Amazon Data Engineer Interview Preparation Guide - Junior Level

Amazon's Data Engineer interview process for junior-level candidates consists of 6 rounds spanning approximately 4-6 weeks. The process begins with a recruiter screening, followed by a technical phone screen focusing on SQL and data modeling fundamentals. Candidates who advance proceed to a 4-round onsite interview loop (conducted virtually or in-person) that evaluates technical depth through two dedicated technical rounds, system-level design thinking, and behavioral alignment with Amazon's Leadership Principles. The entire process assesses both coding proficiency and ability to reason about data systems at scale.
