Pros
Hot technology - or at least it was till ~ 2 years back. Big players seem to be moving in the market now and it is not clear whether VMW has managed to keep lead. Buzz in the area.
Cons
Internal processes non-existent - company grew too rapidly in last 3 years for its own good. Too many top management changes in last few months - as an ex: 6 CIOs in ~ 3 years. Too much arbitrary decision making, lack of transparency, mutual back scratching at the highest levels. Lack of focus on key non-product areas like customer satisfaction, internal business processes, IT applications. Poor flow of information - downwards or upwards - for a company of this size. Amazing focus on empire building rather than organization building (again gven the size of the company, it is dis-proportionately large). Lack of accountability ramapnt in the whole organization - senior 'powerful' people have lot of visibility and power but it seems they are not held accountable when things go wrong - again and again.
