Recruiter call, very direct and informative. Hiring manager call, background overview somewhat technical. Then a homework assignment. They want you to spend 3-5 hours on it (it's a kaggle question), and they say they will know if you only spent an hour on it. Then a presentation/discussion on the homework. It was clear that the interviewers had not meaningfully reviewed the homework submission. I believe there would have been three more rounds, but I withdrew, the process was too one-sided. At more senior levels, interviews are an interaction to inform both sides, this process was not that.
