Pros
Zillow views their employees as its most important asset and you can see it in the way we are treated. The workplace is transparent and the product teams are kept small so there can be autonomy to move fast and make an impact. I'm generally skeptical of things like "core values", but Zillow has managed to roll out these big company concepts in a way that feels genuine. We're in a transition from a small company to a relatively big one (2k+) and the leadership team is taking deliberate steps to have the right amount of process to keep things running efficiently. There's a strong emphasis on over all quality of life. Generous vacation, good parental leave (which everyone actually uses) and a culture that doesn't expect you to be connected all of the time. Zillow has a dual-class stock structure that allows the Founders and CEO to have complete control over direction of the company, allowing for a long term vision. It exciting that Zillow is able to invest so much in the future, tear-down and rebuild business models and expand into adjacent markets even if it limits near term profits. No concern with activist investors here. Overall the best place I've worked.
Cons
We're pretty spoiled overall though the pay the benefits aren't quite as good as the "tier 1" tech companies (Google, Facebook, Microsoft), though they are getting better every year. Things change quickly so it could be a tough place to work if you want consistency.
