I interviewed there as an SRE many years ago (early-mid 2000's) and I was asked about mathematical algorithms, whether I'd published any books in tech, and what open source I contributed to.

I would have needed to study for a year or more of math since I never studied math in college, and I wasn't just out of college. Even someone with a computer science degree, once they've been a professional for a few years, would need to crack open college textbooks again to pass a Google interview.

Unless they did math as a hobby, which I will refrain from commenting on at this time.
