Apple Data Engineer (Junior Level) Interview Preparation Guide

Apple's Data Engineer interview process consists of 6 rounds spanning 3-6 weeks. It begins with a recruiter screening to assess motivation and foundational data engineering knowledge, followed by a technical phone screen testing SQL, ETL concepts, and basic programming skills. Candidates then progress to a 4-round onsite interview including technical coding, database design, system design, and behavioral assessment. For junior-level candidates, the focus is on demonstrating solid technical fundamentals, hands-on experience with data infrastructure, learning ability, and cultural alignment with Apple's privacy-first approach to data engineering.
