Hive Customer Operations Specialist interview questions

In the first interview with the HR I was supposed to meet another person than the one that showed in the meeting, Nevertheless, I received a case study right after the meeting and I was supposed to work on it in one day plus the weekend. Now worries I committed to the plan and send it before the deadline. After 3 days I received a general feedback saying that "we have decided to move with another candidate" its a joke at least share a feedback proving that you actually read the case study.
