Reviews
Amazon’s flagship products and platforms (Prime Video, Alexa, S3, DynamoDB) must stay lightning-fast and reliable for hundreds of millions of customers worldwide. As such, System Design is the backbone of day-to-day engineering work, company culture, and — because Amazon only hires the best — the interview process. Amazon dedicates a focused 45-60 minute onsite round (often led by a skilled interviewer from a different team — they call these ‘Bar Raisers’) to gauge your skills. They’ll probe how you would architect real-world services such as a streaming pipeline for Prime Video, an order-processing workflow for Cyber Monday, or a global object store like S3. Interviewers test your requirements gathering, capacity estimates, trade-off reasoning, and leadership-principle alignment.
