Google's interview process for cryptography-focused roles typically follows a structured pipeline consisting of an initial recruiter screening, technical phone screening round(s) to assess cryptographic fundamentals and problem-solving ability, and multiple onsite interview rounds covering technical depth, protocol design, implementation security, and cultural fit. For a junior-level role, the process emphasizes learning potential, foundational cryptographic knowledge, hands-on implementation skills, and ability to work collaboratively with senior cryptographers and security teams.
