I applied through an employee referral. The process took 2 weeks. I interviewed at Zillow (Seattle, WA) in Mar 2013
Interview
Zillow started the interviews by sending me a coding question to complete and return to them. I then had a phone interview that had basic questions about my resume and my interests as well as some high level algorithm questions. Then they flew me out for 3 one on one interviews each was 45 minutes. There were a mix of string manipulation questions and data structure questions.

I turned in my resume through online and got contacted from HR. After some weeks, a recruiter emailed me with a couple of technical questions. I then had a phone interview that had basic questions about my resume and my interests as well as some high level algorithm questions.
