DataCamp interview questions

The interview process moved fast until I was ghosted. I did the HR screening, at the end of the call I was immediately scheduled for the interview with the hiring manager. Before the 2nd interview I had to do a compulsory AI knowledge assessment. The second interview went well and I was invited to deliver two case studies (one take-home that I had to deliver beforehand, and other one that would be discussed live during the interview). The case study interview was done with the hiring manager, head of demand gen and COO/co-founder. After few days I was told they chose another candidate but I never received feedback on my interview which I think it's the minimum after all the time spent preparing the case study. HR never got back to me, I also sent a LI message to the hiring manager (who connected with me) but never got a reply. Being this the final round, it would be fair to receive some more details on why I wasn't selected.

2 months, 4 interviews (including HR screening), ghosted at the end. All emails for updates on the process and any feedback has been ignored by everyone at the company. It doesn't appear this place has any respect for interviewees time.
