Apple Software Engineer interview questions

The interview consisted of two system or object oriented program design questions. This was followed by one behavioral interview with a tech lead, Lastly, there were two coding problems, leetcode style. Recruiter never told me about any coding language requirements, but once I get to the interviews, they had a specific language that they wanted.

10 rounds, extremely domain specific, lots of leet code (medium / semi hard) questions mixed with behavioural questions. 6 interviews back to back, each of 45 minutes for the virtual insite. Prepare well based on the job description as all interviewers focused on high level of domain knowledge
