I met this company through an campus job fair. They interviewed me for about 1 hour, mainly asked my programming skills and experiences.  Then they sent me an online test link, which like others said, 25 multiple selection questions. I think this is very difficult, and I didn't finished all of them. After that, there was a programming test, that I was required to write a program within 6 hours (at most, the sooner the better). I think it's possible to finish it in 3 hours if you're skilled. Then I got the on-site interview. They offered me with an amazing trip in Santa Barbara! Comfortable hotel, nice beach, friendly host, etc. I felt that they were trying to make you feel well to live in Santa Barbara and work there. I was required to finish a program and make sure it's bug free within 4.5 hours. And also had two interviews on the next day. One with an engineer to talk about the test and programming experiences, the other one is with the head.

There was a quick 20-question quiz followed by an in-person non-technical interview. They simply asked about things on my resume. After this, they offered me an in person tour of the campus in Santa Barbara, but I rejected.
