Pros: Decent development processes and tooling. Interesting product technology stack. Public brand name recognition and growing user base.

Cons: Bad managers are everywhere in the company. Don't expect career advancement even after years of project work. Do not assume your management chain will protect you; usually the opposite. There is blatant favoritism in the handing out of new project opportunities, regardless of your interests and/or qualifications.
