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 Junior Fullstack Developer roles, progressing from initial recruiter screening through multiple technical evaluations (coding, system design fundamentals, and platform-specific skills) to behavioral assessments. The process evaluates coding proficiency, fullstack understanding, problem-solving approach, cultural fit, and learning potential. At the junior level, interviewers assess foundational competency, collaboration skills, and ability to write clean, maintainable code under guidance.
