Apple Product Designer Engineer interview questions

Initial phone call with the recruiter, then a 45 minute initial screening with a manager. Was asked about my experience. Not many technical questions. Was contacted by the recruiter a week later and given a design challenge. Had 2 weeks to complete the design challenge. After I submitted, I was scheduled for an onsite with 6 people, 45 minutes each and the recruiter for 30 minutes. Then presented my design challenge for an hour with the team of engineers where they asked design decisions. I was given 5 minutes at the end of each interview to ask questions. After, recruiter reached out telling me the team wanted to bring me on board, then GHOSTED. The interviewers were friendly but the process is arduous and leaves a super bad taste to not have the courtesy to follow up after I spent so much time interviewing. The process was also SUPER long and the design challenge took 30+ hours to complete. Crazy how much time commitment they expect. The entire process from the initial contact with the recruiter has been 3 months.
