I used a headhunter to get a foot in the door. After a pre-screen including several personality tests I had a 30 minute phone interview probing my background. While they emphasized no prior experience was required, they wanted to make sure I had demonstrated the appropriate interest in trading and finance before. It took over a month before they could schedule me for an interview. They provide a lot of resources online, including Ray Dalio's 'Principles', you will want to read these and really figure out if the culture is attractive to you or not. The interview process lasted from 8 to 3, and they will cut it off at any time if you're not what they're looking for, they are frank about that. I won't reveal the details of the interviews but I think being personable, energetic, smart, and applying parts of the principles where appropriate go a long way. Receiving feedback on an offer took about 10 days, there were a few delays outside of either parties control.

A great interview process that was accelerated due to an outstanding offer deadline. The culture is intense and direct, however, I got the sense that Bridgewater is a great place to work. A little different than the average prop-trading interview. It focused more on execution, process evaluation/understanding, and culture fit.
