Process
I applied through a recruiter. The process took three weeks.
There were three technical rounds. It started off with an HR call. The first interview was a resume deep dive and a medium LeetCode question. The second was a hard LeetCode question, and the third was a systems design question. Finally, there was an HR call to negotiate.
Questions
There was a LeetCode round on the binary search tree algorithm.
Then there was another LeetCode round on the SSSP graph.
