The process took 2+ months. I interviewed at Google in May 2011
Interview
Two or three phone screens with recruiters. A 30 minute interview with another APM. Then flew out to HQ, from VA, for the on-site interviews. 3 hour long interviews before lunch, lunch interview and 3 varied length interviews after lunch. Was on the campus about 6 hours total. One interview was purely technical, the others were focused on strategy and creative thinking/problem solving.
I applied online. The process took 2 days. I interviewed at Google (Dublin, Dublin) in Jun 2011
Interview
Applied online and within a few days was contacted to have a phone interview. The phone interview lasted 45 minutes - and consisted of questions as: 1) What's your favorite Google Product, how would you improve it. 2) How would you launch YouTube in Turkey, etc.
Then went in for 3 back to back 45 minutes interviews. It was challenging but my interviewers were nice and I enjoyed the conversations. I found that they often repeated questions but were most interested in ways in my ideas for reinventing products and being innovative. In the end, I did not get the job because I didn't have enough experience in marketing to deliver communications across the EMEA (my background is search marketing on the agency side). I would definitely consider applying again.
I applied through college or university. The process took 4 weeks. I interviewed at Google in Feb 2010
