Grasshopper interview questions

After applying(by HR company), they sent me a HackerRank technical assessment which included two medium-level LeetCode questions - one on DFS (Depth-First Search) and another on string manipulation. The test duration was 120 minutes. I successfully completed both questions with 100% test coverage, but unfortunately, I haven't received any response or invitation for the next interview round.

2 hour HackerRank test focused on algorithms. 2 questions on 1) a depth first search algorithm, 2) string tokenisation. medium difficulty but covering all edge cases so that tests pass is time consuming.
