I did not get the offer, but I must say that I was very impressed with the whole process. Bridgewater is such an odd and awesome firm. I applied online, then got a phone interview that was basically screening, and asking a few general technical concepts, I thought I had done quite badly (the interviewer did not sound pleased) but I got to fly to their HQ.. I had about 6 different interviews, first a group interview, discussing and abstract concept on how to develop a project. Then some of the candidates where basically told to go home. Every interview evaluated a different aspect on my character or ability. They were interested in seeing how I thought rather than what I knew. Everyone was very nice, some interviewers asked hard question but it always felt very fair. Furthermore, they were even willing to share feedback about my interview after I was informed that I did not get the position.
