I applied through a college or university. There were two coding rounds, one hackathon, and two interviews. The coding problems were mainly from the graph data structure. The hackathon problem was an extension of the lockable tree problem, in which we had to make a tree thread-safe, involving multithreading concepts. After that, there were two interview rounds. I was rejected in the final interview round.

The questions were Lockable Tree and Set Matrix Zeroes from LeetCode.
