I was contacted by a Google recruiter by phone. My resume was on file from a previous interview 3 years ago which did not result in an offer. We had a short conversation about what was available at Google and about what my experience was. The questions and information were very high level and it didn't seem like this was even a phone screen of any sort. She then passed me on to the HR person at the NY office. I was told that there would be a phone interview where I would need to be at a computer and would need to be able to code, but since I has already been onsite previously they decided to skip this. I was handed on to yet another person to actually schedule the interview and then back to the HR person. The onsite interview was from 10 to 3 and consisted of 5 interviews and a lunch conversation. Each interview was 45 minutes and they ran pretty much right on schedule. They were difficult, but pretty much what was expected. There almost no discussion of work history or anything other than technical questions. Most of the time was spent at the whiteboard working on and then refining the answer to a question. They mainly focused on data structures and algorithms around them. Things like BST, hash tables, tree traversals. The questions were not standard algorithm questions that you tend to see around, but a bit more involved. They were interested in your speaking about the algorithmic complexity of your solution and how to choose appropriate data structures. Hash vs. BST came up a bit. The coding that had to be done was a bit awkward for a whiteboard. The solutions were not necessarily short. One interview revolved around a higher level system design question that was refined throughout the discussion. There was very little to no time to ask questions or discuss working at google and the inteviewers did not seem interested in selling me on google. The lunch conversation was not an interview and did not contribute towards the assessment. The person I ate with was very nice and seemed honest about the way things are at google. Over 2 weeks after the interview I was contacted with the rejection. Overall the process was smooth and people were helpful and nice. Though I did not find anyone to be particularly interested in selling the company. The interviewers were hard but fair for the most part. One interviewer did not describe the problem particularly well and had me coding a solution to the wrong problem for a while.
