I got invited to the initial interview with an HR representative, who happened to be an intern. The interview felt very unnatural and the interviewer seemed to be pacing through a checklist of questions, all the standard initial ones. She came across very unfocused on what I said, in the end she also admitted (and apologised) that she was focusing on something happening at the office at the same time. Highly unprofessional and in that moment I decided that this is not a place I'd like to work at. She said she will get back to me the next day, but I got ghosted!

Very positive. I got to learn more about the culture and the role. Three interviews, first with hr (about Criteo), second (about me) and third (technical skills) with team members.
