After 1st round of screening through phone and 2nd round of interviewing with a potential manager, I was brought to final round of interviews at the actual NYC office. The final face-to-face interview consisted of meeting 4 senior level Googlers from different departments. Two were through webcam conferences and two I met in person. Recruiter was very nice and walked me through the process diligently. One thing I didn't like about the process was that although the recruiter told me that Google was trying to avoid those off-the-wall difficult crazy interviewing questions, I was not prepared for some case interview and estimation type questions that I had not prepared before. They were keen to try to find analytical qualities in me and since I did badly on those case-type questions, I feel like I was not able to show those qualities adequately. If I knew they would ask market-size questions or case questions, I definitely would have read a book or two beforehand to prepare more. The decision process after the final interview actually took 1~2 weeks which sounds shorter than it seemed at the time.
