I had abput 12 interviews with people from HR (Recruiters), Team (Sales, Presales, and Managers), Gogliness (People from other departments, positions even offices to see if I would fit at Google) I had two presential visits with 4 interviews the first day and one interview with 4 people the second. I had 7 HangOuts and Phone calls and about 50 emails. The whole process took 5 months I had to prepare a Case to defend it in front of 4 people 2 in the Offices two with HangOut, this was the most tough one, because they thought that someone had helped internally me but that was not true. I had to give 5 contacts for the references I Went to the hiring comitee in California twice, or at least thats what they told me and finally the position dissapeared from Madrid and was moved to Paris.
