The process took 4 weeks. I interviewed at Google (Mountain View, CA) in Dec 2009
Interview
Asked many behaivoral questions around what i woudl do in certain situations with regard to risk. Most of the people were very nice until I got a girl who looked less happy and was simply reading off her interview sheet. Other than that, most of my interviewers were very at ease and nice to me. I was asked to wait for about an hour for a moer senior manager to come out and interview me.
