Hiring process took some time with approximately 2 weeks in between each step. First was a phone interview with a member of the department. If you get to the next level, they will schedule an in-person interview at their San Mateo HQ with a panel/group of people in that department. Each interviewer is allotted 30-45 mins each to interview you. One was conversational and the other two were semi-formal but not rigid like other interviews. Applied for this position but ended being considered for another position which was good and bad. I was told I may be considered for another position but did not get into specifics until I received the actual offer. I was given two days to respond to their offer letter, which was rather fast in my opinion.
