This guide is based on general FAANG interview practices and may not reflect specific company procedures.

Staff-level Data Engineer interviews at FAANG companies follow a rigorous multi-stage process designed to assess deep technical expertise, architectural thinking, system design proficiency, leadership capabilities, and strategic vision. The process typically spans 4-6 weeks from initial contact to offer and includes screening rounds, multiple technical assessments covering SQL/data manipulation, pipeline design, large-scale system architecture, behavioral evaluation, and final bar raiser rounds. At the Staff level, interviews place heavy emphasis on your ability to design systems that scale to billions of records, mentor junior engineers, drive technical decisions across teams, and contribute to long-term data infrastructure strategy.
