Firmware Engineer Interview Questions

2,358 firmware engineer interview questions shared by candidates

Two back-to-back panel sessions, two interviewers each. First was firmware architecture and system design, solid, relevant discussion. Second was a whiteboard coding session, the main one being a concurrency problem (spotting a race around a shared variable read-modified-written in an ISR/thread context). Fair question for a firmware role. Overall the technical bar was fair. Just be ready to code and reason out loud at a whiteboard under pressure.
