Online hire vue interview, 6 or 7 questions, had to record video answer to the questions, you have 1 chance to re do the answer if you're not happy with it

Overall, the process was ok, I had all of my interviews in their office, and first rounds were great. After that, they gave me a couple of case studies to work on for 2 weeks, and then I did a presentation in front of the team. I didn't get the job and never heard from my HR agent (which sucks) but I somehow received the information that I didn't get the job directly from RB person. The reasons sounded lame, smth like "no one was good enough this time so we will start interviewing for this position again" but the position never appeared on their website or LinkedIn again. Feels like a waste of time considering that I put a lot of effort into those case studies and IMO they were pretty good.
