I applied through university. The process took 4 weeks. I interviewed at Google (Bengaluru) in Oct 2012
Interview
1st round was an aptitude test. The results of the aptitude test were announced after about a month. The next round was a personal interview. We were told that there will be around 3 rounds of personal interview rounds after which, if selected, they will get back to us after our CV was reviewed by Google staffs globally.
