Interviewed with a total of 11 people (11 total man-hours spent for a single candidate!) for onsite + phone.
The only feedback was that the team was looking for someone else with more experience in a certain non-embedded area, despite passing all the technical interviews and being rejected by the HR one (though they didn't mention this part).
Beware the hidden anti-poaching deal that is practiced between large US-based companies in Bucharest.
I applied online. The process took 6 weeks. I interviewed at Fitbit (San Jose, CA) in Feb 2023
Interview
Asked some basic RTOS questions, interrupt concept, etc. Then asked to write a piece of code to reverse a string. Then asked to write a code to detect whether an integer is 2^n or not.
