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

Entry-level cryptographer positions at FAANG companies typically follow a structured 6-round interview process designed to assess foundational cryptographic knowledge, mathematical problem-solving abilities, coding proficiency, and cultural fit. The process emphasizes learning potential, clear communication, and ability to work on cryptographic problems with guidance. Entry-level candidates are not expected to have production-level cryptography experience; instead, interviews focus on strong fundamentals, mathematical reasoning, and potential to grow into the role.
