Meta Data Scientist Interview Preparation Guide - Mid Level (2-5 years)

Meta's Data Scientist interview process for mid-level candidates consists of an initial recruiter screening round followed by a full-day on-site interview with four distinct technical and behavioral components. The process evaluates your ability to solve complex data problems, design rigorous experiments, define meaningful metrics, and communicate insights to cross-functional teams. As a mid-level candidate, you are expected to demonstrate ownership of end-to-end projects, contribute meaningful insights to ambiguous product questions, and show potential for mentoring junior team members.
