I submitted my resume through a referral and received a phone call from a recruiter who went over basic details. The recruiter then set up a technical phone screen.
The technical phone screen was mostly about discussing my resume and projects I had worked on, including the process and approach I took in solving problems and the tools I had used. You might have encountered a fun brain-teaser or two.
After the technical phone interview, I was recommended for an onsite interview. The onsite was a full day and very intense, but I enjoyed it quite a bit.
It started with a brief tour of the (very impressive) facilities. Then, I gave a 20-minute presentation about a project I had worked on in front of 7 or 8 people, fielding technical and critical questions throughout. It is expected that you can defend your decisions and analysis.
Afterwards, I had a series of one-on-one interviews (about 6 or 7) which ranged in difficulty. Most interviewers were concerned with my ability to think through a problem and consider details. Typical questions included, "How would you set up a test to evaluate X, Y, Z?"
If you are sharp and can think critically, you will do well. Everyone was very nice; nobody was trying to trick me. They simply asked me to consider challenging problems and walked through various scenarios. It was a tad bit exhausting, but I enjoyed the people I was interviewing with.
