Vantaggi
This is a big company with many legacy companies and platforms under its brand. It's easy to have a good experience, and it's easy to be over worked, under paid, and miserable. I was at TriZetto long enough to experience good leadership, career growth, poor leadership and career stagnation. If you have a well connected manager who is in the good graces of the leadership (Jude + CTS), you and your team will do well. If you (or your management) is in the crosshairs, your boss will be miserable and constantly taken to task, and that will have a downstream impact on you.
Svantaggi
Much of mid/senior (VP/SVP) leadership is a textbook case of the Peter Principle. Very expert but narrow understanding of the market, little/no strong management or mentoring capacity. Some verticals have leadership that is a fraternity culture on a good day. Others are professional slide jockeys and have not brought a dime into the company while creating significant distraction. Work/life balance is terrible. However, comp is decent in many areas. Negotiate a high starting salary- they can afford it and you'll never get it as a raise. I left because I had a bruise from beating my head against a brick wall.
