I applied online. The process took 2 weeks. I interviewed at Google in Nov 2013
Interview
I had two back-to-back hour interviews on Google Hangouts. The questions were very fair and straightforward. They asked vocabulary questions about OOP, a design question about a data structure, and a coding exercise. The second interviewer asked me about what I did over the summer and then proceeded to give me a few coding exercises.

Question 1
None of the questions were difficult or unexpected.
I applied through an employee referral. The process took 5 weeks. I interviewed at Google (Mountain View, CA) in Oct 2013
Interview
Two Google+ Hangout technical interviews and most of the questions are fairly easy. Failed to answer one of them but the others went quite smoothly. You can just give a simple answer at the beginning and optimize it step by step after that. Nice interviewers. Results come out the next day(which is surprisingly fast).
I applied through a recruiter. The process took 4 weeks. I interviewed at Google in Apr 2013
Interview
I applied to the Freshman Engineering Practicum through a recruiter. The process went smoothly, and the interview was honestly fairly easy (I just simply had not studied at all for it at). The first question was a code reading question, which was straightforward. The second question was an easy string-related question, but I botched it and I knew I wouldn't get the position.
