DoorDash Staff-Level AI Engineer Interview Preparation Guide

DoorDash uses a decentralized, team-specific interview process for staff-level candidates. The Staff-level AI Engineer interview combines an initial phone screening phase (recruiter and hiring manager rounds) with comprehensive onsite technical rounds. The process emphasizes system design mastery, deep expertise in neural networks and modern AI architectures, practical ML case studies, and cultural alignment with DoorDash values (ownership, impact, speed). Staff-level candidates are assessed on their ability to design large-scale AI systems, mentor junior engineers, and drive technical direction. AI usage during interviews is strictly prohibited but allowed during preparation.
