Meta Applied Scientist (Mid-Level) Interview Preparation Guide

Meta's Applied Scientist interview process for mid-level candidates consists of an initial recruiter screening followed by a technical phone screen and a full-day onsite loop of 4-5 interviews. The process evaluates your ability to conduct applied research, develop novel algorithms, implement solutions at scale, and communicate findings. Each round assesses different competencies: research reasoning, technical implementation, ML systems design, experimental validation, and cultural fit. Meta values candidates who can bridge research and engineering by taking abstract problems and delivering production-ready solutions.
