I applied through an employee referral. The process took 7 weeks.
2 indoor interviews with team-lead and group-lead, went good overall, basic questions such as bit operations, mid level leet code, every interview ended in a positive mood, seemed the interviewers were pleased overall. I received a rejection by mail with no explanation or reason, after a week and a half. The overall process time was a month and a half since applying. I guess Nvidia doesn't have the time or resources to explain what went wrong....
The following metrics were computed from 21 interview experiences for the Nvidia Firmware Engineer role.
Nvidia's interview process for their Firmware Engineer roles is extremely selective, failing the vast majority of engineers.
Candidates reported having very good feelings for Nvidia's Firmware Engineer interview process.
