Vantaggi
Looks good on a resume but do not look at this company for any long term employment. If you work in ales, you can be in a position to earn a lot of money. If you are in the technical ranks, you will have exposure to some interesting technologies. If you are interested in management, you could make a good career at IBM if you can learn to manage upward, never make waves, never challenge directives issued by managers above you, always tell managers above you that they are doing a teriffic job. If you are in the technical area, you can tell your manager you are accomplishing goals that you are not reaching as they do not seem to check unless you do something that may make them look bad to their manager.
Svantaggi
Technical people are treated as if they are a dime a dozen while managers are thought of as non-replaceable regrdless of whether they are competent or not. The current philosophy within the company is to manage upward. Do not challenge directives regardless of how dumb they might be. Do not make any kind of waves. As managers, they surround themselves with people that will only agree with their positions and ideas. There is no medical coverage for any family member unless that family member existed before the company dropped covering any new family members (wife, huband, child). The retirement plan is non-existent unless you qualify for the previous retirement plan (and few do). The technical people are considered a necessary evil and are encouraged to look for jobs else where after a few years so that they do not have to pay technical people what they are worth. The lower managers are poorly trained in management and not involved in what their employees are doing. Most are looking out only for their careers and could care less about their employees or the products being prodiced.
