Updated 2/23/2026

The interview process for a Senior Level Applied Scientist follows a rigorous FAANG-style progression designed to evaluate research depth, ML system design expertise, practical implementation skills, experimental rigor, and leadership capability. The process spans 4-6 weeks and consists of 8 rounds: an initial recruiter screen, two technical phone rounds focusing on ML theory and system design, four comprehensive onsite rounds covering advanced ML concepts, experimental design, systems architecture, and behavioral leadership assessment. Each round progressively increases in complexity and evaluates the candidate's ability to bridge theoretical research with production systems, mentor others, and contribute strategic insights.
