Application
I applied through college or university. I interviewed at Cornerstone Research (Washington, DC (US)).
Interview
First round – 2, 40-minute interviews with Analysts involving a very brief behavioral portion (1-2 questions each), then an interviewer-led case with qualitative and quantitative elements, followed by a chance to ask them questions. They were extremely friendly and welcoming, the cases were medium-difficulty, but very doable if you do your research on the company and read through their example cases in various practice areas. I messed up my math on one occasion and asked for help, but the interviewer happily did help me and I still got a final round interview.
The final round was much tougher: 4, 40-minute interviews and a 20-minute Q&A. The interviewers were of differing roles including more higher-ups. Each involved behavioral and case questions, some focusing more on one portion than the other. The cases were similar to the first round, if a bit more challenging, some involving no math and just reasoning with lots of questions about your reasoning. My resume was very very thoroughly verified with me. The Q&A was informal and more for my benefit.
I heard back a week later.
