Pros
Challenging environment. Awesome company to work for early in your career to use as leverage for the next company. If you are an engineer or PE you will be treated above all other degrees from the time you interview.
Cons
Very thick glass ceiling for women or non-PE or PG's. Huge boys club even when you are asked to be an exclusive 'direct owner'. The only people promoted past PM level are the men or very few women who are the elite in the companies KLF aquires. The upper management does not fire poor managers regardless of mass exodus of junior staff giving scathing exit interviews. They turn blind eyes to blatant discrimination. Oh and don't plan on having kids and choosing to work 40 hours because you will be discussed behind closed doors as not being a good employee regardless of the years of 60 hour weeks. Constant reorganization and $ being spent to do so could be used in much better ways, like salaries.
