Google Intern interview questions

I had 3 technical phone interviews. Each interview was 45 minutes long. A few days after the interviews I received an email where the recruiter said that we can move to the next phase. The next phase was about waiting: a team had to choose me. Fortunately I didn't have to wait long. The 4th interview was with the host, it was approx 30 minutes long. The interview was about the project they are working on. I didn't get any technical questions.
