Very nice people throughout -- very focused on balance of quantitative and qualitative strengths; one alone will not get you the position. As is true with most firms of this caliber, people are impressively intelligent, interesting, passionate, and driven, while managing to remain bizarrely (seemingly) down to earth. Very few are larger than life, but everyone is remarkable in their own right. Did not secure the position, but left with a positive impression of the company and its people.
