Whitepages Software Developer interview questions

Emailed me with a Hackerrank challenge. No call from any real person, and email response was automated. Coding challenge took me 3 hours, did it genuinely. Checked later and found it was a hard leetcode question with a twist, and I still didn't get to go to the next step even though I met all the requirements. I doubt anyone actually looked at my code. Total waste of time.
