Apple SWE Intern interview questions

I received a 15 min video screening from Apple one month after application. It was not a pleasant experience. The interviewer was late for 6 minutes, claiming there were some technical issues happening. Also, in their invitation email, they told me to wear business casual, but the interviewer is dressing extremely casually. After this call, I got rejected.

Sent in resume through a career fair at college, got an email to schedule two interviews with them after, and did two interviews for two consecutive days. Heard back from them about the result around a week later
