Apple Developer interview questions

I got the interview on career fair, and the interview was at next day. The engineer gave me one problem to solve, not the normal leetcode question, but a design of system, which is very difficult for me. But the recruiter is very smart and kind.

Recruited on LinkedIn instead of their careers page. Had a chat with recruiter who told me she was building a team like she was the hiring manager or something (yeah right). I had to sign an NDA before I got the interview, however I was still told the project was confidential even though I had signed the NDA. Then had an hour long phone screen where I was rejected 10-15 MINUTES after the phone call. "Not a fit." Very rude interviewer who tried to cut me off multiple times when I said I was thinking about the answer and just moved on to the next question like he didn't care or already made up his mind. After asking the interviewer how I did, he said he would have to "look at his notes" which was a clear sign that he didn't want me. No rejection feedback was given and emails were not returned.
