I applied through a recruiter. I interviewed at Google (Santa Clara, CA (US)) in August 2018.
Pretty straightforward and standard. You can find everything about the interview online. Coding interviews need some algorithm knowledge. Basic dynamic programming and some graph would be enough. The system design interview focuses mostly on scalability. The system design interviewer was a highly experienced engineer.
