Pros
I've never worked for a company where the people are so willing to put in the time and effort to make things happen. They are truly the reason why this company is successful. The workforce is quite young, and very engaging and ambitious. Poor saps don't know any better...
Cons
Despite the 50+ VPs, there are only about 5 people that have real decision-making power. They love using the word "entrepreneurial", but it's only a buzzword that's used to recruit people that think they might actually be able to make real, value-driven decisions - it's a total farce though. I report to a VP, but I am constantly providing the same updates and info to the 3 VPs above my boss - and their directives to me often conflict with each other. This company "seems" interested in improving the work/life balance, but this campaign obviously takes a back seat to the pursuit of insane, unsustainable growth. Invenergy is a successful company ONLY because the rank and file do whatever it takes to make it so. I'm amazed at how people consistently put in 60hrs/wk for average industry pay (and it's average only if you max out your bonus). I can't count how many 9pm IMs and phone calls I've had with colleagues just because they happened to be working late along with me. And because everyone is willing to put in such an effort, it has become the expectation if you want a chance at moving up.
