Behavioral Onsite - Amazon Leadership Principles
What to Expect
A 45-60 minute behavioral interview where the interviewer asks 2-3 behavioral questions designed to assess alignment with Amazon's 16 Leadership Principles. Each question typically targets a specific principle such as Dive Deep, Deliver Results, Ownership, Customer Obsession, or Earn Trust. You'll describe situations where you've demonstrated these principles, using the STAR method (Situation, Task, Action, Result). The interviewer probes for depth, asking follow-up questions about challenges, what you learned, and how you measured success.
Tips & Advice
Prepare 5-7 strong stories covering different Leadership Principles, each with a clear situation, task, action, and quantified result. For mid-level, emphasize examples where you owned a project end-to-end, made independent decisions, drove results under constraints, and learned from challenges. Highlight collaboration with cross-functional teams and instances where you mentored junior colleagues. Use metrics to demonstrate impact (e.g., 'reduced report latency by 40%', 'improved adoption by 25%'). Be specific, not generic. Avoid reciting textbook answers; instead, share authentic experiences that naturally align with principles.
