This guide is based on general FAANG interview practices and may not reflect specific company procedures.
FAANG companies typically conduct 5-7 interview rounds for mid-level MLE positions, spanning 4-6 weeks from initial screening to offer. The process is structured to assess technical depth in machine learning and software engineering, system design thinking for production ML systems, coding proficiency, and cultural fit. Rounds progress from recruiter screening through technical phone screens to on-site/virtual interviews including coding assessments, ML system design, and behavioral competencies.
