I interviewed at Cornerstone Research (Washington, DC)
Interview
First round 2 cases: Only cases questions.
Final round is onsite with 4 cases: They seem only care about cases, others are just fairly easy small talk. One securities, one valuation
I interviewed at Cornerstone Research (New York, NY)
Interview
Everyone was welcoming and the cases were interesting. The interviewers seem to be interested in seeing how you think as opposed to looking for a particular answer like you might find in a management consulting interview or a finance interview.
I interviewed at Cornerstone Research (Boston, MA)
Interview
First round was on Zoom with mainly case questions, and the second round was a super-day in person with multiple interviews, a mix of behavioral questions and case questions, felt very fast-paced
