Went at their SF Office and got scheduled interview with 6 different people. I was ask to bring my own laptop for the coding exercise. Other interviews I had schedule where with the head of HR, CTO on leadership skills, Lead engineer on Design/Architecture, another leadership interview and interview with Product. When I arrived, reception desk did not have my name at the entrance, so I had to call someone to get me in. First interviewer was 10mins late and we skipped intro so got straight to the coding. Question was fairly easy and was able to code it up, run couple of test cases and make some improvements with execution complexity. This followed by interview lunch with HR person where we discussed my previous experience working with HR. Next was leadership conversation with CTO. Pretty classic questions on management style, how/when to promote/fire someone, consensus reaching and working with product. Design interview was about SOA and how to design the payments system. Interviewer was happy with the solution and we went on an deeply discussed current architecture that they have. After getting back from the break, the room I had was occupied and HR contact told me that we should not continue the rest of the interviews. Got impression that CTO does not care about consensus reaching at all.

First it was recruiter screen over phone followed by round 1 which had 2 interviews. First it was 60 min system design followed by 45 min team hiring/management interview. It seemed straightforward process.
