Pros
The work is amazing. The amount of talent here is staggering. They bring in the best artists around the world and every one of them is impossibly nice. There are very few bad eggs and they are routed out quickly. The campus is great, right by a trail for walks. They have a cafe for quick easy food if you're not that picky. There are classes for artists that are very rewarding. The life drawing and sculpture classes are fantastic. They are great with employees who need help or develop issues with hands, etc., providing standing desks and ergonomic help. They have a decent healthcare plan and now provide a basic plan to contractors. Many teams have fun team building events and lunches. Playing games in encouraged if not required, even on teams not working directly with the games. Blizzcon is a ton of fun and one of the highlights of anyone's career. It beats any film premiere. The team is everything. Each team is like working at a different studio. My negative review below ONLY concerns the cinematics department. Other teams seem to have their pipelines working better than ours and even other parts of cinematics seem better than others. Try to find someone working on the team you are interested and ask them what it's like.
Cons
Make no mistake. This is a corporation. That means that no matter how much you love the games, no matter your talent, you are going to work under about 30 leads who have been here since the beginning of time. You will have no say in what you work on or what it looks like. There is little growth career wise and you might not want it. Most senior artists don't make OT which means it might make financial sense to be a regular artist if you are putting in long hours. If you are a real artist and want to make something of your own you might want to look at going to a smaller studio where you can have a bit more say in your art. There are many producers and they believe their job is to crack the whip rather than protect the artist. EA at least had DDs that keep the OT reasonable and the deadlines manageable. If you need any new software it will take months IF you get it. If you want to switch teams here you have to formally apply. You will even have to do a test and you are treated the same as an external person applying. If you leave Blizzard and want to come back you are given no favoritism. They are just as likely to hire someone who's never worked there even if you give them a decade.
