This guide is based on general FAANG interview practices and may not reflect specific company procedures.
The full stack developer interview process at FAANG companies typically involves 5-7 rounds spanning 4-8 weeks. Mid-level candidates are evaluated on their ability to design and implement complete features across frontend and backend, handle moderately complex system design problems, demonstrate strong problem-solving skills, collaborate effectively across teams, and show clear growth trajectory. Each round builds on previous assessments to evaluate different dimensions: technical depth, system thinking, coding proficiency, and leadership/culture fit.
