Here is one that came this morning. Citadel pays as well as any firm on the planet, but they work you to the bone and the atmosphere is very intense. Some people thrive on that, and even if they don't, few programmers turn down $300k/Year.
my sources tell me they had their worst day ever on 8/10. But they were still up on the year as recently as two weeks ago so I seriously doubt they blew out. I know the head trader of their hedge fund (separate capital pool from the main group) left a couple of weeks ago. Maybe the rumor was something to do with that? Just about everyone in the quant space is having a rough time.
