Meta Data Engineer Mid-Level Interview Preparation Guide

Meta's Data Engineer interview process for mid-level candidates (2-5 years experience) consists of 7 rounds spanning 4-6 weeks. The process begins with a recruiter screening, followed by two technical phone screens focused on SQL and Python proficiency, and concludes with four onsite rounds covering data modeling & schema design, ETL pipeline architecture, product sense & metrics, and behavioral/cultural fit. The interview evaluates technical depth across core data engineering skills, ability to design scalable systems, product understanding and business acumen, and alignment with Meta's values of moving fast, data-driven decision making, and cross-functional collaboration.
