I applied through college or university. The process took 5 weeks. I interviewed at Cornerstone Research (Menlo Park, CA) in Oct 2011
Interview
The case interview process and the interviewer experience is wonderful. I really enjoyed the conversation I had with my interviewer and thought the case was challenging, but interesting. I was always able to ask questions and get guidance as I needed it. They do a great job of making sure that your questions are answered. The office-preference question comes in the first round, so have an answer for that early - be honest and direct about it, but say where you're open to working after your top choice.

First round is 2 back to back interview rounds with two different Cornerstone analysts/associates in the office you indicated. Pretty standard Econ consulting cases, not too difficult. Cases are adapted from Also some basic behavioral questions about yourself, interest in the field, research experience, etc.
