Interview questions [1]
Question 1
Asked about evaluating strengths and weaknesses of various modeling techniques
I interviewed at Cornerstone Research (Menlo Park, CA)
Interview
The interview was split between behavioral (20 mins) and a economic case. This is the first round, once you do this you will have more case rounds. The superday is 4 back to back cases (40 mins each) in person.
The interview process was succinct, but it was difficult. Depending on the office, they take only a few candidates, so it is extremely competitive, so bring your A-game; you will need to be near-perfect.
