Pros
Highly intelligent, experienced professionals at the "production" level. People that, if you left out all the peripherals (culture, management, pay, etc.) you would want to work with simply because they know their disciplines. Decent pay for my area.
Cons
Bureaucracy rules, productivity drools. While I ran into the occasional manager who looked out for their people, maybe 10% of their "leadership" is comprised of actual leaders. Despite multiple employee surveys that showed low morale and an office on the downslide, management simply refused to listen to the suggestions offered by employees. Not interested in exploring or leveraging the latest technology. An obscene amount of money and effort go into marketing "values" and "workplace culture" - to the employees. Snazzy office spaces do not make up for not getting your employees the basic things they need, like safety training, decent equipment, and a way to navigate the incredibly restrictive bureaucrats. When you force employees to put thousands of dollars on their credit card for remote trips (no such thing as company cards here) and then delay payment, don't be surprised when they get upset...
