Was contacted by the HR with reference to my resume on a job portal. It was followed by 2 telephonic interviews with SDMs. A few days later got an invitation to come to Seattle to have interviews onsite. Total 7 interviews starting with a Senior SDE and going up to the Director of the hiring group. I'm not sure if there was a bar raiser - but I assume so, since there was a Director from another group making the final interview. Interviewers were polite and very engaging. Overall, the hiring process was very smooth and well coordinated
