Avantages
Large company with some potential for individual promotion depending on the group you work with. Big data and health care is hot right now. Depending on your manager, employees may have the ability to work from home more than one day per week.
Inconvénients
Communication from upper level management is poor and almost non-existent. Most of your day is spent watching your butt and answering emails. Acquisitions made over the past few years have allowed the company to obtain new data sources, but poor antiquated, proprietary technology and a lack of process and planning has slowed development and innovation down to a snail's pace. I can only speak to the King of Prussia office, but employees are resigning in droves and those who remain, seem miserable, disengaged and nervous. Architects are designing the solutions and the product / business side of the house is weak, disengaged and offers little to no strategy or direction. Most of the 'software' being developed is really just glorified web forms and looks like it was developed in the year 1995. The health benefits are horrific and many managers are overpaid, under qualified and lack integrity. The company does not properly apply agile principles to development. User research is something this group doesn't understand. Customers are not engaged when they should be and are often lied to by sales and project managers. There is a lack of cohesive and concrete go to market strategy. This company is a glorified data re-seller and not best in class in any other category. My recommendation is stay away unless you want to stagnate your career.
