Pros
No shortage of interesting work, problems, or people. Challenging - you'll learn something meaningful every day. Great focus on strong values (merit, creative problem-solving, results, and people). Real atmosphere with real people. For the bold, few barriers to making things occur. A lot of momentum around people making change if they drive it and that being welcomed. While not as consistent (by department) as desired, extremely competitive compensation with great equity and benefits available. Allows one to thrive in LA.
Cons
Company growth outpaces learning regularly - easy to find yourself in the weeds only months after getting a handle on something. Mentorship culture still lacking as a result. "Alpha wolf" pressure can unintentionally make it feel unsafe to be weak or to fail unless you have context with a number of layers of management (to be clear, it's OK to mess up or have weakness, but the environment can make that feel dangerous due to high-performance teams). Resource management is extra difficult, even by other game development standards. As team resource funding (enough engineers/artists/designers/etc) has been blazed by growing scope and size, some teams well-funded, while others scrape hard - even important teams.
