I was contacted by the recruiter about the position. I had one 45 minutes phone screen interview with 1 easy and 1 medium difficulty problem. I got an invitation for on-site interview after a week of waiting. On-site interview consists of 4 interviews 45 minutes each. Most of them are regarding algorithms and data structures, namely Arrays, Hash Tables, Graphs etc. Interviewers put a lot of emphasis on cultural fit and Zillow core values. I finished with most problems in time. Got rejected without any feedback a week later.
