Pros
If competent, lots of responsibility will be afforded to you--good resume builder Usually surrounded by smart people within their respective fields--opportunities to learn a lot Teams, in-general, work hard to get job done
Cons
Mid Managers are often underqualified--little management experience and poor decision making Not a meritocracy, " old, white bureaucrats syndrome", must do your time or politic well... Huge silo effect, engineers and business managers operate in a vacuum Ethics can be gravely questionable Little emphasis on mentoring and coaching entry level employees Must enter with high salary--internal raises are negligible unless you move projects often--restrictions on job changes Less emphasis on quality, just get it done mentality...
