I applied through a recruiter. The process took 3 weeks. I interviewed at Bridgewater Associates
Interview
I had 2 phone interviews, one with the HR recruiter and then another with the hiring manager, and then flew in for an on-site interview. The on-site interview lasted a whole day (approximately 9:30am-5pm) and included 5 sessions with multiple people from different groups (who would be my managers/piers/employees) as well as sessions for listening to or watching recordings of meetings & sessions held at the company to get a better feel of the culture which is the most important thing at Bridgewater.
I also had to complete a couple of personality tests prior to flying in for the on-site interview.
Interview questions [1]
Question 1
I was pretty well prepared so nothing was really unexpected. You should be prepared for some questions related to your role but most of it will be around the culture to test your ability to handle criticism, feedback, disagreements, etc.
