I applied online and was first interviewed by the HR recruiter. This was a standard HR screen that you can expect at most companies. The second interview was a phone interview with the hiring manager. It was pretty standard again but included more detailed discussion about my past experiences and technical knowledge. It turned more conversational near the end, which was very pleasant. The final round interview was at Zillow HQ in Seattle with multiple 1:1 interviews for two hours. This went even more in depth into past experiences and both parties made sure there was a right technical and cultural fit for the role and company. Overall, it was a great experience and was definitely one of the best places that I've ever interviewed at.
