Masterpiece Studio interview questions

Applied March 2022. I had one video interview which took me about 30 mins with the head of R&D. He said the next round will be a 30-minute presentation. It took me about 2 hours to get prepared for the presentation. On the interview day, he canceled on me at the very last minute saying some emergency occurred and he would like to reschedule, but I never heard back from them. It was a very unpleasant experience. I hope they respect applicants' time.
