Apple Software Engineer interview questions

Contacted by recruiter via LinkedIn. Then short convo w/ recruiter, followed by a call with team manager, then coding interview. Was ghosted after that. My email software even shows when they viewed my follow-up emails! Very unprofessional. What if a prospective engineer wanted to apply a few years down the road after their skills had improved, but were so off-put by the unprofessionalism they wouldn't bother. Even a quick copy-paste template reject email goes a long way. Have had much better experiences with other big tech companies like Facebook.
