Senior Machine Learning Engineer Interview Preparation Guide - FAANG Standards
This guide is based on general FAANG interview practices and may not reflect specific company procedures.
Senior Machine Learning Engineer interviews at FAANG companies are comprehensive, typically spanning 5-7 rounds over 4-8 weeks. The process assesses deep technical expertise in ML algorithms and optimization, system design for production ML at scale, coding proficiency, leadership capabilities, and cultural alignment. Senior-level candidates are expected to demonstrate not only strong technical skills in model development and deployment but also the ability to design scalable ML systems, mentor others, make architectural decisions, and drive technical strategy. Interviewers evaluate your understanding of the complete ML lifecycle: data pipelines, feature engineering, model training, serving infrastructure, monitoring, and retraining strategies.
