Initial phone screening by HR, then phone screening by hiring manager. Then 3 in-person interviews at the job site (included hiring manager). Then 2 additional phone interviews (they wanted to move fast because job req was going to be closed if they didn't hire someone). Nice office in San Francisco on Market St near Ferry Building. While I was waiting in lobby / coffee area, I saw a couple informal meetings taking place on the fly, so seemed like an interactive / energetic atmosphere - a young / hip type culture that you'd expect for San Francisco.
