The process took 2 weeks. I interviewed at Zillow (Seattle, WA) in October 2010.
Applied online and had a phone screen with HR set up a few weeks later. Had a fairly straightforward phone screen with HR and then a phone interview with the hiring manager. All the questions were pretty straight forward behavioral interview-type questions (ex: tell me about a situation where you worked with a difficult employee and what you did to resolve, etc.). I thought the interview went well, but was declined shortly thereafter. I followed up with their recruiter to see what I could do better, but did not get any response.
Your feedback has been sent to the team and we'll look into it.
