Vantaggi
Salary and benefits. In the past they empowered the employee to do great things, now not at all. The technology and availability of "state of the art" equipment is awesome. The labs and expertise of co-workers is also great.
Svantaggi
It WAS the best employer to work for in the 90's but now is far too focused on profit and micro-management. Too many layers of managers managing time and metrics. Everything is far too focused on managing peoples efficiencies so most people are stifled and the atmosphere isn't like it was in the 90's. I'm not saying that they can go back, I'm just saying that the focus WAS on technology, coolness and $$. Now is is squarly just focused on maximizing profit. I left after 9 years of employment to another smaller "start up" type company.
