Apple Software Developer interview questions

Applied through portal. They scheduled first round.After the first round is done, recruiter is vanished.No reply to followup email and call .After one month, they sent mail which says rejected.Such an unprofessional recruiters

Referred to Apple. Went directly to a technical interview. The interviewer did not wear a headset or headphone, which he directly spoke to the mic on his Mac/Laptop. His voice was not clearly and the question was not explained well either.
