Had a first-round telephone interview, and then I was brought in for an on-site that lasted about 4 1/2 hours with 5 people (3 technical rounds). This position was also listed as a remote opportunity, but they changed it to on-site at the last minute. I was extremely excited about this position until that happened. Zillow is an open-office environment. No one (not even managers) has their own office. As an introvert, my stomach sank when I toured the floor. I'm betting companies like Zillow are missing out on a lot of talent by having this setup and not allowing remote work. Open offices are not for everyone.
