Google Software Engineer Internship interview questions

I was offered an internship after only one technical coding phone interview. The interview was about 1 hour. We a started with some friendly get-to-know-you chit chat before getting into the coding. The coding problem started very easy but there were a few levels of extension that made the problem more challenging. After the main coding part of the interview we had some time left and the interviewer quizzed me on my knowledge of hash tables. Interviewer was very friendly and it was a great experience.
