Google

First-round Hangout interview with someone SWE-based in Zurich. This typical Google interview consisted of one warmup question (coding using Google Drive) and one open-ended question. We discussed file system concepts, involving basic data structure

I was referred by a friend and first approached by a recruiter from Google. They asked for some basic information, and then I had a phone screen. The interview problem was hard for a phone screen, but I can't complain; Google sets the bar high.

3 rounds of DSA and 3 rounds of C++ questions asking. Then an HR interview round. Then projects asking, and asking about OS and database system process.
