Google Senior Software Developer interview questions

I was approached by a Google recruiter, with whom I had an email exchange, followed by a very pleasant phone conversation, all about my interests and history. I then received a very detailed email with a lot of material for applicants, including videos by interviewers explaining what they are looking for. I later had a technical phone interview, using a Googledoc for collaborative editing. I had to write some code. I was then invited to their Tel Aviv office, for a rather hectic day with 5 interviews, each by one person. There was another person whose sole responsibility was to go to lunch with me. Apparently, if I had had a contact in Google, they would have asked them to accompany me. One of the interviewers asked me rather unfair C++ trivia questions, but all the rest only asked me programming, design, algorithm etc. questions. One interview was conducted entirely in English, even though both I and the interviewer speak fluent Hebrew. I imagine that this was meant to gauge my level of English.

My recruiter called me to have an interview in next week and did not call me back first time. At second time, she said she can arrange an interview in next week, I was so afraid to loose the opportunity and agreed to take it even I did not have enough time to prepare for it. I think google's interview needs intensive preparation.
