Pros
Flexible and reasonable management culture with respect to work/life balance. There are some great and interesting positions available if you are not a fund accountant (PDP, research or trading positions in SSGM, and portfolio management positions in SSGA). If you're willing to look hard, there are plenty of great people as well, many who opted to exchange a better lifestyle for less pay. I advise joining their many groups and social events to meet them.
Cons
Not a particularly prestigious place to work, which makes it hard to move to more elite institutions later. Compensation is average to poor. Some people are great, others...not so much (as in, not particularly intellectual or thoughtful, though to be fair, some of their jobs don't require them to be!).
