Activision Blizzard interview questions

Had 1 HR interview, 2 technical interviews and an assignment. First technical interview was C++ questions. And after that I got an assignment that should take a day or two. And then another technical interview that was mostly about the assignment The process was quite slow. I didn't hear back from them and they didn't answer my email

After meeting with the recruiter, I spoke with the hiring manager. The hiring manager asked about various skills and experience related to ML or MLOps and asked coding questions. The question itself wasn't difficult, but the interview was introduced as an exploratory call, so I was surprised to be asked about technical details. Because it did not match well with my experience, the interview did not proceed further.
