Alright Anons, I had my first technical google interview. It was for an embedded SWE role.
The questions were just some bit manipulation (swap each bit in a var with the bit next to it) and a question messing with a 1d array that represents 2d data.
It wasn't too bad and I think I performed well enough, but the interviewer was an Indian woman and she clearly was not very interested in me. So I'm probably not going to get the next stage.

Ah well, it's always a coinflip.
My applications have been getting more attention lately so I'm not really bothered by it.
