Pros
Exposure to end to end, not a cog in the machine, your ideas matter regardless of your level, you get ownership over your work, travel, international exposure, better benefits than any US based company i've ever seen, amazing passionate people, less conservative politics - ideas matter first, cool fun product, active lifestyle, work life balance, growth opportunities, fun environment, laid back office attire, huge windows and lots of space when you work (versus being crammed in a line or distracting open floor plans, they care about growing you, and they have best culture and values - I often wish i never left.
Cons
less pay that competition, pressure to perform higher than the competitions, less resources and impact if not at HQ, singular mindset / tunnel vision for career movement
