The first phone call was with a recruiter. They liked some work I'd done on an open source project that they use internally. The second phone call was They flew me out to San Francisco. I got to stay for three days. Only one day was spent interviewing. The other two days I visited friends and saw the sights of San Francisco. There were four interviews, but I spent the lunch break talking with some one, I think it was mostly about fit, so I count that as the fifth interview. Overall it was pretty nice experience. The questions were mostly very interesting questions. With some of them it's hard to even know where to start. Even if I didn't get the job, I enjoyed seeing San Francisco. The interviews themselves were very difficult. I really thought that I hadn't done well. I made a lot of coding mistakes, but I got an email two weeks later saying they were interested in hiring me. Yay!

The whole interview was ok but I did sucks. Based on phone, you can choose what ever language you like. It interviewer went directly to the programming part. 2 small coding task asked. Anyway, it's relatively easy to get a interview. But I guess it's not very easy to continue.
