Amazon Interview Loop
Amazon's interview is uniquely LP-driven — every round is evaluated through the lens of 16 Leadership Principles, and STAR format is mandatory in every answer. Coding rounds integrate LP questions alongside algorithms, and system design expects AWS-scale distributed thinking. The loop ends with the Bar Raiser — an independent interviewer who votes solely on whether you raise the bar, separate from your hiring team.

Common questions about Amazon interviews
What is Amazon's Bar Raiser round?
The Bar Raiser is an Amazon employee trained specifically to maintain hiring standards — they are not on your hiring team and vote independently. Their focus is whether you raise the company's bar, not whether you're a good team fit. They probe Leadership Principles deeply, especially Ownership, Deliver Results, and Dive Deep. A Bar Raiser can block a hire even if the team wants you.
How important are Leadership Principles in Amazon interviews?
Extremely important — they are the entire evaluation framework. Every round scores you against specific LPs, and every behavioural answer must follow the STAR format with a clear outcome. Having 2–3 strong personal STAR stories that map to LPs like Customer Obsession, Ownership, Bias for Action, and Deliver Results is essential before any Amazon interview.
How many rounds does Amazon interview have?
Amazon typically runs 5 rounds: HR Screen → Online Assessment → Loop Coding → Loop System Design → Bar Raiser. The last three rounds are often held in a single day (the "Loop"). Some senior roles may include additional leadership or domain-specific rounds. All rounds include LP-based behavioural questions alongside technical content.
