Apple Software Developer 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.

Specific teams at Apple hire rather than company first, then picking teams. Had an employee referral to her team and received two initial phone screens before the on site interviews. Made it through both phone screens, then the recruiter ghosted me. Very unprofessional.
