AAVALABS interview questions

It all started well, with a video recording to be sent plus a live interview with the HR Director. I was also invited to do the next step, which is a case study, attention test and to record yourself about how would you solve a problem. After sending this, I have been ghosted for nearly two months now, and none of my emails requesting feedback have been replied even. I am deeply concerned for the health of the HR Director atm, or alternatively for things working like this in this company.
