A friend recommended I check Bridgewater out. I met the head recruiter at a recruiting fair, and she was very cool and very nice. I sent in an application online, and got a first round interview. It was a discussion with about 5 other applicants and 3 interviewers sitting around a table. Each of us interviewing was instructed to bring an interesting, open-ended discussion question roughly along the lines of their example question, "If you could make everyone immortal, would you?" It was supposed to be thought-provoking and discussion-provoking. They were interested in seeing how we reasoned and how we thought through interesting questions and problems. I was called the same night and told that I was invited to second-round interviews the next day. I had two second-round interviews, one that was very similar to the first-round (with other applicants), and one that was a behavioral-fit interview.
