Zillow Data Center Administrator interview questions

Received a short, less than 10 minutes, call from Zillow recruiter and scheduled interview for later that week. In person interview was 5 one hour sessions with 1 or 2 employees at a time. The day after I thanked them for the interview via email. I followed up at the end of the week and was told they hadn't made a decision. Called another week later and was told the same thing and that they would contact me when they had made a decision. In the interim I found a job and forgot about Zillow until they contacted me via email 3 months after the interview to say that I hadn't been selected. Thanks, I assumed as much.
