I applied through a recruiter. The process took 2 months. I interviewed at Bridgewater Associates (Westport, CT) in Jun 2015
Interview
There was an initial interview with an outside recruiter, followed by a battery of assessments (e.g. personality tests) an interview with hiring manager and then a day of interviews with multiple team members. The focus of the day of interviews was to ensure that you understood the culture you would be getting into.
Interview questions [1]
Question 1
These were standard behavioral questions with the additional layer of scrutiny in the form of the classic "5 whys".
