Got a hackerank immediately after applying, with what seems like a fake recruiter with 2 questions that were near impossible. Definitely feels like a fishing and data collection sort of company. I made a report to FTC as well. Got an instant reject

After completing the HackerRank assessment successfully (the platform tells whether you answered the questions right or not), I received an automated email saying that they will not move forward. I answered the questions correctly. What was the criteria to make decision? Either give feedback for candidates or do not waste their time.
