Fairly long process, received a message from a recruiter, recruiter then did his/her thing and got me an interview at BW a few weeks later after I took an online personality test. Interview at Bridgewater lasted all day and was fairly easy going. Discussion/Case Study/Regular interview. Basically there is no prep you can do - if you are a good fit you'll make it. If not, you'll know fairly quickly.

The process is lengthy, designed to throw candidates off and involves spending hours talking personality tests, reviewing materials and watching videos. There was a "life interview", a group interview, a mock client interview, and Q&A.
