Google Intern interview questions

I applied online and the process took 4 weeks - interviewed at Google in October 2013. Interview Details – I submitted my resume online on their website. A recruiter contacted me within 2 weeks. Interview times are very flexible. Gave me a whole month to pick dates from. I had two phone interviews (45 minutes each) back to back. Interview Question – This was my first technical interview, so I was very unprepared. I will say prepare well. The first interview was not really hard, and the interview help you a lot through the process. Think loud while you are coding (on Google Doc), interviewer will help you, and it allows him to analyze your problem solving skills. It consisted of some String related questions, their efficiencies and way to improve your code. The second interview was meant to be hard (as the interviewer himself mentioned. It was supposed to check your limit. I will not disclose the questions, as I respect their policy. But know you Data Structures well! Like really well. And also efficiency of algorithms.
