Pros: The biggest thing that sets Zillow apart from other places I've worked and from where many of my friends work is the people. Zillow has a very open and friendly environment that encourages collaboration and growth. It isn't just your coworkers, though. Management, from your direct management to group managers and even VPs, is invested in you personally. They care about what you're working on. They care about what you want to work on. They care about making sure you aren't working too much. That you are happy in your position and team. They care about your career development. There is a lot of support from all sides, and no issue will go unaddressed.

Cons: Zillow is a medium-sized, fast-growing company. That means it has all the medium-sized company problems: frequent team reorganizations, cross-office communication problems, and growing pains from trying to rapidly leave old, crufty systems. It's not bogged down by bureaucracy yet, but it is definitely infected with some old code.

Pros: Enthusiastic upper management clearly communicates the company mission and goals. It's fun to work with so many talented people. Senior management makes a point of recognizing employees who go above and beyond and make great contributions to the company.

Cons: Average pay and benefits. Company expanding very quickly and playing catch-up to accommodate new growth, both in terms of office space and development infrastructure.

Pros: This company has a good environment.

Cons: The con is, sometimes the requirement is too high.
