Don't waste your time with them.
It's a very long process, approximately 2 months with a total of 7-8 interviews.
In the end, they reject you for non-specific reasons.
They pass you around between different recruiters and then no one knows anything about your process.
My worst interview experience has been at Zillow.
They demand a lot of time in their process, and in the end, they don't even give you valuable feedback, looking for reasons to discard you, even though you pass the interviews and do very well.
