* Very nepotistic, although this may not be different from any other company. Future upper management selected very early on in their careers; they will get mentorship opportunities that you will not.
* Related to the above point, temper your career expectations. This is a good place to stay for many years while bringing in a consistent, solid paycheck. The level of nepotism and foreign delegates who come to the US and occupy management spots mean you are not likely to see much upward growth, as others who have been hand picked as "future leaders" will occupy those spots. Sometimes, they won't even interview for them.
* Generally does not (monetarily) value technical expertise. You will not be "highly" compensated unless you are a manager type and every young engineer (especially PDPs) wants to be an SVP one day, so good luck
* Early career engineers generally pressured to stay technical by the very people who did not stay technical for obvious reasons (compensation, upward opportunities), and it will be at the young professional's expense but the managers' benefit
