Apple Developer interview questions

Initial recruiter call, then 1 hour technical screen(this went well), so got virtual onsite of 4 rounds. Out of 4 rounds, first one is coding+technical questions(around java/spring boot), second one(LLD), third one(HLD), fourth one(Product thinking round). All interviewers were good, except for the one in the second virtual round who asked LLD, he was unsatisfied with my LLD, which is totally fine, he could have just sent a feedback but instead yelled and made a comment that my design was brutal, never heard these kind of words during interview. The recruiter was super interactive up until virtual onsite interview but din't even turn into giving atleast a rejection mail even after a followup.
