I was initially contacted on LinkedIn by one of their recruiters. The first was a phone screen, followed by 2 technical 30-35 minute long interviews. The process seemed very rushed; I often got notified I "passed" each round of interview (3 phone + in site) within hours of actually interviewing. It was kinda suspicious to me to be totally honest. After the 3rd phone interview I was invited to Los Altos. I went through their Orbitz site and booked my own flight and 1 night hotel stay which was more convenient than them asking you a general time range and doing everything themselves. In general I had a pleasant time there (5 hours), the people are pretty friendly but the 2 people in Austin I had video interviews with were a bit irritable and seemed ticked off at something the whole interview. There also was no consistency in the interviews, the interviewers each just asked it seemed whatever whimsical question they wanted, some personality some technical. The interviews really try to see who will best fit into their corporate culture. I was very friendly the whole process and answered most everything but still didn't get an offer. At the same time, I love technology but I don't "eat, sleep, and breathe" it as I have many hobbies (outdoors, automotive, etc.) I guess I just wasn't the proper fit for them and that's fine.
