Compensation and benefits, which is where it ends
Cons
Now, before anyone assumes that long hours and unpleasant people are part of the Wall Street culture, note that I've worked for a large Wall Street firm before BLK. At the other firm, management worked hard to make sure people were working human hours, and people were genuinely nice. On my team at BLK, if you came in after 8, or left before 7:30 p.m. people would talk about you behind your back. I had ideas for reducing analyst hours but no one wanted to hear about it... it was as if upper management liked seeing their analysts work 13 hour days. They also only seem to hire people with A+ personalities... not good because people are out for themselves and don't know how to work as a team. They also use BLK as a stepping stone and don't genuinely care about their jobs - they put in lots of hours for "face time" and to get a free dinner but in reality the job can get done much quicker.
