Initially, I sent in a resume and cover letter and was contacted three weeks later with a "writing test"-- they went me some Medicare data and had me answer a few questions about it (this was actually very time consuming). After I sent this in, about a week later I was contacted for a phone interview. I interviewed with someone who had a PhD in Epidemiology; he was very friendly and the interview was pretty standard, asked about my interests and experience (definitely prepare to answer in-depth questions about your research experience including technical details, I wasn't that prepared for this). A few days later they emailed me and set up an in-person interview. The in-person interview was a 4-hour process including an IQ/basic statistics test (1 hour), and 4 one-on-one interviews with different analysts. The in-person interview questions were pretty standard and a little repetitive. I was a little nervous but thought the interview went well overall; but I was emailed about a week later and was not offered a position. The office in Burlingame was a bit unprofessional, but I actually appreciated this because the environment is casual but they get a lot of good work done.
