Amazon's Hyperscale Hiring: 90 % Cost Cut – 3× Funnel Precision

Amazon hires over one million hourly associates and 50 000 corporate staff every year, where each missed forecast risks broken customer promises and millions in overtime. This session dissects the data‑science engine that turned talent acquisition from billion‑dollar cost centre into a P&L lever. You will see how centralised bidding fed by external job‑board pricing and labour‑supply indices cut paid media 90 %, how ML scoring compressed applicant‑to‑hire from 11:1 to 3:1, and how 3 000‑site demand forecasting meets 95 % accuracy within three weeks – all under a governance model co‑owned by Finance, Legal and PR.

• Centralised marketing‑spend kill‑switch blending ATS clickstream with external CPC and labour‑supply data.
• ML scoring that moved applicant‑to‑hire from 11:1 to 3:1 while passing bias‑audit economics.
• 3 000‑site demand forecasting framework with 16 adjustable dials and 95 % accuracy in three weeks.

• Governance playbook linking model revisions to P&L, Legal approvals and CSRD‑aligned audit trails.
• Pitfalls faced – vendor outages, local resistance, bias drift – and the remedies that enabled scale.

• Quantify how data‑science interventions can convert talent‑acquisition spend into measurable bottom‑line impact.
• Identify the internal and external data signals required to optimise media spend, funnel precision and demand forecasting.
• Apply a Finance‑first governance model that logs every model revision to the P&L and satisfies Legal review.
• Spot common failure modes – infrastructure outages, stakeholder push‑back, bias drift – and adopt proven mitigations.
• Prepare for next‑generation LLM‑driven matching and assessment pipelines.
