From what I've seen in my time on multiple teams here, managers come in from different companies, take over teams, hire their own friends primarily from their previous companies, and then give the promotions to those people in a very short time. You may spend years hearing praise for the work you do, but it's never backed up with promotions. Also, this is not a good place to work if you are at all introverted, value family life more than work life, or prefer to work a normal person's schedule. If you are in a non-technical role, you also have little chance of seeing any kind of career advancement. Large divide in pay between people on the same teams and little transparency into the payment and growth processes.
Additionally, most employees share a highly liberal political stance, which drives the culture in a mostly positive way, but it also requires that everyone agrees with the mindset. Those that have differing values can expect to feel ostracized.
Finally, the treatment of vendors and contractors (including facilities staff, janitors, kitchen staff, security guards, and receptionists, among others) by employees can be staggeringly disappointing, embarrassing, and offensive. There is so much of a sense of entitlement upon employees that many seem to view others as second-class citizens.
