The process took 2 months. I interviewed at Google (Dublin, Dublin) in Jun 2013
Interview
5 phone screens 5 on-site interviews. First screen with HR, asking quick questions (what's the opposite of malloc and so on). Multiple shared documents programming tests in C and Python. On-site: 3 programming, 2 in C, 1 in Python, 1 networks, 1 large systems design. Be sure to prepare for large systems design!
I applied through a recruiter. The process took 8 weeks. I interviewed at Google in Mar 2016
Interview
Contacted by recruiter during senior year of college. Arranged two virtual interviews. The first one led to the second one because the interviewer thought he was interviewing for a Software Engineer position. Both interviewers were simultaneously professional and easy to talk with.
Prepare for your interviews - the questions they ask can very be difficult!
The recruiters I talked with - there were three total - were VERY helpful and professional. They were my biggest advocates.
Except for one incident where one of my interviewers never called me. I emailed my recruiter several times when they my interviewer hadn't called, but didn't get a response. I called, but got a voicemail. Halfway through the interview window I emailed saying that I don't have time to wait any longer and that we should reschedule for later in the day. (I had a class to go to!) When I got out of my class, I had an email from the recruiter that insinuated *I* was the one who missed the phone interview. That really rubbed me the wrong way, but I swallowed my pride and took the next available interview time, which was 2 weeks later. The next interview I had was fine.

Interview
The recruiter was professional and polite, the technical task was interesting. Overall positive experience. You're given time to prepare, and enough information on what to expect and the interview process.
