Applied online and was sent a coding challenge that included stringToLong() and insertion/deletion in a ternary tree. Heard back the next day and scheduled a phone interview with an engineering manager. That interview included basic background questions and an easy "return the first unique char in an array" question. I did well and got a second phone interview. That interview was with a more senior manager and included open-ended questions about data structures ("what are some properties of a good hash function?", "Java provides two standard implementations of the List interface, LinkedList and ArrayList - why? which one is better for what?") and a binary search coding question. Finally I interviewed at Zillow in Seattle. They paid for a 5-star hotel, meals and transportation and the process was very nice. Had 3 1-hour interviews with increasingly senior engineers. There were two integer array questions that required a little bit of math, and I was asked to implement a hash table. Overall I was treated well and happy with the process. They were nice people and I would have liked to work there.

The first round was a tech screen with one simple DSA question. The final round had two interviews (15 min behavioral & 30 min technical). Expectations are to complete 2 questions in 30 min and use Zillow leadership principles.
