The interview process was very organized.

First, I had a phone screen with an engineer, which was completely technical with a few coding questions. There were no questions related to projects.

Next, I had another phone interview wherein I was asked to design a hub accepting network connections and routing them as per destination given (basic design discussions, data structures, etc.).

The onsite interview consisted of five 45-minute interviews and a 1-hour lunch with an engineer. The five interviews involved whiteboard coding and system limits questions.

One thing that was unexpected was when I was asked about deriving the complexity of finding the intersection of two arrays using different methods and taking into account disk access/latency, etc.
