Pros
ACI is well positioned and widely recognized within its industry and is in possession of a good cash flow engine: the POS (Point of Sale) terminal network. Prior to 2008, ACI had had a good record of employee retention and was growing rapidly, albeit mostly by acquisition. The benefits package is comprehensive - not outstanding but at least competitive with what you'd find elsewhere. Most ACI products were well established and actually in use by real paying customers with real money on the line, which can be a real upside for those who tend to sell their souls to projects that never see the light of day.
Cons
Rapid expansion means there is no corporate culture to speak of. Once acquired, new divisions may be left to rot while senior management pursues its expansionist agenda. In the trenches, focus is on cost containment, not on achievement or excellence. Ironically, the bureaucratic policies which stifle innovation actually wind up making everything take longer and cost more. The twin polices of growth though acquisition and cost containment mean that career advancement opportunities are limited, unless you are an immigrant from India and favored to supervise all the development work that all got moved overseas. All these problems became even more exaggerated by the 2008 financial meltdown, of course.
