Great people, Flexible work environment. Free Lunch. Get exposed to a lot of work which is ok if you are early in your career, but not good for mid-level or senior level career workers.
Cons
Terrible office location. No investment or freedom in R&D to do interesting work. Most projects are "me too" or small changes. Sales drives product goals, so big changes to product are discouraged. No accountability on management for company failures, instead they layoff lower-level employees.
