Vantaggi
Some really good people on the various teams and decent camaraderie which is largely brought about because of the shared hardship of having to work in such a sorry company. Executive leadership sees employees as a disposable asset and no job is safe from being sent offshore unless it absolutely must be client-facing.
Svantaggi
No significant pay increases to speak of for the last five years, although they will sometimes counter-offer if they are about to lose a critical person. Bonuses are also a myth that haven't been seen in years except for a fractional payout in 2011. It may be in your offer, but don't expect to ever see a dime of it unless you are related to the CEO. Get it in your base pay or don;t get it at all. Benefits are very expensive. 401(k) has no match and if you are a high-comp employee, expect to be excluded after your first year because they never pass non-discrimination testing on their 401(k) plan.
