BookBub interview questions

Similar to another reviewer, I went through 4 rounds of interviews for the Growth Marketing Manager position in the fall. They initially reached out to me in early September for an interview, and the process did not conclude until mid November, so a 2 month process for a role that was not even responsible for managing anybody, I felt as if I was answering the same questions over and over again, and interviews went on for 2+ hours, with a revolving door of characters asking the same questions again. There was a take home project that I did that I'm not even sure anybody reviewed. I brought it up a few times on my interviews, and people just looked at me with dead eyes and changed the subject. After 4 rounds of long interviews and a take home project, I was told I did not get the job. I did some research, and could not conclude that anyone at all had been selected for the role. I don't mind being turned down, but it hurts knowing they hired no one, and the process was likely a formality.
