Process
There was an online coding challenge followed by two rounds of phone interviews.
The first phone round was theoretical questions, and the second round was more coding.
The initial coding round was powered by HackerRank and required solving two questions in about three hours.
The questions were fairly simple and based on BFS and general data structures.
Questions
Data structures and algorithms-based questions were asked. There were also some theoretical networking-related questions.
