Deel Sales Development Representative SDR interview questions

I found the process to be unprofessional and frankly bizarre. I had gotten to the second round interview an had been told later that day that I was successful and had made it to the final round, and arranged a follow call. The next day I receive an email stating that they had cancelled the follow up interview and that I was not successful. I had requested feedback on where I had went wrong to which I had not received any response. I don’t have an issue with not getting to the final round but the manner in which TA handle the process was again unprofessional and disappointing.
