Pros
Salary, benefits (although theses are eroded every couple years). Like any company, if you manage to find your technical niche or a good team, things can be pretty awesome. Great for folk in areas that don't feel compelled to innovate through bureaucracy or just want a 9 to 5. If you see yourself as an "idea person" that doesn't want to dig into the details, you'll fit in great. Decent starting out point for a career after which you'll get bored in 3 to 5 years. Many opportunities to advance given high attrition.
Cons
A tall and inverted management pyramid. Poor communication at all levels, information withholding. Competition between NG campuses and even between buildings and groups on the same campus. Not a good long term place for technically minded or younger/mid level engineers. High attrition with little loyalty/pride for current employees. The Dead Sea Effect (innovative folk evaporate, raising salinity, killing life) is in full effect. Lack of REAL technical expertise in key engineering areas leaves "leaders" who are glorified accountants or wannabe YouTube vloggers or well practiced sycophants. It's so bad in certain areas, they can't recognize/attract good hires because they don't have anyone truly versed in the state of the art to accurately gauge candidates' expertise. You will be treated as a number, especially every couple years when it's time to cut employee benefits and buy back more stocks/issue dividends. Even the laudable goals like "Diversity" are executed by management in a misguided, very prescriptive way that no one truly buys into, but games to increase their managers' numbers. The culture is not inclusive no matter how many metrics the CEO quotes in his video proclamations: it's an echo chamber. As executed, even as a "person of color" I felt dirty by it. Managers with strong preexisting, but subconscious racial biases subtly advance "their own" to counteract the wave of "diversity hires" they think others are forced to bring in. The culture of "metrics gaming" is so strong, I wouldn't put it past people to submit fake Glassdoor reviews to help out their "Engagement Metrics".
