I received an Online Assessment (OA) email on the day of my application.

They provided a list of helpful links on how to prepare for the assignment, including a full demo of the process and the coding environment, which behaved exactly like the real HackerRank environment.

The OA had two LeetCode-style questions. Both had very long descriptions and took some time to process. Beyond that, the questions themselves were quite difficult; the first one was easier than the second, but still challenging.

I did not perform well enough and was rejected a few hours after completing the OA.

Two difficult array-related questions.
