I had a phone call for about 30 min asking for my past and my expertise and after that an interview with head of data, they were kind and asked more deeply about everything I did in my work.

The first interview went really well. It was more like a conversation. I was told that I would be contacted for a second interview but never was. I contacted the hiring manager that I interviewed with and was told that I should have been contacted and they would follow up. About a week later I received an email asking me if I was available the next day for a phone interview. I had to rearrange some plans but I made myself available. The phone conversation went really well and even went beyond the allotted time period. When it ended I was told that I would be informed about next steps and I never heard anything back. I followed up but was ghosted. I thought I would at least receive the "thank you but we went in a different direction" email but I didn't.
