It has been an unexpected wellspring of opportunity.
Pros
Life is what you make of it; so is work. I can always say that this is the best place I have ever worked. In IT the Operating Principal to "Be the low-cost provider" seems to lead to a willingness to consider creative solutions and innovations. There have been several "submit an idea" systems and competitions. I participated, and it lead to a presentation to executive management. The opportunities that arose from that are immeasurable. I've spoken with healthcare professionals and have been told that our plan is the best one offered by BCBS to private companies. Several members in mid and top management started at the most basic entry level positions. The culture is supportive of exploring other jobs within the company. There is a tuition reimbursement system, at least one scholarship program, and a full suite of training classes both online and instructor lead. It is a large, stable, and growing company that enjoys the backing of Warren Buffet. I've been fortunate enough to speak with 3 of the top executives in the past year and I can say that every indication is that they are sharp, knowledgeable, and very much engaged in the business. I am humbled by their breadth of knowledge and insights. Many employees hope that their children can work here. I even met my wife here.
Cons
The entry jobs, especially on the business side, can be tough. There's a lot of work and tightly managed schedules. Stick with it, work your way up, and you'll find it keeps getting better. This is not the place for those that don't want to work hard. If "Be the low-cost provider" is improperly administered it could become "penny wise and pound foolish".
