I can only speak on Data Services, and if you were thinking about applying to DS, just don't. Management will ensure that you know you are at the bottom, and will go out of their way to make you remember it every day. The will gossip, openly judge you about non-work related aspects, and prevent you from ever trying to progress professionally. Zillow likes to shout that they are a great place to work, but there have been multiple occurrences where employees have tried to speak up and the result was always the same: nothing. Then based off previous comments to reviews they will reply with "we have not heard this level of feedback prior". Unless someone along the chain is purposely preventing them from hearing this feedback, then this just goes to show how hard they work to keep up this facade of a great place to work.
