Pros
Salary (large reason I didn't quit) A lot of good people and engineers (main reason I didn't quit) Benefits are standard for large companies.
Cons
Upper management cannot make smart decisions to save their lives or the company. The work-life balance is poor. You can't expect a raise from a bankrupt company; you can expect people getting laid off and frozen salaries while certain people receive absurd bonuses. Director-level and up are paid far to much for what they bring to the table. The engineers who actually do the work and are constantly trying to fix others' mistakes are not valued. I tried to choose the career path I wanted at all of my performance reviews, and my manager (no matter who it was, and they rotated a lot) would always want me to stay where I was because there was never enough people do the work. Could never advance. No one really cared about me or my career.
