Pros
People who are friendly, willing to share, and hard working. There are more positive people than negative ones. The pay structure, vacation plan, ESPP, and other benifits. Hard work can be rewarded. The work itself is ever changing. There is a great work/life balance.
Cons
A set of people who think they are better then those around them, who play politics, and pass the buck whenever they think blame may come their way. They are usually evident, as others usually avoid them, or the business they are in is suffering. And, second is a set of people who refuse to change. They are stuck in the way things used to be, and don't see that the market has either moved, or that no one ever liked the way it was. Also, Advantest and Verigy have not merged together as smoothly as one would have hoped.
