Pros
The benefits and work/life balance. Management is very supportive of work/life balance including telecommuting, occasional work from home, varied schedule, work in an alternate location, etc. Senior Management is very strong, as evidenced by Prudential's journey through the 2008 financial crisis.
Cons
Quick to hire and quick to fire. Prudential is very overfunded in their pension, so they are not hesitant to do lay offs and pay out severance. Most of the time, this occurs because you happen to be in the wrong business unit, or organization. Or.... your work is outsourced. What they don't do, is try to get you placed in anticipation of a lay off. Recently over 100 were laid off, yet there were over 600 jobs advertised internally. This is clearly an opportunity for HR.
