Pros
The benefits and perceived respect for IBM in the marketplace.
Cons
Unless you reside in the ivory tower in Armonk, you are just a serial # to this company. Management is a joke. They are not respected, because generally speaking, most of them are incompetent. They rely on their team to make them look good, so when it comes time for recognition, they have no problem accepting it for themselves, rather than passing it on to those who "truly" deserve it. The PBC rating system (yearly review) is a joke, it is a luck of the draw exercise. I have found that in 10 years with the company, it seems we spend more time trying to justify our employment by making sure our powerpoint presentations look pretty and also that the data presented to executives is as "accurate as possible". Employee morale is horrible. It has become a depressing company to work for.
