Pros
What you've read about Tableau's culture is true. This is the best place I've worked as a marketing person. Is it perfect? No but it's so much better than any other place. People are smart and creative and nice. They work hard and they care. The leaders are open and real. They're transparent. And they are good at marketing in their own right. Plus the product is well-loved by customers. You'll learn a lot here.
Kontras
Growing and scaling pains for sure, some inflicted by new people who don't get it or junior people who haven't seen how bad it can be elsewhere, some from fast growth that's now slowing. As it's grown into a large group, mid-level people are losing some ability to be nimble and make decisions. Pay could be better for sure although the company tries to make up for it with stock and soft benefits like nice space, good kitchen and soon.
