I received a HackerRank coding challenge, which included one easy and one hard graph problem. I correctly solved both challenges, but then received a rejection stating, "Score was not sufficient."

I followed up, stating that I had a perfect score, but received no reply. I was really interested in this company; I wish they would have given a proper explanation for the rejection.
