Google Software Engineer interview questions

The usual staff. 1 phone call from a recruiter, talked about details about me and about the role. 1 technical interview via Skype. asked me some array algorithm questions Another technical interview via Skye, asked tree questions I am not from the states that's why I had two Skype calls

I applied to Google software engineer intern. I asked one Google employee to refer me. After only one day, I was contacted by a Google recruiter. She scheduled an phone interview for me at a day three weeks later. In my interview, there were two rounds, with the first one from 2pm to 3pm, and the second one from 3pm to 4pm (CST). The interview questions are not hard. They are basic string problems. But I didn't answer them well.
