Zillow Software Engineer Intern interview questions

One initial technical interview. Then a week later two technicals back to back. They asked me complex system design questions when I was only a first year. I think they expect people who already have some sort of background, despite being an entry level position.

Passed the take home coding portion and the first phone interview. Second phone interview was doing some coding on an online compiler. Wasn't hard, but my interviewer did not seem enthused.
