Apple Data Scientist interview questions

Super long and tedious interview process that spanned multiple stages: HR screening, Hiring Manager screening, Technical assessment (SQL), Case Study + presentation to a panel of team members, Final rounds with 5 separate 1:1 interviews (behavioral, product sense, statistics). For the case study, we were given a dataset, a a problem statement and a week to put together insights/a presentation centered around A/B testing. The final round was most challenging, involving multiple behavioral interviews, a product sense interview and a philosophical debate on Bayesian vs. frequentist statistics after reading an article that the interviewer wrote. My experience during the final rounds was very negative. One interviewer had a poor connection which led to a very awkward conversation where we couldn't understand each other. Another interviewer was constantly distracted and left 15 minutes early. And finally, the debate was extremely combative and the interviewer came off as a know it all. After the last interview, I did not hear from the recruiter for 1.5 weeks. I was finally rejected after I sent a follow-up e-mail.
