I applied through university. The process took 4 weeks. I interviewed at Google in Mar 2012
Interview
Two phone interviews with one UX researcher and manager, most are technical questions about the UX research methods, and the reason for choosing Google
I had 3 rounds total. 1st round was with HR, with the remaining rounds being with the Head of Product and the tech teams. The last round was the hardest, as I had to do a portfolio review
I applied through a recruiter. I interviewed at Google (Bengaluru)
Interview
3 rounds of tech discussion which I cleared with a positive feedback but suddenly recruiter disappeared and when I reached out for further rounds she mentioned that they have got a internal candidate for this position. Never thought Google will be such an unprofessional organisation.
I didn't make it to the interview part of the process. I highly recommend knowing someone or going through an actual recruiter if you'd like a job at Google. Cold applying online is harder to to secure a job.
