Zillow Software Engineer Internship interview questions

After talking to a recruiter at a University career fair, had an interview at my university that lasted around an hour. Followed up with a Seattle-office onsite that included 3 interviews, each about 50 minutes. Finished onsite with an office tour. Each interview had a technical aspect and a few minutes of behavioral questions and time to ask the interviewer questions. Final decision released within 2 work days of onsite interview. From career fair to final offer the whole process took a little over a month.

I spoke to a couple of engineers at the career fair at my university and then heard back a little while later about an on campus interview. The on campus interview was mostly technical, just a couple of behavioral questions. I had two coding questions. I solved both of them and answered some questions about runtime/optimization. I heard back a couple of days later and they invited me to an on site interview at their office in seattle. I had three 50 minute interviews that were similar to the first round interview (just basic data structures/algorithms). They got back to me the next day, saying that I got it!
