Google Software Engineer - Internship interview questions

I got an email from my recruiter, scheduled the technical interviews in the next two weeks, and had two interviews over the course of three days. The second interview was much more difficult than the first, but both were pretty difficult.

Two interviews over the phone after having a brief talk with the recruiter. The most annoying part is the host matching that can take a lot of time, fortunately it was fast this time but for other interns it took a lot of time.
