Pros
When I joined RealPage, there were opportunities for growth, there was an aggressiveness to competing in the market place, and there was the ability to innovate and make a difference. There are still groups within RealPage that are that way, but they seem to be a dying breed.
Cons
RealPage has moved most of its development to India or the Philippines. They don't really innovate much anymore - they are mostly in maintenance mode. I've heard they are now an Agile shop and certainly engineering in the US has been significantly reorganized, but those I've talked to who still work there say it is window dressing, and nothing has really changed. Often, the people who are really good do not get promoted - they get sidelined. I guess it depends on the division/product.
