Bridgewater Associates IT interview questions

Had a phone interview with a group of people at one time. Phone interview came after Bridgewater sent me a sample project and my job was to perform a code review and evaluate on the developer's solution. The phone interview was not my best experience. First, I could barely hear/understand the interviewers due to the speaker clarity and volume. Second, they were, I felt, one of most 'dry' people' I've ever come across during an interview. This is a downside of phone interviews, you can't see their faces or reaction. Overall, the questions during the phone interview was not tough except that because of their 'cut throat' mentally, they were looking for someone who possess the same ideals and be able to carry on their 'culture' at work. Not a place for me.
