Google Software Engineer(Internship) interview questions

The interview consisted of 2 technical 45-minute interviews back to back. The format was a quick warm-up question which led to the actual question. In each, there was also a 5 minute period where they asked questions about previous projects.

Had 3 coding interviews. Each were with a different person and it went from good cop to bad cop to worse cop. I can't tell if they were briefed to be increasingly difficult and more cold but the interviews felt more intense as it went on.
