Pros
At Pru, the compensation and benefits package are very competitive. On a periodic basis, salaries are adjusted to be competitive with the salaries within the same industry. The benefits package includes comprehensive health coverage, tuition reimbursement, 401k match, a small pension fund, and a discount on company stock. Opportunities for advancement are also there for the people who wish to pursue them. There is a great internal job posting system to explore the wide array of careers available in the company. In addition, the company promotes work/life balance. The hours, at least in my position, are very manageable. This is a pretty uncommon find in the financial industry.
Cons
If you don't like the idea of working for a large firm, where your function is very specific, than Pru is not for you. However, this is usually the way it is for all large firms. In my position, I have the opportunity to work with other groups, but not to the extent I'd like. There is sometimes a disconnect when interacting with other groups, since the terms and concepts used can be different. I also don't get exposed to what other groups do as much as I'd like. This may just be due to the group I'm in, so I can't speak for the whole company.
