I had a coding exercise, followed by a phone interview, and then an onsite with several different interviews. The interviews were highly technical and focused on distributed systems content. They gave very detail-oriented questions and challenged me to be confident in what I was talking about, but they also were helpful and supportive. I was surprised to be asked such specific questions about distributed systems over a phone screen, but it made me more excited about them since that was what I wanted to be doing. They provided me lunch at the onsite and had people there to talk with me about the company. A few of my onsite interviews were over video chat because I was interviewing in Seattle, but their main office is in San Jose. I did not really mind.

Explain how you would organize metadata for a distributed database as it scales.
