The process was quite straight forward. I was contacted via email from a recruiter inviting me to make a 2 hours exercise from my home. I did the following weekend and I did reasonable ok. Even, I was not aware about the platform used and this was a real impact factor in my overall performance. Anyway, even I was assuming that it was the end, the recruiter called me the monday after explain me that i did ok but they wanted to conduct a phone interview. I did and I solved the questions (relatively easy) by phone (mostly coding interview). Then, I was invited to Seattle the week after. I meet with 7 engineers, senior software managers and the hiring manager. Some of the interviews were hard but in average I feel that the interviews were ok. It was a great experience, I met great and smart people and had great technical discussions. That afternoon, they indicated me that I had an offer, so the end of the tale was great :-).
