DoorDash's general engineering interview process typically includes a recruiter screening, technical phone screens, and onsite rounds. For an embedded developer role, expect rounds focused on embedded systems fundamentals, hands-on coding with C/C++, hardware-software integration concepts, real-time systems understanding, and behavioral fit. Junior-level interviews emphasize foundational competency, learning ability, and collaboration with hardware engineers rather than advanced architectural decisions.
