Apple Software Developer interview questions

Question about domain and day-to-day current work. 1 LC easy question was asked in the end. Interviewer and recruiter were a bit rude. Didn't do great on interview and then ghosted when asked for feedback.

Received mail from apple for software Engineer role. Later they schedule the interview with hiring manager Ask about product i am working on? While explaining the details, seen interviewer being sleepy and not able to concentrate! Whats the point of such interview? When i ask for feedback, they wont provide.. How will they provide feedback when interviewer was sleepy!
