I got to the onsite, day-long, interview stage at Google (about a year ago). It's been awhile, but I do remember they asked some VERY real world questions, ranging from lists related traversal questions, to "how would you implement xyz." Some running times questions, etc. The questions were challenging, but do-able, I suppose. My biggest issue was not so much with the questions, but rather with 1 or 2 of the interviewers who felt it was more of a pissing competition, always trying to undermine the answer. The rest of the people were just phenomenal -- super professional and a pleasure to talk with. In retrospect, it was the younger interviewers who were "problematic." I suppose it has to do with insecurity (I later found out that they weren't at Google for that long, nor were they such hotshots). Lastly, I believe that none of the interviewers asked for any particular coursework or GPA, but the internal Google recruiter asked for either a transcript or flat out GPA, to send to the committee (who reads the interviewers' comments and makes a decision whether to continue further with the interviewee, or not).
