Why Amazon's resume screen is built around Leadership Principles
Amazon's recruiters scan ~7 seconds and explicitly grade Leadership Principle signals during the screen, not just at behavioral interview time. Resumes that don't pre-signal which LPs your work demonstrates fail the screen even when technical bar is met. The 16 LPs aren't a behavioral nicety — they're the explicit rubric.
Three signals matter most for SDE1-3 screening: (1) LP-tagged bullets — 2-3 LPs per role embedded in bullet parens, earned by the work shown not just claimed; (2) AWS-native stack depth — specific service names (Lambda, DynamoDB, S3, Kinesis), not generic 'cloud'; (3) operational ownership — on-call rotation, SEV management, cost optimization, reliability outcomes. Bullets without all three at SDE2+ fail screening.
