Google Software Engineer Internship interview questions

I applied online and after a month I got a mail for coding interview after I completed the coding assessment within a week I was scheduled for 2 45 minutes technical phone interview.

Standard procedure after applying online. Coding sample (2 in 90 min), then the final round of two phone calls with Google Docs and Google Employee, 45 minutes each. Small surveys and questionnaires regarding logistics but focus primarily on technical aspects of interview.
