I applied through a recruiter. The process took 1 week.
Recruiter call, discussed profile, interests followed by 30 min scheduled interview. Interview questions were embedded specific but needed to get exactly right in limited time. Questions were basic:
Extracting a certain byte range from a given 32-bit value in C.
Implement matrix multiplication in C.
The following metrics were computed from 1 interview experience for the Etched Firmware Engineer role in Cupertino, California.
Etched's interview process for their Firmware Engineer roles in Cupertino, California is extremely selective, failing the vast majority of engineers.
Candidates reported having very negative feelings for Etched's Firmware Engineer interview process in Cupertino, California.
