bloc Contexte est entièrement entre [CROCHETS], vous remplissez donc vos chiffres spécifiques plutôt que de recevoir des conseils génériques.
La section Tâche demande six livrables concrets : un montant d'ancrage avec justification, un récit argumentatif lié à la description de poste spécifique, une analyse BATNA, un script de dialogue textuel, un e-mail de suivi prêt à copier-coller, et des lignes rouges explicites. Le bloc Contraintes empêche le modèle de suggérer des tactiques malhonnêtes et l'oriente vers l'optimisation de la rémunération totale plutôt que du seul salaire de base.
Compatibilité des modèles
Ce prompt donne les meilleurs résultats sur Claude Sonnet 4.6 ou GPT-4o, qui suivent tous deux des instructions structurées multi-livrables de manière fiable. Claude produit généralement des scripts de dialogue plus naturels ; les brouillons d'e-mail de GPT-4o sont légèrement plus formels. Gemini 1.5 Pro fonctionne mais réduit parfois la structure en 6 sections à un texte continu — ajoutez « Vous devez utiliser exactement les en-têtes de section numérotés comme spécifié » si cela se produit.
Conseils pour de meilleurs résultats
- Collez des données salariales réelles provenant de Levels.fyi ou Glassdoor dans le bloc de contexte — plus les chiffres sont précis, plus l'ancrage produit par le modèle est défendable.
- Si vous n'avez pas d'offre concurrente, indiquez honnêtement votre BATNA (rester dans votre poste actuel, travail en freelance, etc.) — le modèle travaillera avec cela sans inventer une fausse offre.
- Exécutez le prompt deux fois avec des préférences de style de négociation différentes (assertif vs collaboratif) et comparez les scripts — ils diffèrent de manière significative.
- Après la conversation, revenez et collez ce qui s'est réellement passé pour obtenir un débriefing et un e-mail de suivi révisé si le résultat verbal a différé du plan.
