I applied online and received an email for a HackerRank assessment. It wasn't too tough, but there were a surprising number of questions for the given time frame (I believe there were four questions to complete in one hour). The questions were comparable to LeetCode Easy to Medium difficulty.

Later, I received another email stating that the HackerRank went well, but the positions had already been filled. The next step would have been a final round interview.

Hackerrank questions.

These were very typical LeetCode easy-to-medium difficulty problems, designed to be completed in about an hour.

There were a large number of questions, about four.
