Pros
I've never worked for a better organization in my life and would like to retire happy and old as a Zillow employee. Google-style environment with game rooms, nap stations and desks with treadmills. Base salary plus competitive compensation plan, amazing benefits, catered meals weekly, monthly retreats/getaways, free snacks/foods/beverages daily, complementary fitness classes, comprehensive training program, tons of bonus giveaways and plenty of upward mobility.
Cons
Nothing negative to say about Zillow as an organization. The job itself is extremely difficult and there is no room for "off-days"; it's not for the feint of heart. For those not self-motivated, I suggest you steer clear.
