what specifically about the environment are you worried about? Are u expected to perform? Yes. Politics?Yes , i guess anywhere in a large firm you can't run away from it. Paywise? Policy is to be middle of market so won't be outstandingly stellar compared to other similar compaites.
What kind of negativity? This can be specific to the individual and circumstances, crap manager maybe?
Sounds like u are fresh in the field. Speaking form experience Intel is a good place to at least try out and see if it suits you. If no, u still hv lots of time to jump ship and explore other options. Hey, it works to have Intel on your resume, u know?
