Google Software Developer interview questions

I received an email from a Google recruiter who located me on LinkedIn, inviting me to interview. I replied saying I was interested and , I had a phone call a couple of days after, with the recruiter where he explained the process to me; Essentially, it was gonna be a 45 minutes technical phone interview followed by an all-day on-site interview. I was also offered a choice of many locations, as Google seems to be hiring a lot in all their offices. A week later, the phone interview took place. The interviewer introduced himself and we had a little chat about the way the interview would be conducted. I was offered a wide choice for the language I would code my solutions in even though the recruiter had only mentioned Python and C++. And then followed the questions. After it was done, I had the opportunity to ask a few questions myself about the position and life at Google. I was then told that the initial recruiter would contact me again after the hiring committee had made its decision about taking whether to take me to the next stage.

The whole interview process was comprised of two phone interviews, and on-site interview. The first phone interview was from an HR, and the second was a technical interview in which I was asked several basic CS problems but no algorithm development or online coding. After that I was invited to fly to Santa Monica, CA for in-person interview. The interview insisted of 5 round of interviews. The content included algorithm, system design, and so on. I though I was doing fine, but after one week, I got a call from the HR told me that I was not accepted due to lacking of working experience. However, the overall process was smooth, the interviewers were nice and friendly. The questions are not really so hard to answer.
