When I get stuff like that, I'm generally like "oh wait I'll try a real company". Not that C is not lower level for example. I love C. But since the interviewers are actual devs and managers at Google, it shows quite a bit.

I'm guessing it'd be nice starting writing in a lesser known language or even just go for some old arch object code (like 68k object code which is pretty simple to write, and the chance is high that the interviewer will be clueless and find this a bad joke - and yes i can write that as i did a lot of it 15years ago, its straight forward)

Then Google writes you as an "do not employ" person of course and say that you do not fit (while you declined them), but hey, honesty, balls, and being dumb sometimes feel good. Sounds like a true story.. oh, I know.
