Apple Software Engineer Internship interview questions

The initial phone screen was just a simple coderpad interview. The team was for Safari. They seemed to be looking specifically for students that have had Mac/iOS development experience. The total time lasted about an hour. It started off with a simple review of what the team was like but we quickly jumped into the technical portion. The last few minutes were left to answer questions.

Applied through referral got an email a couple days back saying a team was interested in interviewing. Interviewed and never heard back even though I emailed my recruiter twice. Had to find the hiring manager's email and email them for feedback and a status update. The recruiters were very unprofessional for not being able to send a one line email saying they were moving on with someone else.
