Pros: I was paid very well.

Cons: Had to work very long work hours.

Pros: Some excellent engineers and techs. Having an unlimited budget. No door policy, and you can message or call anyone you want. Access to all parts of the company and the most amazing ideas becoming reality.

Cons: Managers use metrics to show themselves and promote their own careers. They will throw you under the bus in an instant. Keep your opinions to yourself and your friendships elsewhere. It is a very clique culture and you never know who is who. Top level management is amazing, but some of the local managers are basically analysts who self-promote their agenda.

Pros: You will be able to learn more and do more (with direct responsibility) than nearly any other large company. The mission is inspiring and motivating in a way that very few other places can offer.

Cons: Large time commitment for relatively lower pay, because you are effectively paying tuition to learn from smart people. High variability in management, since some are great and some are bad.
